​@@AminTheMystic I should have elaborated. It is not an unfair comparison, It is not unfair because the pixel density is actually higher on the A6500. Also, the sharpness of the lens is probably far lower than even the A6500. The effective sharpness of many older lenses are far under 10Mpix. It dominates sharpness, and the megapixels don't contribute to lens sharpness. Having a speedbooster with glass elements in between will always result in worse quality, and you can see that. Most of the gripes and optical defects you can see in the video have nothing to do with lower resolution. If anything, they would be exacerbated with a higher resolution (ex. chromatic aberration). However, in light of making things 'fair' he should have down-scaled the result to a similar resolution just for comparisons sake. Again, it wouldnt make the A6500 look better, but probably a bit worse in comparison.

So happy you finally got a full frame Sony. Some of your earlier videos I was wondering how certain lenses would look on a FF.

Very interesting results, great video!

One of the reasons you're getting more chromatic aberration in every speed boosted shot it shat the speed booster is adding a stop of light. While there is more glass the big cause of the difference is that you are effectively comparing one stop brighter. In the A6500 shots you have stepped down the camera with iso and exposure time. Always remember it's not just chainging the focal length but also the amount of light hitting the sensor.

@ChristopherBurress

+Alexander Somma I'm not sure that a slower shutter speed would help much with the chromatic aberrations. Without the speed booster there was zero CA, a brighter exposure isn't going to cause it to show up. I think it was more of just poorly corrected lenses within the speedbooster

+Dan G yes that's the point of the speedbooster. It removes the crop factor.

Nice! I hope you can get a few focal reducers to see how their glass fares against full frame as well.

Thank you for the great review. I have a7m2 and fuji x-a10. I also like to use Minolta md 50.4 lens. However, for the portrait picture, I tend to prefer using x-a10 with speed-booster than using a7m2. Possibly because the picture get softer when you use speed-booster and soft image could give a better feeling for the portrait picture.

Thanks for the solid review 👊

Hey Chris, nice test. I wish the color temperature was matched for the test. I think that might change something about the CA? I did the exact same test but with a Canon FD, and their was actually less chronic abberation with the speedbooster. Photos also came out sharper. I wonder if different lenses behave differently with the speedbooster. Cheers

Great comparison, still on the trees part but I wonder if it's not different focus between the images since at F11 the speedboster appears as sharp

I started using the Zhongyi lens turbo v1 aboit 5 years ago on a Nex5n body with canon fd lenses. And am very fond of it. This year upgraded my body to the A6500 aswell as the adapter to the v2. I have had a try with other cheap speedboosters from ebay and have to say, get the Zhongyi v2. Its the best of the cheap metabones copies. Cool thing too is, if you get a dummy adapter, you actually have 2 focal ranges with one lens. For example my telephoto lens, the canon fd 80-200 f4, becomes a 120-300mm with dummy adapter, bit if i need less focal distance, i use the lens turbo. And only have to carry 1 lens.

I bite the bullet and bought one not for my Minolta lens but for my Canon FD lenses. I have to say, it works out pretty good. I notice right away the wider FOV, creamier bokeh, faster shutter speeds and lower ISO. It didn't look like it took a quality drop to my lenses but with more glass elements in the light path, there's got to be some loss or sacrifice somewhere. There is no free lunch, like they say...but I enjoy the added benefits of the focal reducer more than pixel peeping my images.

Great video. I also own Lens Turbo II and have few more tips (+ for pros and - for cons): + adds least one stop of light; + adds a lot of center sharpness on slow lenses; - field curviture on wide ange lenses; - chromatic abberation; - not good for fast apertures. It should be around f/2 or slower; - lens dependent (some lens is quite sharp and some of them not); My Rikenon 50mm f/2 was not quite sharp wide open with dummy adapter. On Lens Turbo it's razor sharp in center even on f/2. Anyway such setup much smaller than fullframe camera.

@BS-bd5uq

5 жыл бұрын

The reason why it's sharp in center with Lens Turbo is that it effectively "cramped" the optical frequencies to the center. That being said, the "extra" sharpness you get using Lens Turbo equals reducing your resolution without Lens Turbo by the same ratio. It effectively turns a lens-bound resolution into a sensor-bound one + wider FOV + brighter image + loss of resolution through extra lenses. As a result, you are not actually getting more information.

