I don´t know if any of you have the same problem. The problem is only 
visible at F11 or more. Just select F16 and point to a white wall an 
focus...

yes, I discovered one spot last week, too. I ordered my camera about one 
month ago. It was handled carefully. Spot is visible at F5.6

padaryk fotke su priverta diagragma (dideliu F, tarkim F16).

(zoominant - keiciasi F'as, objektyvas - 24-75mm equiv. F1.7-2.8)

Gal fotke negausiai ka pades, bet labiau ismananciam - svarbi aplinkybe.
