Has anyone used this on :43: ? While not as fast as the Panasonic 20 (much less the PL 1.4 ) it is also cheaper. OTOH, there is need for a MMF-1 or MMF-2 4/3->:43: adaptor. I'm an old normal prime shooter. 90% of my photographs have probably been taken with a normal prime - 50mm on 35, 75mm on 6x6, etc. This lens looks interesting to me as a result. I've searched but my google-fu is quite weak here and I get almost as many "not found" results as when I tried to research a VF-3. Thanks!