Hey Chris, this is the most specific review ive wanted to watch abt speedbooster, but im more on video so some of this helps a lot. u might want to try the Viltrox EF-E version 2 (ads says it has CDAF and PDAF switch for af)

+Amir Azlan I would like to do that. Gonna have to get my hands on some speedboosters!

Does using a speedbooster (AKA Focal Reducer) on a APS-C camera really make much of a difference to your field of view? I know it's a huge difference with Micro 4/3rds. The Metabones XL can get near an APS-H field of view on m43. I tested a Sigma 17-50 f2.8 which is f2.0 with the Metabones. It performed surprisingly well and only noticed slight chromatic aberrations in high contrast areas. Which could have been more due to the lens and wide open aperture. Flaring was fairly prevalent shooting at the sun as well but not bad. You'd expect at least some with added glass in front of the sensor. But again... I have not tested the Sigma on a native APS-C body as I don't have one. But obviously different mounts and camera bodies could vary alot in the results. Mine was a m43 to Canon EF Metabones mount. The XL version gives significant vignetting with APS-C lenses and the Ultra version is better with vignetting due to the narrower field of view. Of course Full Frame lenses have no problem with Vignetting because it's a cropped view.

Now that you have a full frame sony i'd love to see more vids on it! You make great aps-c vids!

Great Video!!! Including the dust in the bokah balls. I Always wanted to know how my vintedge lenses would look on a full frame without the Lens Turbo II and now i know. Thanks a lot.

I would be careful about using the term, "Speedbooster." I think that is a product name rather than a type of product. "Focal Reducer" would be a more appropriate moniker as it applies to a whole range of adapters that utilize optical elements in order to reduce the lens's image circle. I have a copy of the Zhongyi Lens Turbo II for adapting M42 lenses to my m43 OM-D E-M1. and it certainly offers a unique image quality which can be quite compelling and attractive. Thanks for your comparison of focal reducers versus 35mm sensors. The results were quite interesting.

Your video's are getting better each time. Thanks for all the info. I have a question about OSS and IBIS which might be input for a video. Does the Sigma 30mm 1.4 works just as well as the SEL35F18 (with OSS) on an IBIS e mount body (A6500)? Is it just as stabilized with the sigma or does the OSS of the sony really adds to the IBIS?

+Daryl Oeben the ibis is really really good for photos, if you are just holding the camera with video it's good, if you are walking its bad. The oss definitely adds a lot to the stability, but it still isn't going to be enough for lots of video. You can maybe use some Peter McKinnon tricks to get some smoother slow mo stuff. But in general the difference between nothing and ibis is huge for getting real usable shots, the difference between ibis and oss and getting a usable shot is significantly less of a jump. I think you will make your decision more on image quality and autofocus speeds.

Here is what a lot of people in the comment section do no get. Even if the both camera's where 24mp the full frame would still produce better quality images zoomed in simply because it has larger pixels on the sensor itself whereas the cropped sensor has smaller pixels which SIMPLY means that the full frame will always no matter what producer cleaner images and more natural looking pictures because it's pixels collect more light information to pair with it's resolution even if it is the same as the cropped sensor. All a speedbooster does is focus the light onto the sensor like what a full frame would. It only mimics the larger sensor and doesn't in any way make the cropped sensor full frame AT ALL.

You'd need a speed booster for the lens mount. I don't know of any medium format lenses that will fit on the minolta speed booster. The speed booster also works by focusing the image circle. The circle made by most are for apsc or m43. That is, unless you get one specifically for full frame, which would require medium format lenses. Some 35mm lenses may project a circle large enough to fill a speed booster for full frame. But then, what's the point? You're just adding glass to an image circle that's already large enough to cover the sensor.

@NaviRetlav

Mat had only the lens mount converter from sony lens to h mount body, no glass in it, that's why he get the super nice depth of field with that otus lens since most of the hasselblad lenses are not that wide open as otus. Sadly It might be true that speedbooster might be cutting out the side areas of the lens. You probably could test that out by adding the paper "frame" to the speedbooster between your lens, and if that frame shape will show up in the images, that means it's the booster limit, if it doesn't that means that the the frame is on the dark part that lens doesn't project :) Anyway, I'm waiting for your test results, hopefully it's all just lenses image circle size, what would be the main reason for me to finally get the A7 RII ;)

In theory, it would be a waste of time, and you're better off not trying unless you already have the gear lying around.
