Such a thorough review! Great shots and comparisons!

Totally agree with you regarding Focus-by-Wired, really hate that crap, but unfortunately for Mirrorless AF lens that's what we stuck with whether we like it or not. but that manual focus lock on these new Sigma lenses are really life saver, i can shoot something and put the camera back in my backpack and hike a mile and pull it out again and never have to refocus it again, absolutely love that after shooting with their 20 F1.4 DG DN for a year, as well as the taper front housing for the heater, which is also super nice little feature but makes a huge different in real world use, you really need to use it to appreciate those little details. The tripod mount bracket is also great feature as you mentioned when using tracker, all in all, a really nice lens for Milky Way landscape. As owner of Sigma 14 F1.8 Art, while i think it's really sharp and fast lens, but I really don't care for its Coma performance wide open, so ever since the Sony 14GM showed up I hardly touched that sigma 14 again, I really hope this new Sigma has big improvement on Coma specifically and your sample comparison shows it does. Any chance you can do a comparison between this new Sigma and the Sony 14GM? I have the 14GM but also really interested in this new Sigma,

Your review of this lens is greatly appreciated! Your astrophotography experience is 2nd to none!

Simply stunning. When moved to full frame I jumped from Panasonic to Sony due to the lack of wide -> normal FOV astro suitable options in the L-mount line up. Sigma has very much put L-mount back on the radar as a really serious contender for widefield astro. As a Sony shooter, a big thank you goes to Sigma. I think Sony, Nikon and Panasonic are now all really viable mirrorless systems for astro, which is not something you could've said pre covid.

I've used some wide angle lenses and this is the first time I see good star shapes in the corners. Good job Sigma and thank you Nico for the detailed review! 👍👍

This was super helpful to watch as I'm going to be in the market for an ultra wide angle lens soon. Previously, the Sony 14mm f/1.8 GM was a sure bet but this absolutely makes me want the Sigma now. It's truly wild how well it performs in the corners for being 14mm and f/1.4, which is a combo we haven't seen in modern lenses before. Great work Nico.

Tough choice there since they are around the same price, and both look to be pretty big improvements on the Sigma 14mm f/1.8 DG HSM. Without actually having used the Sony lens, it looks like the main thing it has going for it is the much lower size and weight. From the photo samples I've seen online, it looks like it has more distortion and CA (?) than this new Sigma 14mm when both are at f/1.8. I didn't notice any visible CA on my copy of this Sigma 14mm f/1.4. I see other reviewers noted it had some, but they all used close-up objects to test. I am also a BIG fan of the collar/foot they put on this lens. It's much easier than some of the 3rd-party solutions I've seen for easy framing with a big lens on a star tracker.

Sigma doesn’t have the rights to release on Nikons or canons new mount as of yet.

Nico, great review as always. The focus by wire is understandable these days for video, nikon are doing a new thing where they allow a linear option in the menu. Thus, I hope this comes to Z mount, and I hope that becomes an option.

Another key note with modern focus by wire systems. They enable a linear focus option, which then allows the user to extend the focus throw well beyond what is typical in still lenses for super fine control. Those of us who shoot cine lenses know already how much more control you have with focus throws of 270 degrees or more, and with focus by wire you can go well beyond this rotation depending on the camera and the lens. For astro photography this makes getting that pin point focus so much easier than futzing with typical rapid-throw stills lenses.

Very interesting point! I look forward to seeing what the camera manufacturers can do with the focus system being more 'software-based' now.

Nico, great analysis. can i suggest a subject for video: stars trackers? because there are several models... some for cheap, others much more expensive, there is a pro version, pro pack, ioptron skyguider pro, skytracker, ioptron pro with polar. What really changes in these versions, advantages and disadvantages. I haven't found a video like that yet. Thanks.

FYI the MEGADAP ETZ21 adapter allows you to mount Sony E-mount lenses (including the Sigma DG DN lenses) on Nikon Z complete with autofocus.

7:44 yeah thats also a reason why i mostly use autofocus. There are some exceptions though like the Sony 90mm macro which does have endstops.

Hey Nico! The lens looks great in performance, but that focus-by-wire really kills my plans to pair it with a dedicated astro camera, like the 2600mc. Any other specific points you would consider to watch out for, when looking at such pairing?

Like you said, don't hold your breath for a DSLR version, but I'd love to add this to my 3 Sigma Art primes, 20, 35, 50. I love these! Maybe the 14mm, 1.8 will end up available used at a good price now...hmm

Hey Nico, I don't follow Sony equipment but Richard at Nightscape Images uses the MEGADAP Adaptor for Sony Lenses to Nikon Z 6ii. The adaptor works well for him !

Hi Nico I have a canon DSLR so this isnt for me however just a question could you use this lens with a ASI camera? thanks

That's very impressive. Hopefully the HSM version will get a lot cheaper now that this is out. I still shoot on dslr cameras so that would be great news for me.

