water mark? fungus? inside front element

[merehzezi]

I went to shoot today only to notice this spot on my lens... I tried to clean it but it seems like it is on the inside...

Is this a dried water spot? fungus? Is there a way I can fix this? Should I just send it out for professional cleaning? (If it can still be cleaned 🙁 )

Nasty looking. It sure looks like coating damage. Are you sure it isn't on the surface? Glare some light on it and look for a surface disturbance.

It may well not have any noticeable effect on images though. It is surprising what causes problems and what doesn't.

I agree, it looks like coating damage.

I doubt it's on the inside if it suddenly appeared. I had beer splatter on my gear and ate the coating at the lens in a couple spots. Didn't affect images, but didn't look like this. I've seen and cleaned a lot of nasty lenses, but nothing like this. I'd get a tech to look at it.

I haven't shot in a while so I don't know how long its been there. It wouldn't come off when I tried wiping the front.

I finished a roll today, and will see if it comes out on the photos. But I will probably still take it to a tech sometime this week.

Thanks everyone, Merry Christmas!
