ILCE-7S Focal Length: unknown Aperture: f/1.0 Exposure Time: 1/25 sec ISO: 400 04/21/15 Sony Alpha A7s - Voigtlaender Ultron 35 f1.7This lens should apparently be one of the best lenses produced by Voigtländer. From my experience with my example, I can't really confirm that. I may have bought a lemon, it happens.
Extremely difficult to focus at f1.7 or near to that even with the focus peaking function on the Sony cameras. I can't even say that it's very sharp wide open, you would have to stop down quite a bit to get it sharp from corner to corner. With my example I'm talking f11 or thereabouts. Not exactly ideal in low light situations. Again, this lens performs best on APS-C sensors for obvious reasons. It's actually very decent on M43 cameras but that sensor is even smaller.
It's not a lens that I will be using often and I might find myself passing it on to someone and I have a few more 35mm lenses that perform a lot better on these full frame cameras like the native Sonnar T* FE 35 f2.8 ZA which is one heck of a lens. 1338
ILCE-7S Focal Length: unknown Aperture: f/1.0 Exposure Time: 1/100 sec ISO: 160 01/14/13 Manual Focus LensesA side view of the Heliar, Ultron and Nokton lenses I posted yesterday. Some of you might have been wondering what they really look like. That Nokton does seem fat doesn't it, but only because the other two are really slim...really. I might just post some images of these lenses mounted on the Nex or E-PL1 cameras just so that you can see how small they are. The Nokton is the heaviest of the 3 lenses and is one of my favourite lenses. 1233

01/13/13 Manual Focus LensesAfter a little sorting I realized that I have some nice Voigtländer lenses the some of you might not know about. The first 3 are the Heliar 75 f2.5, the Ultron 35 f1.7 and the Nokton 50 f1.5. I've shown a number of images from the 75 and the 50 and I use then quite a bit on both the Nex and m4/3 cameras. The 35 I don't use a lot and I'll explain why in the next couple of days. Most of these lenses cannot be bought new anymore because they just don't make them. They have been superceeded by newer models but that doesn't mean that the newer ones are better than these models here. Both the 75 and 50 perform very well on the Nex and having fokus peeking is a major plus on these cameras. I use my E-PL1 mostly for manual focus lenses in the m4/3 camp because I find it easier to focus than on the other models. 1193

03/18/12 Voigtlaender Ultron 35 f1.7Another very good lens (if you can find one) is the now discontinued Voigtländer 35 f1.7. Much smaller than the Nokton 35 f1.2 and much lighter. Mine is in silver and looks pretty good. I'm not certain if you can get them in black, but that doesn't bother me at all. Again this image way converted with Nik SFX2. 1863