Thanks Nico for the detailed review. Did you get a chance to review the Sony 14mm GM lens? It's much lighter, much better IQ vs the Sigma 1.8, my old Sigma copy (EF mount) was sold soon after I got the GM lens... IMHO it's a tough to swap out the Sony with this newer, yet much bigger lens, even with better image quality and the nice tripod ring.

This was fun to watch

Great review! I've been holding off getting the 1.8 version in the hopes that a 1.4 version might come out, so this feels like my prayer was answered. The manual aperture control ring is a huge plus as well!

Do I have time to update my list for Santa? This lens looks amazing. Thanks for the thorough review Nico!

That decision is unfortunately in Nikon’s hands. They’ve been very miserly about licensing 3rd party lenses for Z mount, albeit not quite as bad as Canon with RF :-/

What are the differences between each type of mount? And what are f stops? Also, I want to do deep sky astrophotography not landscape or milky way, this means I should not opt for a wide angle lens right?

I have the Samyang 14mm. It's so wide it's difficult to use for anything else. I used it on a huge cliff and I had to stand right up close to the cliff. Must be even wider on full frame.

Hi, you've inspired me a lot getting in to astro as a beginner. My first lens is Samyang 12/2. But here in Sweden it's too light during night. I'm waiting for the fall.... This lens look stunning. But how is this compared to Sigma 16/1.4? Not much difference in numbers, but maybe in optics. But much cheaper for a beginner.

@stevenneaves8079

Well the 16mm 1.4 only covers APS-C, is not nearly as durable, and lacks more recent optical improvements for higher resolution sensors. For a beginner just getting something wide angle would be the best place to start. This lens is really the final boss of wide angle lenses, not something most beginners would be looking at

Nico did you review the Viltrox 16mm yet? It’s a 1/3 the price of this beast and can take filters.

I was hoping Sigma would announce that this lens would also be made for Nikon Z-mount (alongside Sony E & the L-mount). I guess the MegaDap ETZ21 adapter is in my near future...bc I don't see Sigma debuting the Z-mount 20/1.4 DG DN Art anytime soon either.

There's a working EtoZ adapter u would be able to use it on Nikon Z mount

I have the sigma 14mm f/1.8. Do you think I should go for the new f/1.4?

A good review but a missed opportunity to compare with other brands. You mentioned the Sony 14GM and comparison images with that lens would really make this review much more usefull. Just my 2 cts! Bob

Hello Nico, I hear such beautiful things about Sigma making their lenses more astrophotography friendly. I cannot understand why they do not have it for Nikon Z. It seems impossible because of the "short focal flange distance.." Therefore, should we focus on Nikon Z lenses or Sigma Art for the Nikon F with an FTZ adapter for us Nikon Z users?

Is the focus lock a mechanical or electronic lock? If you set a proper focus then turn the camera off, walk around a few days, and set up for a shot.. will the focus still be correct?

@NebulaPhotos

Жыл бұрын

I've sent the lens back, but the focus position does not seem to move once you've activated the lock. What you are suggesting may work if you didn't remove the lens from the camera, as I don't believe it resets on power off/on. For example, when I switched batteries, I had the manual focus lock on, and the focus position was still correct after I turned the camera back on. That said, keep in mind that focus position can change based on temperature since metal and glass will slightly contract/expand with temp. changes, and this can throw off focus even if the position of the glass elements to sensor hasn't changed through your manual intervention. The faster the f/ratio the smaller the critical zone of focus, and more likely a temperature swing will throw the system out of focus.

I've been using this lens for a while, for astro and extreme wide angle shots

Great comparison. Haven't had time to check, have you any Tamron reviews? Yes or no will suffice, I'll look into it when I actually have time to watch. I have a Tamron 35mm f/1.4 and would love to see what someone who knows what they're doing can accomplish with it. :D

Great review! What about the Sigma fp-L? How did it perform?

@NebulaPhotos

Жыл бұрын

It's a very good sensor for astrophotography, and it seems that Sigma offers a true 'raw' - no noise filtering, which is what astrophotographers typically want. As for the camera design, since the screen is fixed, the EVF is basically necessary unless you are willing to mod the screen to make it a flip screen. Otherwise, you will find yourself lying on the ground to frame and focus for astro. Battery life isn't great, but solutions are available for that. Software support is weak/ non-existent, so I use an intervalometer rather than a tethered laptop. I own the Sigma fp and for my style of astrophotography, I prefer the fp to the fp-L, but the fp-L is better for optical testing because the smaller pixels are less forgiving making it better for showing differences between two lenses like I was doing in this video. Other than the sensor, the cameras are basically identical. Definitely quirky, but if you don't mind working with a quirky camera, they produce very nice results.

