Thanks Erik. Appreciate the kind words! Clear skies, Nico

I personally own the 14-24 EF, its served me quite well for Milky way and was super helpful on my Grand Canyon trip back in February. Thanks for checking all these out for us!

Super presentation as usual Niko. I just recently purchased the Tamron 15-30mm F2.8 lens after returning a failed Rokinon 14mm. Seeing some of the artifacts and distortion in the corners during your presentation has helped provide a rough baseline for comparison and I'm feeling much better. I'm also toying with the idea of picking up a mirrorless camera, so this has helped shed some light on both the camera and lens.

I started off with the Sigma 20mm, sold it for the Sony 20mm f/1.8. That new Sigma 20mm is good as bought from what I'm seeing. One thing Sigma could do to further "give the nod" to us astro folks is something similar to what Samyang did with their 24mm f/1.8 tiny prime. That is have a function that when engaged automatically focusses the lens to infinity. I use this all the time on my E-Mount cameras and it has proven to be very useful. Top video Nico, really well done!

I've been looking for this videos for months! Thank you very much for this outstanding video! Literally, no KZread astrophotographer took this amazing initiative.

Hey Nico! I just want to say thank you so much for all of your content. I dabbled a bit with Astrophoto last year and bought a star adventurer 2i but never had a tripod sturdy enough to hold it steady. I ended up just not using it all winter but then (thanks to your videos) I was re-inspired to try again this summer. I bought a better tripod and started trying to get things going again about a month ago and I went from taking reallllly crappy photos to some-what decent photos! I would say 80% of what I learned is from you! If you’re interested I made a little short 1:20 video about my recent best imaging session that’s on my channel. Really not trying to plug my channel (it’s my only video) I just want you to see what you inspire! Thanks again for everything you do!

What a fantastic video! So much work went into this, clearly. I own the Rokinon, and it is not great in the corners, as you pointed out. I will upgrade when I move to mirrorless! Thanks again!

This was a great review and had to be an insane amount of work. I appreciate the hard work and the information

Excellent review! What i'd like to see Sigma incorporate in the new 20mm and 24mm lenses is an option to dedicate the focus hold button to focus on infinite. Or at least the same way the latest Samyang/Rokinon lenses incorporate this feature to instantly focus on infinity when holding the focus hold button when turning on the camera. If this can be accurately programmed, it's a beast in combination with the manual focus lock button.

Thanks for putting in all the work for this very useful comparison.👍🏻 I pre-ordered a new Sigma 20 for this Aurora season. I love the 20mm focal length and have been waiting for a 20mm f/1.4 with good corner performance. Looks like this may be my 20mm Holy Grail lens. 🤞🏻

I am so glad I found this video. I was very much considering buying ef versions of the 20mm and 24mm and adapting them, but now I think I may go a native E mount 20mm and ef 28mm

Thanks for the video, i strongly consider the 24mm DG DN for milkyway panos. One thing that would be great to see on a focus by wire lens, would be a programmable button that automaticly focuses on infinity, i saw it on one of the new Samyang lenses for E-mount.

This was just what I needed to help pick a lens. Going from a kit lens zoom f/4 to a prime f/1.4 is going to be huge for my time lapses!

I plan to buy DSLR lenses to adapt with my camera: I do this because, I mean, they're a bit slower to focus, they're not as sharp, but they are adaptable to my camera and to a future astro camera with it's adapter. Only issue is that I have to do some manual stuff to keep the aperture opened to the max or even stopped down since the adapter for the zwo doesn't provide any kind of clutch for Nikon lenses

Thanks for this comparison! Presently I only have a zoom for the ultrawide range (Tamron 17-35), so I hope that Sigma introduces the 24mm f1.4 for the Canon RF mirrorless mount in the future, since the performance of this new design looks great, and significantly better than their current 24mm f1.4 EF-mount DSLR design.

Wonderful video. I'm really excited for the Sigma 20mm. One notable correction, and one of the reasons I've chosen Nikon for astro: You can adapt any of the mirrorless lenses to Nikon. There are multiple Sony E->Z adapters, and the new Megadap ETZ21 is wonderful both for astro and for daylight. The Sony lenses are really fantastic, and combined with Nikon's not eating or turning stars green, it's a winning combo.

