Well, it's not a Nikon lens, but it IS a Nikon mount, so I hope there isn't an issue posting here.
That said, I accidentally left this lens out in the garage for the better part of the winter, and that has led to issues. My kid brought it in and put it in the kitchen... as my wife was cooking... from -10f with 0% humidity to 70f with 80% humidity... I think you can guess what happened.
After allowing this thing to dry out as best as I could there were still large water spots on the inside of the rear element. Since the lens was pretty much shot anyways, I tried my hand at disassembling the lens and cleaning out the mess.
All went well at first... Got it apart, got it cleaned, got it reassmebled. All screws in their original location, all shims where they should be etc. The issue now is extremely soft images at larger apertures.
Anything below about f5.6 is borderline useless. At f8 it's nice and sharp... at f2.8 I may as well have smeared the lens with vasoline. It never used to be this soft wide open. Yes, I understand IQ suffers with big apertures, but not like this. Never like this.
Any thoughts as to whether or not this is fixable without sending it in and spending the replacement value of the lens on repair? I don't mind making this my kick around lens to take in dangerous situations, but it used to be a really nice sharp lens and if I can get that back
