I had the ultron 35/1.7 II and hated the handling.. this one looks much nicer.
the question I'd have regarding focus coupling: does the 0.7/0.58m figures come from the cam actually "ending" at 0.7m? I hated that feature on the f/1.7 lens which went even further.
It always gave me a feeling of uncertainty when focusing close.
why don't they add a removable screw for all those digital shooters?