Very nice review. Something of note: Nikon Z mount does have a couple of adapters to Sony E lenses.

Those adaptors being Techart TZE-02 and Megadap ETZ21. I think there are also Nikon Z to L mount but I've not looked into those.

Wow! Those are impressively thin. That is an interesting advantage to the Nikon Z having the smallest focal flange distance of all the mirrorless cameras (16mm). With my Canon RF stuff being 20mm, I will never be able to adapt L-mount, Sony E, or Nikon Z glass to it.

There are a handful of amateur astrophotographers that make this hobby accessible to the poor beginner (many have grown) Kamil Pekala is one I discovered in November last year. I've been following you for a while, was delighted to see you present on T.A.L.K! This site is beyond the former by and large. I use a gen 1 Star Adventurer, and MSM. Kamil convinced me 50mm Sigma Art was a great prime. I also bought 35, since I have an astromoded Rebel t7i (APS-c). Into cine as well. Saw Rokinon "4 pack" of cinema on BH for a nice price, so I too have lens you do(and probably the other 3). I recently bought Sigma 20mm CANON AF. After seeing this review, I might try to exchange it for 24mm. I'm not doing mirrorless for obvious reasons. Just did Cephius region for Bubble nebula and it's "friends " with the 50 Sigma (80 equivalent)past Friday and Saterday. Your content keeps me inspired ! THANK YOU most sincerely.

Cheers Mike. I love lens-based astrophotography, esp. deep sky with lenses so I don't see myself ever fully moving on from it.

Regarding the focus by wire I start using it many years ago with my Zeiss Batis 25mm f/2. Couple of years after that, I got the Sony 20mm f/1.8 G which uses the same system. This is infinity better than machanical. First, there is acceleration, depending on the velocity you move it respond with larger changes for the same movement. Second, it has a focus cheking where we fast move the ring and it tests the focus and stops if the camera thinks it is focussed. Also, without a limititation of the ring movement we don't move the setup for macro photos where DOF is so short. Besides, for Zeiss Batis lenses the DOF is shown at a LCD at the top of the lenses. No need to check hyperfocal tables. I have other Sigma DG HSM lens and it also presents this strange chromatic aberration your 20mm presented. It also presents the stars distortions.

I really hope so too. It seems Canon is being a bit more clear with third-party lens manufacturers what they can and can't do with RF. It is a shame that Canon has to be this way but at least there will be some third-party lenses, or so it seems. I need a fast wide prime right now so I think I will have to go with the Sigma 20mm and use the adapter.

Great review! Thanks for all the work in assembling it. The better lenses from all the manufacturers for mirrorless cameras is one of the best reasons for switching from DSLR to mirrorless, certainly for us astrophotographers. But it seems all are sacrificing uniform sensor illumination to optimize the other qualities, and in doing so are depending on in-camera and raw processing corrections to “flatten” the field. The new DN Arts look great, but the question many - including me! - want to know is when will we see them for Canon RF and Nikon Z. Neither camera company has opened up their system to third party lens companies. We keep hearing rumours of a Canon-Sigma deal but nothing has appeared yet. I look forward to your test of the Sigma cameras. Being able to use the Sigma DN Arts is one good reason to buy one. The question is, where in North America can you get one filter-modified? Legault used a European dealer. Clear skies!

Thanks Alan. I am not ready to modify my fp yet, but I will start asking around to see if any North American modification shop is willing to take on the Sigma cameras. If I can find a shop that will do it, I might buy another fp to have modified as they are pretty reasonably priced considering how capable they are.

Great comparison Nico. I am considering getting a 20/21mm like the Rokinon 20mm F1.8 instead of carring both a 14mm and 24mm (I have 35/50mm F1.4), and wondered if anyone else has done this. Possibilities aren't so many for Canon, but there is also a Zeiss Distagon 21mm F2.8.

