Nick has been shooting with a Leica Summarit-M 35mm f/2.5 for the last two years since he dove deep into the Leica world with his M Typ 240 rangefinder. But when he discovered the newer Voigtländer 35mm f/1.7 Ultron Aspherical, he was keen to grab it as an alternative to the very, very expensive 35mm Summilux F1.4 by Leica.
As you can see, the images are very sharp even wide open, though there is noticeable vignetting from F1.7 to roughly F4. Beyond that it is supremely sharp and clear across the board.
Nick has since started shooting the lens on his new Leica M7 film rangefinder so we'll update this post when he has some of the results developed and scanned!
