wow, I've seen condensation on a lens of mine in an extreme situation, but it certainly went away when the lens finally acclimated to outdoor conditions. And I'm talking about taking a lens out of an air-conditioned home (probably a cool 72 degrees) and outside to 90s heat and humidity of a N Carolina beach.

It fogged big time. Want to say it took the lens about 20 minutes to acclimate to the change in conditions but it did eventually clear up both inside and out.

Hope your lens clears up. Kinda scary to be honest.

What has happened to the OP is not normal, imo. Just a month ago I was in Cuba, took camera/lens from air-conditioned room to pool area (can it get more humid than that), got into pool with the camera and took shots of my wife standing under a, good sized, man made waterfall. I noticed my 85/1.8 (same lens as OP) had fogged up badly, front and rear element, as did the mirror. Took about 20 minutes for all to clear along with some help from a microfiber cloth (just the lens, not the camera mirror). No condensation inside the lens, at all. If that would have happened, I am sure there would be "water marks" left behind, permanently.

It was over 90F at the time.

I had my lenses stored inside a very AC'd house in the FL keys and would take my camera outside and it'd fog up for about 10 - 15 mins. 5 hours is not normal.

My thoughts, also. It may have taken a dunk at some point in its history.

I would try and get my money back. Having to go through this exercise every time isn't worth it.

Well this is depressing.

There was nothing I really could have done when I bought it from the guy.

It checked out fine, no marks inside the glass, I held it up to the sky and it was clear.

Its been 10 hours in the rice overnight, its getting better. Theres a little bit of dots on the edges and in the middle, some moisture left.

Its probably fongus, in that case this sucks and I just have bad luck!


Edit: I tried to take photos of the lens and it didnt come out well. Anytips?

The thing is I didn't do anything wrong.

How much would they charge anyways? Its probably really expensive without cps.

You didn't ...except purchase it. I suspect that the guy who sold it to you dunked it.

Hes a member on the forum,

When I inspected the lens I saw no signs of any damage. I tried the lens out, put the files on the laptop and still, nothing.

fwiw, I just had the focus motor replaced and lens calibrated on my 85mm for $180 at a local camera shop. I couldn't imagine a cleaning and calibration costing more.

Good luck.

Right now its face first in a bowl of race, with the rear side sticking out.

I will go to my local store and try to get those little gel packets.

Is it too late to recover?

Anything else I should be doing?

Its in my room right now, and the fan is on.

Keep it away from your other lenses. From the looks of everything and what some have also suggested, it seems like your lens was submerged in water before.

I would probably keep it in the sunlight as well? To hopefully prevent any fungus from growing. I've read before that UV rays help clear fungus. Don't quote me on that though...

I can't believe I was sold a lens like that.

Why did it fog up when I used and not when I bought it... Gr!