Awesome review

Thanks for this video Nico. I've been thinking of which wide prime to get. So far I've been using a Samyang 14mm 2.8 manual, and my Canon 24-105 kit lens, but I have to use them at f4 for reasonable sharpness. I have a tracker, so they work fine for that, but it would be amazing having lenses that are usable at f2 or even f1.8. And even at f4 my lenses have worse corners than some of these do at f1.4! I think the sigma 28 seems the best way forward for my canon 6Dmk2.

@NebulaPhotos

Жыл бұрын

Yes, I agree. The 28mm is an amazing value for one of their best lenses. So far in my testing, my favorite Sigma Arts available for EF mount have been: 14mm f/1.8, 28mm f/1.4, 40mm f/1.4, and 105mm f/1.4.

Great comparison,thanks

Thanks for doing this, I know how difficult and how time consuming this kind of scientific comparison compare to the typical KZread lens review, greatly appreciated, you deserved a lot more than just a " like". I also have some of those lens on your video and your finding totally mirrors mine, I really can't find any flaws from the 14 and 20 F1.4 DG DN except for the high level of vignetting, which is pretty easy to correct in post. I thought I was the only crazy guy thinking the DLSR Sigma 28 F1.4 is still great today against all other lens in that focal range, and your review demonstrate that as well, DG HSM Art lens, it's probably the most technically perfect lens Sigma has ever produced, and that lens never got any attention and I hardly see anyone shooting with it in the field. I also used to own the DSLR Sigma 20 and 24 F1.4 HSM but so disappointed with those and replaced them with the Sony 14GM and 20G as soon as those came out. I shoot with multiple systems so I can just pick the lens I like and use them on different bodies.

I own the Tamron 15-30mm f2.8 and Sony 20mm f1.8. The Sigma 24mm f1.4 looks like the best candidate for my next lens also for street and travel.

Thanks! That's a really harsh test of camera lenses + viewing them at 300%. The 2 soft in the middle lenses appear to me to be slightly out-of-collimation, i.e. flared stars + sharper one side than the other. Mirrorless lenses benefit from the latest computerised designs, shorter backfocus distance and, for Nikon, a larger mount (Z vs F).

Awesome video.

Excellence review.! Thank you

Since you had a cine lens in your lineup and mentioned being into cinematography at one point, I'm going to take advantage of the opportunity to hopefully get a couple of questions answered, or at least make progress in finding out the answers. I have several cine lenses by Samyang/Rokinon, but I am not into cinematography (right now), so I have no knowledge of the niche. I started getting them because they were on special - 24mm and 35mm brand new, each about $200. I've enjoyed the performance I've gotten from them, and I've come to prefer them, at least within the Samyang/Rokinon brand - I now have 4 or 5 of them. I've read reviews and comments from amateurs and professionals. Some say, as you did, it's the same lens as the non-cine, just in different housing. But some, even professionals, said that despite every indication of them being the same, they actually seem to be a little sharper than their non-cine counterpart of the same model. I've scoured the internet looking for articles or videos that might do a deep dive into 1) whether or not it's true, and 2) why. The only thing I can come up with is that the focus range (in terms of how much physical play you have in the rotation) is more generous on the cine lenses and therefore you can do more to dial in the focus - my theory, based on what I've read and seen. So, question 1) do you have an answer about whether or not they are sharper, or can you point me where to find an authoritative answer? Question 2 has to do with the aperture ring on one of my cine lenses - the 35mm. It's a Nikon F-mount. Only when attached to my Nikon, the aperture slowly turns itself to the widest T1.5 spot. If it isn't attached it will stay wherever I turn it, and if I attach it to my Canon EF camera (via an adapter ring) it also stays put to wherever I turn it. So something is engaging a spring within my Nikon camera to turn the aperture to T1.5, but it only occurs with that lens. My other cine lenses, all Samyang/Rokinon and all Nikon F-mount, don't do that, and they all appear to be identical on the rear mouning surface. I can easily use gaffers tape to keep it place if I want it stopped down, but I'd rather not. Unfortunately, I didn't notice this until after a year of owning it, because I almost always shoot wide open, and I've favored my 24mm for Milky Way over my 35mm. I sent an inquiry to Samyang, but never heard back from them. So, question 2) since you sometimes dabble in the dark arts of equipment tinkering, any thoughts or wisdom on how I might fix this quirk?

