35mm · f/3.5
The Isco-Gottingen Westron 35mm f/3.5 (RF) is praised for its pleasing rendering and good bokeh, with some users noting a Leica-like 3D feel (RioRico). However, opinions on Isco glass are mixed, as many speak unkindly of it (RioRico). Build includes 13 iris blades and 54mm front threads, weighing 250g. It suits photographers seeking a compact, characterful wide-angle for manual focus systems, especially those who appreciate unique rendering over absolute sharpness.
