I can't really help you with the lense, but I did use that camera for a bit. The size is good, it can easily fit in a pocket which is good. If you're doing follow cams and stuff remember to turn off 'Drop Detection' or something like that. It's not great in low light, but for an intro camera, well, it hasn't got all the settings an ideal beginners camera has but it will do. Manual controls are difficult to set quickly because it's all through the screen, but it is a consumer camera so don't expect too much.

, although I did bring my parkinson's with me that day so footy is pretty shakey.
