After watching a review on the NEX-5, I'm seriously debating selling off my camera and switching to one of those. Personally, I love Sony better. And getting a full-frame sensor (Correction: Sensor the same size as the Sony Alpha Cameras) would be great. The one thing that's holding me back is that I just got a 50mm ƒ/1.4 on my EP-1. It would cost more money to get one on an NEX-5, but it would be fully compatible with the camera (manufactured by Sony).