I talk about this for a bit in the middle of the video.

Yes, this is a new design for mirrorless cameras only. Canon EF mount is for Canon SLR and DSLR (cameras with a flip-up mirror). Designing a lens specifically for mirrorless cameras offers new opportunities because of the shorter focal flange distance. This means the rear glass elements can be about 24mm closer to the sensor since they don't have to accommodate the flip-up mirror in a DSLR. That allows for more complex designs that offer better correction and faster optics. I don't expect Sigma will be making any new lens designs for Canon EF. We all hope Sigma will be able to make lenses for the Canon RF mount, but so far Canon hasn't allowed for 3rd-party autofocus lenses on the R system.

Often times, you hit multiple points and answer the questions that I have that arise as I am watching your videos. His skip over the questions he purports to address. I also concede your instruction isn't for everyone and his is probably spot on for them. I also watched all 8 hours of you critiquing other astro photos. I love that you invested the time to provide meaningful feedback to them all. Since you didn't ask, the only thing about your videos I would change is your rate of speech. I play them at 2x and still often times find them to be slow. But, I also listen to my audiobooks at 2.6x so its probably a me problem.

if the focus system could just focus on the pin points of light, there is no need for anything fancy on the lens. I've only seen Olympus do starry sky AF properly. All the big companies just stay in their lane and never innovate unless pushed.

Good point. And I have found I can actually use the touch autofocus on many mirrorless cameras on the stars already. The issue is reliability and time wasted if it's hunting. Have you tried the Olympus system. I've seen some of the reviews, but they didn't answer all my questions about it.

Thanks for the review. Interesting but I think I'll stay with my 14-24 Nikon 2.8. I can fix my wonky stars with one click of a button in SIRIL. SIRIL is free and I get to keep the $1000.00+ in my pocket.

f/1.4 is 4x the amount of light that the 14-24 f/2.8 lets in, though. The difference is much more than the star shapes.

I think the bat wings in the corners of the f/1.8 lens is due to comatic aberration, not astigmatism. Did you try the Sigma 15 mm f/1.4 DG:DN Art lens?

@@NebulaPhotos Thank you Nico. The 15 is a cool lens, but 15 f/1.4 DG DN Art looks even more impressive for astrophotography, and seems to be well worth the price. In the other video, the 14 seems to have more field curvature than the 15. The 14 should have had a wider field of view, but doesn’t. Is that truly due to its optics and field stops, or is the Sigma camera pre-processing the data (it must know which lens is attached to it)? I have 4 Leica mirrorless digital cameras, and AFAIK, they do in-camera correction to some of the lenses (if they are 6-bit coded M mount lenses or electronically encoded L-mount lenses).

A big improvement from the old one for sure. But for Sony, not a single reason to buy this over the 14GM.

Two thirds of a stop of light, as well as the mf ring lock feature. I wish the Sony 20/1,8G had that.. this Sigma is 200e more expensive than the GM here though

​@@Vantrakter In these samples, even the center stars look like plus signs until f/2.8. Kind of defeats the point of being the fastest ultrawide astro lens if you have to stop down two stops to get tolerable stars. And if you're on a tracker, you'd be shooting at f/4 or smaller anyway. It's a focus-by-wire lens; the MF ring doesn't do anything if it's in AF mode. Disable shutter focus, and you got your focus lock on any lens. No need for gimmicky focus lock switches. ;)

I have both (did have 2 of the GM). The Sigma trounces the Sony for astro, it's not even close.

Any Askar 151PHQ reviews in the works?

Not in the works currently, but I'll consider it, maybe later in the summer - I think I need a break from reviewing optics for a couple months. :)

WOW.... amazing lens. But amazing cost. Maybe one day. But for someone starting in astrophotograhy, not yet.

This lens looks very nice, but I'm staying with my Sony 20mm f 1.8

Good stuff but too rich for my blood. That's almost 3/4 of the cost of an AM5 mount

I like how they left out canon

If Nikon ever makes a fixed 14mm it will destroy that Sigma in the corners and in general iq like it did with all other competitors because of the flange distance on its huge mount. Otherwise, well done for Sigma, but I'm personally waiting for the Nikon version!

"If Nikon ever makes a fixed 14mm it will destroy that Sigma in the corners" I wouldn't bet on it. Nikon's fast aperture lenses have rarely been class leading. Sony has been killing it lately with their fast primes. And yes, I'm a Nikon, Sony and Sigma shooter.

The Z mounts flange distance is shorter and a full autofocus capable adapter exists from e-mount to z-mount so there is an option for Nikon.

It can easily be adapted to Z-Mount, and for a lens like this, I think there are no downsides, other than the cost of the adapter. I wouldn't be surprised if Sony got an exclusivity deal for full frame lenses with Sigma.
