It is great to see it available in one of the most versatile and adaptable mounts with a filter thread. I've been impressed by voigtlanders modern lenses and I'm sure for video the nokton is great! There aren't too many ultra fast 21mm lenses out there so it's much appreciated.

I have used the ultron on my m9 and it is also dramatic and lets you get some low light shots with deep-focus. The images are very sharp and when I used it on my a7s with close focus adapter you can get some pretty wild closeups!

Gayyy

Voigtlanders 21mm offerings are great KZfaq lenses when adapted to mirror less. The focal length and ability to focus close is great! Sony's own wide angle fast primes are stiff competition though because even at 20mm~24mm wide open still needs focus tracking for a talking head segment

Thank you very much! I’m glad you liked the video and I actually have a very interesting 21mm lens video coming up soon! Should be done by the end of the month. A fantastic compact option for rangefinders and a bit of history behind rangefinder ultra wide lenses.

@@TheWholePicture this isn’t the VG 21mm 3.5. I’ve been eyeing that lens for a year or so. I’ll look forward to your videos mate. Any recommendations let me know. Cheers

I think it should be a good lens to add to the kit you have! For Sony users it may be the right choice, but for me I use a variety of cameras so the Ultron suits my style.　コメントありがとうございました。広角、絞り明るいレンズはとても珍しくてフォクトレンダーはいつもいいレンズ出してますからNokton　21ミリもたのしみですね！

Thank you so much for the comment! I was really happy to hear about the Sony 20mm 1.8. It is at a reasonable price point and the autofocus would be great for youtube and some video work. As for street photography its probably best to use manual focus just in case but it is definitely a welcomed addition!

I'm sure the quality of the summilux is much better though. Of course it comes at a price but I found that all of the modern summilux lenses are extremely sharp and render great images even at f1.4. With voigtlander lenses it can be hit or miss and I even found the light transmission from the f1.8 at 1.8 was similar to the light transmission from my contax biogon 21mm wide open at 2.8... but of course the voigtlanders are good value for money haha

@@TheWholePicture I use the 21mm accessory viewfinder that came with my 21mm f/2.8 Zeiss Biogon on my 21mm Summilux.

It's a great finder! Really roomy and never had any flare issues. I'm going to try to get around to some more leica reviews when I have time.

Hello! Thank you for the comment. 600 USD is a great price for the ultron! Performance in the extreme corners is slightly worse than the center for sure, especially at f/1.8. For my use it isnt a problem and its difficult to see the issues without first zooming in to the photo. The issue is typically blurred corners for the foreground but for the background things tend to stay sharp. Then again shooting at f/1.8 even on 21mm can leave things blurry so I do try to hit the focus as accurately as I can! Unfortunately I dont have any charts but if you have any other questions ill try to answer them!

SHOOT FILM NOT GUNS thank your for your reply,... Yes, I intend to use it at 1.8 but going to Europe soon so for panoramic, cathedrals etc I will be on F8 or 11, so at those aperture it does well?

No problem! I think the performance at 1.8 is very acceptable at night or dark places where any loss in quality is more difficult to perceive. If you are stitching panoramas then maybe cropping in a little bit could help in the corners. It does tend to vignette at f/1.8 but at f/8 and 11 the performance is very good. I would say the only thing is the starbursts, they are very apparent in street lights and other sources of bright light. At f/8 and 11 the star it produces is very defined and so it is a unique look for sure but if its not something you are interested in it may be difficult to avoid. But in general the performance at smaller apertures is quite good.

Thank you for the information! I'm sure it will be a technically impressive lens and hopefully I can do a proper comparison between the two.

Thank you very much for the comment! It's a really high quality lens for the price, only downside i would say is the manual focus but in something this wide i didn't find it much of an issue

@@TheWholePicture I prefer manual focus, using focus magnifier on a function button is so clutch with sonys. had one question, the adapter is a e to m just dummy one, assuming. so on a full frame is it still a 21mm? how much does that conversion effect focal length with leica m lenses ?

Hey no problem, a lenses focal length doesn't change regardless of what camera you use it on it the size of the sensor that would affect that. There may be some small differences in sensor hight and width on M bodies and sony bodies but it shouldn't affect the angle of view. I use the voigtlander close focus adapter and it's really good with this lens, let's you get in really close when you need it!

or i think its called a speed boosted, adapter with correcting glass

I see, yeah unfortunately there is no way to use a focal reducer for m mount lenses, the flange distance doesn't allow for any extra glass and many lenses have glass protruding into the body. If you get a full frame sony youll get the full frame look from the lenses! I still use the original a7s and I love the first generations size with small film lenses, it might be something you'd be interested in too since you have those lenses.

Hello and thank you for the comment. I think in the end I just wanted to talk about the Ultron and thought that this comparison would be timely but it is admittedly click-baity and cannot come to anything conclusive without the other lens. I should have kept the review more focused, say for Leica users, but I'm still trying different formats and seeing what works. Thank you for the suggestions, I will take them into account going forward.

Tell me. Which are those reasons? Looks like you don’t know very well what adapting M Mount lenses or any other vintage glass is. Almost to the point that you can buy a better performing vintage glass or new design for adapting at lower price tag while the actual native similar alternatives could be as x2-x10 times more expensives. That is the case with Pancolar 50mm 1.8, Flektogon 35mm f2.8, or Elmarit R 90mm f2.8 on cheap side at vintage and VM Nokton 35mm f1.2, Summicron M ASPH 50mm f2, or APO Planar 85mm f1.4 on premium modern side. Those are few, but there are tons of examples of glass that modern mounts lack of. Nikkor Noct, Zeiss Otus, Voigtlander Heliar, Leica Summicron, ISCO Cinegon, Voigtlander APO Lanthar, Rollei Apogon... and every single thorium lens. You can’t buy modern thorium lenses due to the rare earth element thorium glass is no longer available in modern consumer products. Adding info to this, those lenses also are offering unique design and performing optic articles with improved performace for many artistic purpose. For example, the yellowing, which is provided by the radiation decay, could act as a built in yellow filter and light transmision reductor, lower than ND 2 which is impressive for product, portrait and every single discipline claiming close focus performance, bokeh quality, or black and white photography. This UNIQUE combo can’t be found today as thorium glass is no longer available and the yellowing process takes several years to increase significantly the goldish saturation of the glass. Under UV exposing period, the glass can be “cleaned” and you can take advantage of the thorium’s excelent dielectric permittivity, which is a strong bonus for shooting wide open withouth experimenting crucial softness as you’ll have with a similar price category more modern lens. For example, the Carl Zeiss Jena Pancolar sold at less than 200€ is certainly similar quality alternative to the Sony Zeiss Sonnar 55mm f1.8 being better at many aspects. Lower price, better all-metal housing, and general performance at sharpness, bokeh, color, contrast, and texture rendering for my taste are similar or better depending the situation. Plus to that, the 1950’s glass is still usable for profesional use as for earning money with photography. Good luck, your Sony cheap-plastic and electronic articles are not going to work 70 years past like all metal will do perfectly. Incomes? Exif data? Fuck that, my clients and I still chose always the total look that the lens is giving instead the minor flaws or lacking features while adapting lenses.
