Church Wall, 2003 -- Canon 300D Rebel & EF 80-200mm f2.8L.
I had two third party batteries I bought when I had the NEX-5 and never used them on the new NEX-5N since the battery life has improved quite a bit on this new camera and never exhausted it in any one take. Today I just tried them on the NEX-5N and the camera complained about Incompatible Battery error. Frankly I was a little pissed off. Like what Panasonic did with their chipped batteries, this is just pure greed. If they price their batteries at reasonable level, few would buy third party batteries.
