What's wrong with the GF2?
It's a great camera. I just want to try something different and, objectively, better. After seeing the depth of pictures from my friend's Nikon DSLR, I've decided to step it up a little bit more. While I can take great photos with the GF2, I still want better. I've heard nothing but great things about the nex.
I believe I'm a fairly good photographer so I won't consider it lack of skill with the instrument. Just want to try something different.
