I feel like I'm going crazy over the past few days with this camera, unfocusing itself, but then I notice this, circular spots on photos in sky locations or any flat area that's all the same color.  Again, lenses and sensor are clean.  What's mystifying is that the number and location of the circles are different on different pictures, some pictures have none, some have a lot, some are more conspicuous.  They don't appear to be marks on the optics anywhere.  Just what the heck are these things?  It's like this camera is haunted.  I'm getting closer to chucking it in the harbor with each passing day.

They look like dust spots on the sensor, but I don’t know since you say that the spots change from photo to photo.

I feel like I'm going crazy…

 

 

Be cool, body! Go slow and keep the groove… :P

These spots are normal, we all get them — except the freaks like
me that will buy a 4th camera to "weld" it to a long lens for eternity.

The three bodies I use with more lens flexibility are getting sensor
bunnies and these should removed through sensor cleaning. There
are many methods but the one I use the Eyelead for large sensors.

That's because a different crop is applied to the pictures but
I'm sure the spots stay all at their places until cleaned.

Going to go with dust on the sensor, you will notice some changes as to how many by what F stop you use, it will most likely be the smaller F stop the more you may see.

Some dust bunnies move around when the air moves in the mirror chamber. Most of them stay put.

 

If you have that much dust on the sensor, you probably have some in the sub-mirror assembly too. This would explain your AF problems.

Maybe this all does make sense then.  Going to try the cleaning regime again.

 

Thanks.

Well, how about that.  I did a cursory sensor cleaning with air and that fixed the focusing problem.  The spots are still there but that seems like a job for someone with more knowledge than I so I will try my camera store.  

 

Thanks for the help!

Yes. that's an easy but costly way out!

We all went through this. We were scared to do the cleaning ourselves
because of the false panic warnings spread around.

I tried the wet methods and was not satisfied. Tried the gels and bingo!
