NX20 Wifi, etc
Got my NX20 to accompany my NX200, but am disappointed by Wifi useful for uploading only small files. That's pretty useless for a camera that shoots RAW. It's a comfortable camera to use, but I guess I should have downloaded the manual and read it. Also, it seems that I sometimes inadvertently press some button, perhaps the 'Fn' and it won't focus. Anybody done that and can explain why? The standard 18-55 zoom is very prone to blue fringing on trees, of course.
