Hello Everyone,

I recently bought a used Oly 60 mm from B & H. After taking some random test shots, I noticed few red dots in bunch of the pictures. I am attaching one example (bottom inside the black circle). Does anyone have any idea what this might be? Or is the lens defective?

Many Thanks for your comments/feedback.

I am assuming this is a jpeg image. Did you shoot any raw images to see if they were present? And, did you try to remap the pixels on your camera? They look like hot pixels, and these are usually mapped out in raw images. Unfortunatley, they do appear in jpegs. I could be wrong, but it is easy to check, and remapping does not hurt anything. Then again, it could be a bit of flare. Do you have any other samples?

Yes, these are stuck pixels and you can just map them out without any concern.

These can easily be fixed on post process if there's an image that you want to otherwise keep.

On a side note, I had a similar issue with Oly 17/1.8. I got this blue comet like flare in some of my pics during a balloon ride. Now it could be just flare but I also noticed a tiny pinhole size mark on the front of the lens (new) so wasn't sure if it had anything to do with it. Thanks again.
