I've had my Viewty for about 3 month now and the camera is very very good in good light, in low light its not as good as a K800i but if you alter the settings and use all the functions like adjustable iso, manual focus and what not then you can get amazing results in all lighting conditions. Its not a camera phone for the amatuer is what I'd say, its for folk who know a bit about cameras.
Heres some shots I took:
As you can see, its certainly not a poor camera phone at all, just need to know how to use it. The video quality is amazing tho in all conditions, really fantastic.
If your interested also, the Viewty is being hacked by folk and theres additional functions been found not implemented on the phone, such as face recognition and higher quality settings, these I believe are whats being sold on a new Viewty due for sale later this year but are actually in the original Viewty just not added to the normal menus.
