I've been banging on about buying an NEX 6 body to use along side my beloved 5N, but, I am beginning to ask myself, do I need to? Having read a few reviews, I'm wondering, what actually is the difference other than the obvious features: EVF. Yep, could be a bonus point, but not crucial. Pop up flash. Again, could be useful for a bit of fill in. Mode dial. Not really. WiFi. Absolutely no use to me at all. JPEG improvements. Only shoot Raw. PDAF(?). Doesn't work with Sigma(?) not sure if I am right on that point. Given the addition of the EVF and flash, I would buy this camera if it had an upgraded sensor over the 5N, but I don't think it has. Please tell me if I'm wrong. I haven't so far found any mention of this in reviews. Any 5N users finding any kind of improvement with the 6? Before someone suggests it, I don't want the 7. Too many pixels for what I do. Rich.
