@Rob-F, thanks for the response, I might look into the v4. Interesting thoughts about the v2/3 - are they the same formula?If I had it my way I'd get a v1 in black. But I ain't going to spend that kind of money!
@Chromacomaphoto, having both is not really an option - I could never decide which to take! And I love the look of the summilux pre-asph shots, if it went closer it'd be perfect! It is a special lens. If I was a two lens person I'd buy a CV 35/1.7 and keep the summilux for most of my shots. But I'm not.
@Ko.Fe, except at f/2! 0.65 is problematic as I'd be flying blind from 0.7m, also not interested in goggled lenses. You bring up an interesting point though regarding image quality, I feel they're all good enough and I know that I'm the weak link in the system!
@raid, 2 reasons. First is $ - I'd prefer to not have money (that I don't really have) tied up in lenses. I have a young family and collecting lenses (as much as it'd be fun) isn't high on my priority list. The second reason is I'm a one lens kinda person. I like the simplicity of just picking up my camera and going, no deciding. If I had both I'd forever be wishing I'd taken the other one.
@mdarnton, interesting. You don't always hear good things about the v3. know I'll miss the extra stop, but at the moment I miss the MFD more...
