I recently returned from a trip to Hawaii where I was changing my lenses once/twice a day. None of the photos showed any signs of dust. Today, after couple of months, I took out my camera to test a new macro lens I bought and seems like there is something on the sensor. Here are some samples:
Initially I thought there might be a scratch on the lens but all my lenses show a "scratch" like thing in approximately same position. But it does not show up on all the images. I took some more pics and it does not show up:
What could it be? I can't see that in the view finder though. But I do see couple of tiny dots in my view finder which do not show up on any of the photos. Tried really hard to take a picture of my view finder with my cell phone. Here are the tiny dots visible in my view finder:
Do I need to get it professionally cleaned? Any suggestions?
Thanks
