Hello to you all. I am new to the m43 world. For several months I have Panasonic G1 with Minolta adapter and Minolta Rokkor QF 50/3.5 macro and I am very pleasantly surprised by this combination With the Panasonic G1 currently have Pentax K7 and I am in great dilemma. Sell all Pentax equipment and move on m43 (OM-D with 12-50, 45/1.8 and 20/1.7) or change K7 for K5. Sorry for the bad writing, but I hope that is understandable.
