It's nice. Coming from a C3 there are a few things I noticed right away. The 5n feels lighter than the C3 did. The larger grip is nice and it feels like it sits in the hand a tiny bit better. The UI is a bit different and I swear the image on the LCD looks bigger but I can't see why that would be as they are the same size. The extra features (like AEL and the ability to attach the Sony EVF) are welcome and I'm happy to have 1080p video. Overall I'm pleased with the upgrade. Now if the battery would just finish charging so I can play with it some more.
