Hi!
After my first tests of the Russar on A7, I decided to give it an opportunity to shine.
This lens, like many RF wide angle, performs quite bad on modern sensor (actualy the only FF camera that can use the Russar is the A7... oh and Leica), because light rays arrive with a too hard angle on the border of the sensor (basicaly said).
So, I expected better results on border (less vignetting) on film.
Well, it was way better than what I expected! It's really another lens on film! After seeing film, we understand better that this design was especialy made to avoid the problem of darker corners on the edges (vigneting).
My scanner was quite dirty, and it's not top-end scanner, so sharpness can't be really judged here (but sharpness is good on A7!)

Interesting.
That can explain too why there can be some problems on using a 2,8/3,5cm Jup/Biogon on a A7.
I am in a hurry to finish my home made "photosniper" to shoot with a film... |

Hi,
Very nice shots ! Actually I like the Russar a lot. It is an excellent lens even if its max aperture is limited, despite (or thanks to ?) which, however, it remains quite good wide open, even in the edges/corners.
The following shot was made with my "red-lettered" Zorki 5 on Fuji Provia 100 film. The blow-up of the bits of ice on the frozen canal, detail of the same picture, shows that it is indeed really sharp. And because of the low sunset light and the Iso 100, this was taken handheld (strangely enough I do not always carry a tripod when walking out of home :-) ) wide open (F5.6) at 1/20th of a second.
Congratulations to Russian engineers !

This is a...Russar design :) . The Russar is one of the rare design that is known to have been made first by soviets (Russinov).
D-KLIK, interesting, are you living next to Fontainebleau?

Hello,
Yes I do live in Fontainebleau quite close to where the shot was made, which is where I generally test my "old stuff" !
Another "first by Russians" was the pre-war Fed 2,8cm, which was an F4.5 whereas the Germans at the time were F6.3, and included a lens which was less than 1mm thick.

Interesting, then we are almost neighbors.
Yes about the FED 28/4.5. There is a very interesting article about it made by Marco Cavina : http://www.marcocavina.com/articoli_fotografici/FED_35_28mm_4,5/00_pag.htm |