@NebulaPhotos

Rokinon makes many different versions of lenses, so we have to be sure we are talking about the most basic, lowest cost photo version and basic cine version when we are making that comparison. Not the 'XP' or 'Xeen' versions for example. Authoritative source when comparing the most basic versions: I asked Rokinon at their booth at a photo show back in 2016 and they confirmed they were the same optically, just a different housing. In comparisons of the photo version and cine version where someone is saying the cine version is sharper, I think they must just be seeing copy-to-copy variation. The Rokinons are notorious for having a lot of copy variation. I've gone through many copys of the 14mm f/2.8 and never gotten a particularly good one, while many people swear by that lens because they were lucky and got a good copy. I've never run into that particular problem, but every Rokinon lens housing I've taken apart has been pretty simply to figure out if you are careful and pay attention, so I'd say if you are mechanically minded and have a good eye for detail, take a tiny screwdriver to it and see if you can fix it.

Great video. I would argue moving to focus by wire for weight though. I mean, they are all still pretty big and hardly light. Most astro guys hate focus by wire, wish they would just do mech as always but here we are I guess!

Wish I saw this before I bought the mirrorless RF mount lens. EF with an adapter seems to be the way I should have went. I have the Rokinon 14mm RF mount for my EOS R camera. The Rokinon CINE is different since it actually looks like a DSLR lens mounted on an adapter. I wonder if there is a mount underneath. Small screws hold the adapter in place. I'm not about to tinker though because so far I like the photos. It is the totally manual CINE version I have. I'm old school so I do not not go for electronic or automatic. I also live in Massachusetts so I deal with the light polluted skies that you know. Your demos are excellent and informative. Keep up the reviews. I also have the Irix 15mm which I find is more versatile in the EF mount. I also have an EF mount camera & an EF mount to a ZWO533 astro camera I use. I got both the Rokinon and Irix at 270.00 each used so I can't complain.

In that recent interview the Sigma CEO said the Foveon X3 wouldn't do well in low light - not sure if he meant for something like video or if it would be particularly noisy for astro too. In any case, I'd definitely be willing to try it out for astrophotography- it's such a cool concept.

About focus - using an EOS R and RF lenses - a common complaint about the cheaper non-L versions is they lack the swtich for manual / AF and instead its Focus or Control Ring. Not many photographers like that but its actually a 'feature' for astro. Set the camera to manual focus, focus the lens then flip the switch to control - no more focus movement. Similar to the Sigma Lock Focus thing. Ironic in a way.

Will you ever do a video about oversampling and undersaming, how pixel size influences the final result depending on the focal lenght? It's a side of astrophotography I never quite ubderstood

man i don't know the first thing about telescopes but I still found this interesting.

Very interesting review, great job 👍 Could you please clarify why there was no colour noise on mirrorless lenses and quite a lot on DSLR versions? By the way is that something wrong with that Rokinon? That lense is very highly rated as excellent astro lense even at f1.4 but based on photos it's far way from its fame. What could explain this?

@NebulaPhotos

Жыл бұрын

I am not sure on the colour noise question. I was pretty sure I had all the lens profiles stuff turned off and it seemed that it was off based on the vignetting, but maybe there was some low level thing happening that was destroying hot pixels? I am still learning about the Sigma fp system so it would require more investigation. Hopefully by the time I review those cameras, I could tell you more. Nothing wrong with the Rokinon. That is very good performance for a lens you can pick up for $430 new right now. Are you seeing a test like mine (not processed other than stretched) on a small-pixel, full frame camera that shows better performance? If you are looking at processed results it is very hard to say much about how the lens is performing as I can easily make it look much better by using tools like the 'defringe' slider to get rid of the magenta/red CA. In terms of corner distortion, keep in mind, I'm zoomed way in- 300% and then zoomed in 2x from there when I zoom the screen. This is to really show the differences clearly for KZread, but for your general milky way shot, no one be looking at it like that unless they were a true pixel peeper like me :) But from testing many lenses, I can tell you the vast majority have similar corner distortion to the Rokinon. Those three Sigma lenses that did so well are quite a rarity in the world of wide-angle lenses.

