To those who've already been able to try the Mandler 35 f2 and have experience with Canon 35mm f2 and/or f2.8 LTM:
how does the edge sharpness/field curvature compare? So far I've gathered that the Mandler 35 f2 is very sharp in the center already wide open, so in that regard it would without a doubt be a clear improvement on the Canon 35mm f2.8 LTM which I'm using at the moment. (The Canon 35 2.8 is no slouch, but I am still pining for the Summaron 2.8 which I had to sell many years ago.) But sharpness across the frame: does the Mandler need even more stopping down in order to get decent edge to edge sharpness than the Canon LTM offerings?
