I like my GX1. It's a terrific camera and my PL25 and PL45 are superb lenses. That said, I also like my C3 and in some ways I find the NEX+legacy lenses a bit more satisfying to shoot with. I am not choosing to abandon my GX1 and go all NEX because quite frankly I don't need to. I think they compliment one another quite well. That said, I recently went to the zoo and the museum of flight and both times took the NEX instead of the GX1 forgoing AF and many of the niceties the GX1 brings to the table. Both times I was surprised how well going all MF with the NEX worked out. So I decided to put up my GX1 for the rest of September and go all manual focus on the NEX (meaning no Sigma 30 either). I know I used to do this with my Konica compact RF and Olympus OM cameras but its been a while. It should be fun. I'll come back and post thoughts about it as well as photos.
