My Nikkor 105mm Micro was giving me a hard time, so after a bit of examination I discovered that the aparture blades were stuck on wide open. I guess I got burned on the purchase. It was also my first MF lens, so I kept it. Sadly, I didn't own a drybox at that point, so suffice to say it accumulated fungus. Poor lens. I was about to throw it in the bin, but then I decided to put a Tamron doubler and go for a shoot for memory's sake.

Here are the results:

Very Happy
This is a well regarded lens! Try to clean and fix it!
The result with TC 2x are surprisingly good. With some post-process to bring more contrast I would say VERY GOOD!

I am sure someone would clean and fix a lens like this - old Nikkors are still very useable so keep their value

unless the fungus has permanently etched and damaged the glass, I would get it cleaned.

How would you know short of taking it to repair shop and getting it cleaned?

I guess you wouldn't except if they just get started and the first glass they try to clean is ruined and they don't have to bother doing the rest or putting the lens back together the price would be less than if they did the whole job as planned.

Lenses do accumulate fungus, yes.
But it takes fungus a long time to etch the surface of the glass. Even if the coatings might be affected it is worth getting a quality lens cleaned.
I have just had a couple of lenses de-fungused. The whole lens needs to be treated to not only remove the fungus that is there, but also the spores that aren't visible so that when the lens is re-assembled, the fungus doesn't start growing all over again.
The most costly to treat was billed at $68 and this included a full clean, re-lube and de-fungus and re-alignment.
Worth every penny on a valued lens.
If you are still going to throw the lens away, I will gladly take it off your hands.
OH

Anyone recommend good repair shops in the USA, I have a couple older Nikkor lenses that I would LOVE to have cleaned. Can they go directly to Nikon USA?

Ive not used them for repairs myself, but you might call the number given for repairs at KEH.COM
Ive bought many pieces from them in the past and so have many other mflensers from this site.
They are big on Nikkor, as you can see, if you check out their site

Most early Nikkors are quite easy to open.
Cleaning fungus is easy. I use just Isopropyl alcohol.

My experience with Isopropyl alcohol is that it is quite weak battling the fungus. On the other side it is very friendly towards coating leaving it intact.

I got it cleaned at a bazaar type stall. He didn't fix the blades. Just cleaned the fungus. He used a white substance cream like and even his shirt at times. It cost me like and 50 bucks.

don't know about the white cream, but Ive heard using a shirt to clean lenses is not a good idea, (scratches).

I use distilled white vinegar to clean and kill the fungus, and distilled water to remove residual vinegar.

where do you live?

For cleaning fungus I use a bathroom fungus cleaner, doesn't harm coatings and kills fungus (clears the glass) in minutes. some coatings (like the canon FD's) get 'eaten' away by the now removed fungus so it might leave a permanent mark but in most cases you get clear glass and it stays clear (it won't return after 24 months Smile ). I also clean the parts that where in contact with the contaminated glass (housing parts etc). For final cleaning I give the glass a bath (Q-tip/cottonswap) with dishwasher (droplet in 250mm water, removes heavy grease) and finally clean the glass with ethanol(99+% pure).
(that sh*t is dangerous, don't think lightly about using such a flammable liquid. If you spill a litre bottle you have a real explosion hazard, because of it's quick evaporation. for safety put some ethanol in a smaller container 50/100ml and use a good ventilated room to use, unless you want brain damage Laughing )

I took three of my lenses including this one to a pro repairman and he did something like the above to clean and fix them.all came out excellent and cost me around $90. It would have been much more to get them replaced. No giving away sorry Wink I immediately put them to use for a shoot with a model. I have to admit I love watching the process of repair and would love to learn the process but the more I watch them at work the more daunted I feel by the experience needed plus I wonder if there is any money in this business. My gf was of course impressed he made 90 in a day when u consider the local wages are so low 10 a day for minimum wages.

Mind you being a foreigner I was offered everything from 55 1.2 to a Rolleiflex
