Nex5N vs Nex5R
I had a 5N and the AF was totally unreliable in lower light. For instance, about 50% of my pictures, using AF, at my daughters graduation focused on people way behind her and her friends. VERY annoying! Sold it on Ebay.
The 5N gives great quality when you want to spend time, but as a point and shooter, it sux. I would go for the 5R. Hopefully it is an improvement.
