I was going to suggest that. I didn't realize if but when I first bought my TP I must have touched the inside lens cover. I had a finger print right on it!

I doubt that is your issue Fabio. My pictures don't have that 'soft edges' look though. My only complaint is the rather lengthy focus process. If you don't wait for the green target square your pictures will always be blurry and washed out. Can you attach a mini-tripod to these things?
