I don't have the CV 35/f1.2, I'm not too interested in fast lenses, but I've followed other people's interest in the version 2 lens; [usual sources], LUF. RangeFinderForum, maybe here, maybe Steve Huff. There's a lot of feedback on the lens if you search. I thought that it might be an alternative to the fast '50mm' route, a cropped M9 file to the equivalent of a 40 to 50mm field of view will still deliver a quality file, and could be a better option than some other suggestions. Maybe worth consideration.never thought of that! do u have an image sample?
Another, far cheaper alternative is to stick with your Summarit, and buy yourself a Manfrotto 685B monopod. It's super fast to use [check it out - Michael Reichman video-reviewed it on Luminous Landscape]. But don't use it to balance the camera on, rack it out so you can jam it in your armpit; heavily lean into it, making it and you a more stable 'tripod' platform for more stable hand-held shooting. That's how I often work in windy weather on rocky ground. [Hand-holding whilst leaning on a fast-erecting tripod also works well when there isn't time to set a camera properly on the tripod ------- try it, you'll be surprised at how stable your Summarit will become......]. Oh yes, make sure the tripod comes up to your [wait for it] ....................... armpit.
Good luck.