Great video... my only issues with mirrorless is that they are easy to collect dust and other particles in the camera. My best friend has had one for years and the issue of dust and other particles collecting on the sensor has been his major complaint. He has to have it cleaned (the sensor) three or more times a year (depending on the environment). The dust and particles are introduced, on to the sensor, basically when the lenses are changed. Other than that, the lightweight body is a plus, compared to a DSLR.

Just wondering if I have to go telescope to get it or if one of my lenses is able to get it. Thanks in advance.

@@kevinashley478 Telescope is not required. 200-300mm is the perfect focal length. However, those are VERY difficult objects without filters: the ultimate choice would be mono+narrowband, but color+multi-bandpass filter would work well too. Even a light pollution filter AND a modified camera could work. With a stock camera and no filters, I never had much luck since they are very dim outside of their H-alpha emission at 656nm.

@@NebulaPhotos oh ok. Thank you very much. I plan to get the basic mod, removal of the LPF2, on my T3i. If I am in a Bortle 2, would I still need a filter, or would that be dark enough? Also, after getting the camera modded, is there a filter I can use that would eliminate, or at least reduce, moonlight? I mean if it's like a half moon or less, not a full moon. But if there is a filter that would eliminate or reduce a full moon, that would be fantastic. At this point I would be ok with NASA covering the moon in a flat black dust, or anything non reflective. They say the moon is moving away from Earth and that one day it will leave it's orbit around earth forever. It's kinda wild to think that one day, there will no longer be any total eclipses, that one day the moon will be gone. That's gonna screw with the oceans a bit.

@@kevinashley478 Yes, that will work. It will still 'pop' more with a filter, and a filter would also help with moonlight. The narrower bandpass the more it will block moonlight. With the T3i, I think the best option is the clip-in Optolong L-eNhance.

My favorite for Sony fully frame is the Sony 20mm f1.8. I also have the Sony 24 f1.4 but I prefer the 20mm.

Another great review as usual with lots of great information. I had the Canon EF dslr version of the Sigma 20mm but sold it due to the terrible astigmatism in the corners. Switched to the RF system and while both Sony and Nikon have great 20mm Astro lenses, so far Canon has not produced anything for Astro in a prime lens. Very frustrating and now they are shutting Sigma out so another slap to the Canon customers.

The Canon RF 85 f/1.2 is one of my favorite Astro prime lens ever made, but it’s also very expensive. After renting it several times, I finally pulled the trigger and bought it and don’t regret it. But yeah not much of interest for wide field RF lenses yet. The only one I think is worth picking up is the TTArtisan 11mm f/2.8 fisheye, at $215 it’s a steal.

@nico have you ever tried the Sony 24/20/14

The best 24mm for mirrorless Cameras are the Sony 14mm 1.4 GM, I own it and can highly recommend. The Sony 14mm 1.8 GM are also a very good Lens which I own and can recommend.

My guess is any speedbooster would be a disaster for star shape / image quality when it comes to astrophotography. The optics in those are fine for video, but I don't think they will work well on star fields. Again, this is an educated guess, so if you already have one, go ahead and try it and report back.

How did you go on with lens profiles? The newer sigma lenses won’t have the profiles yet, could make a big differance

@NebulaPhotos

Жыл бұрын

No profiles on anything. I should have covered that! I have seen how profiles (either used in-camera or with Adobe Camera Raw / Lightroom) can correct vignetting pretty well. For single shots, it can definitely be a plus. I need to experiment more about how well profiles work if you plan to use a more standard astro workflow with calibration files and stacking.

@SteveKershaw

I think the profiles are integral to the lens design, I read that is partly why they can make the newer lenses lighter, (for Sony GMs but it must be the same for all modern lenses)

35-40mm shootout is coming this spring.

