Ken: I know that a summicron lies in your future and you will be rewarded for this long period of holding back.

Another vote for 35/75, a combo that seems especially good for photographs of people: close up tight portraits for the 75, environmental portraits for the 35.
If there hadn't been something about 75, I never would have gone back to it, especially since my ZI doesn't even have 75 framelines. But after I sold my first R3A and CV 75/2.5, I always missed that combo. Shooting a 50 on the RD-1 (effective fl = 75) just made it worse.
The cron's advantages are not just speed, but also close focus distance, tonality, and color rendition. I do not find it clinical at all. And it is smaller and much easier to use than the 75/1.4 . But back on earth, the CV 75 is a very sweet option, too. The summarit 75/2.5 is nice, but from a test I saw comparing the summarit, the summicron, and the summilux, I don't think the bokeh is as good and the look is too clinical for portraits (I'd prefer the softness of the CV lens), and there is almost no chance of getting one used. So between the price of a new summarit and a used summicron, I would vote for saving up for the summicron.
