I'm probably making two huge mistakes here, the first being the ordering of a GF-1/20mm kit (and thus the inauguration of a third camera system in my drawer), and the second being signing up for this forum, as I already spend way too much time talking about photography on the internet. but, in for a dime, in for a dollar!
I'm quite excited about the GF-1, as I love the idea of a pocketable, large(ish)-sensor interchangeable lens camera. And the 20/1.7 seems like a home run.
But I also came on board interested in adapters and legacy lenses. I ordered two from eBay--the Leica M (as I am fairly heavily invested in this system for film and have an R-D1) and Pen-F. I also picked up a Pen Zuiko 40/1.4 on eBay.
I was initially kind of excited at the idea of the C-mount stuff, and eagerly perused the coverage chart and bokeh thread today. But I was kind of shocked to see how expensive the full-coverage lenses have already become--and, except for the interesting edge smearing effects and weird bokeh, the 20/1.7 seems to render most of them moot.
My question is this. What other legacy systems are worth adapting to the m4/3 cameras? I use Pentax SLR stuff and have the K-7, so there's no need for me to adapt those--plus, even though they're very small by SLR standards, they're certainly not smaller than the m4/3 autofocus lenses. Leica M and Pen seem to be the ones most worth it--tiny, well-made, and sharp all the way across the frame.
It would be nice to use, say, Robot lenses, or Voigtlander Prominent, or some other, more obscure RF system optics, but there don't seem to be adapters yet. I'm tempted by Amedeo's Contax/Nikon (I have his excellent Contax-Leica and will try out a few things using it), but we'll see.
It seems, then, that Pen and Leica are the sweet spot? Am I missing something?
Thanks for all the great info you guys have posted on here, and with any luck I won't burn up too much of my time here.
