Ok, looks like im starting to have a problem with my PDR3300. As you can see on this picture, there is the big blotch in the sky. It only appears in such shots?
I have recently upgraded the firmware to 1.06A from the 1.05A that came with the camera. I dont recall seeing this with the old firmware. Any ideas?.

From here it looks like it could be dust on the image sensor. Do a couple of GOOGLEs for 'image sensor' and 'dust' and etc. Should get plenty of info.

If the blob is caused by dust, you will hafta be the one to clean the unit. Sending the camera to a shop isn't gonna be very cost effective! :O