I have the 20, 35, 50 and 85mm Sigma Art DG HSM lenses for Nikon F-mount. Unfortunately, the 20mm is the worst choice for astrophotography. Maybe, there are a few good versions of it, but mostly I see complaints as well. For Nikon F the 20mm Nikon lens is a better choice, it's lighter, can accept filters and optically better. Recently not much used the 20mm Art for typical astro photo work. It's good for star trails, when I took single 30-40 min exposure, errors will not be visible due to rotation. Used it in Moon lit photos as well, where lot of moon light helps as well. The Tamron 17-35 f2.8-4 Di OSD (A037N) is performing better in the corners, although it was primarily designed to be autofocus lens, the manual focus ring is "loose", thus harder to focus, than even harder to accidentally not de-focus. The 85 Art is the best I have, even in f1.4 astigmatism is minimal to the extreme corners, chromatic aberration is visible, but correctable. Found the Nikon 50mm 1.8 G is equally bad as the Sigma 20mm Art.

@NebulaPhotos

You should check out the 28mm Art for your Nikon. I have it both for Nikon F and Canon EF. It's my favorite wide angle and held up very well against these new mirrorless designs with excellent sharpness and great corners. Cheers, Nico

If I use a tracker, is fast lens still necessary? Many of my lenses are quite good if I stop down

@NebulaPhotos

Жыл бұрын

Definitely not AS necessary, but you will still get a better signal to noise ratio with a faster lens in the same total time. That said, f/2.8 is still pretty fast in the scheme of things, esp. when we compare to most telescopes.

How come the Canon 24mm 1.4 L II wasn't included in this shootout. I would like to have seen how the Canon performed compared to it's peers.

27:08 are you sure that's not an issue when adjusting the focus ? I used to do some of those lens tests and it's still quite difficult to genuinely get the perfect focus while switching 10 times a lens

Also 27:52 not the same photo - grain is different. but yes, it could have been a bad sample of the lens, it happens too. Another thing also to investigate is... the adapter. While the adapter of course fit the lens, in astro it needs to do so very precisely and without any wobble... this is actually very rare and finding a robust and stable adapter is also quite a challenge

Well you mention those after as well ok ^^ But this does complicate an objective lens comparison - had that many times in my own tests

If you have this lens on a star tracker. Does shooting @ 1.4 make it pointless?

@NebulaPhotos

Жыл бұрын

Not pointless, you will get a brighter/cleaner image faster with a faster focal ratio regardless of whether you are tracking or not. For example, 30 minutes total integration at f/1.4 will look more noise free allowing you to stretch further compared to 30 minutes at f/4. That said, if you do have a star tracker, it would probably make sense to at least stop down to f/2.2 where all these lenses get sharper and vignetting isn't an issue.

Ah, yeah, a bit confusing terminology there. There are no 'DSLR Lenses' either in that sense, but the industry (including Sigma) is already using the shorthand of 'Mirrorless Lenses' to differentiate between lenses designed for mirrorless camera bodies vs. DSLR lens designs where they simply added extra space at the end to work with mirrorless cameras. That is the difference, but I should have tried to make that clearer in the video. Cheers, Nico

@@NebulaPhotos Yup. I have to say this decision by Canon is basically a betrayal of all their loyal customers (me for one) who have plunked down major bucks and committed to their new mirrorless system and lifted them back up into competition with Sony. Small minded greedy decision that I hope comes back to bite them so they reverse course. I confess I do like the cameras, (mine is the R5), and many, not all, of the lenses. I'm curious - are there any fast full frame fully manual wide prime lenses that fit the bill for milky way shooting and that are designed with RF mounts? Laowa?

I wouldn't say any I've tried compare to Sigma Art series in terms of sharpness and star profiles, but some of them are pretty fun and could be great for certain applications.

In astro, its cheap to obtain background blur haha - poor focus, etc. In photography, its cheap to obtain perfect focus with no background blur (kind of). I propose a challenge - Astro Bokeh. Super sharp target image on top of purposely out of focus background stars. Maybe Ive had too many beers. Bokehhhh

I don't know of any astronomy- specific capture programs that support them yet, but Sigma has released an SDK (software development kit) so I suspect we will see more programs supporting them if there is some demand for it. I so far have only controlled them with an intervalometer.
