Stuck filter on Nikkor micro 105mm f2.8D
Mar 4, 2012 03:44:45 #
I just picked up a used Nikkor micro 105mm f2.8D via Craigslist. It is near perfect except for a stuck filter ring. The filter was shattered and all that is left is the outer metal frame-ring. It does not seem to be bent in anyway and I can screw another filter over it. I can remove the metal "barrel" part of the lens that the filter ring is attached to so it can be manipulated without the vital components attached. I tried clamping the ring with channel locks and twisting by hand but it will not budge. I don't want to deform the thing and ruin the "barrel". Any ideas on how to get this sucker off? Thank you.

Sounds like it is slight corroded on the threads or slightly bent. I'd try a micro drop of a mineral spirits (or even WD40) on the filter threads. Leave it sit 15 minutes, and try again. Clean it all up with lens cleaner and be careful the stuff does not get into the lens!
I also DO NOT recommend using pliers (Channel Locks). Try using your grandmother's jar lid techniques - like tapping gentling all along the perimeter several times. Also, get one of those rubber jar remover pads that every church seems to give away to gain some manual leverage.
Failing that, I was successful applying ice on just the filter ring (carefully) while keeping the lens body "warm". The difference in expansion of the metals enabled me to remove it with a rubber jar lid pad.
Good luck and take it slow. No pliers please.

LOL I bid on that lens too!
Hit the camera shop and get a filter wrench in that 52mm size. But first, try to find a fairly wide rubber band that fits tight to the filter and twist, I have done this many times with success.

Oddly enough, sometimes TIGHTENING it will loosen up what ever is causing it to bind. Then, if this works at all, it seems to unscrew rather easily. You won't have to actually make it move in the tighten direction, the pressure often seems to be enough.
This has worked for me numerous times with anything threaded--but not always!

A filter wrench? Wow. I did not know they existed. Thanks. But darn -- its another gadget I may have to buy (and do I need one for for each size filter?)
Seriously, the only filter I have ever had problems with was a polarizing filter after a month on the ocean. It is hard to get a grip on the inner ring. Will a filter wrench work on a polarizer?

That was why I bid on it, you got a good buy! Sometimes simple is best, I always have a couple wide rubber bands in my camera case just because they come in handy in our ever changing weather conditions out here.

Strap Wrench .... cheaper than filter wrenches, made with a flexible rubber strap that grips as you twist. The small one is the perfect size for lens filters, cost is $6.00

Try runnin hot (very hot) water on the filter ring. Heat expands metal (or any thing else). Should come right off. Unless, of course, it cross threaded. That's a whole new 'ball game'.

Kerosene, submerge it in Kerosene for 24 hours. If you don't have Kerosene a 50/50 mixture of diesel fuel and lacquer thinner will do. Then tap the center of the lens, right in the center of the filter, 4 or 5 times will a ball peen hammer

I recently had the same problem due to moisture creeping into the threads of the filter/lens interface. Carefully add a drop of Breakfree (available at most gun shops) and give the filte a good swipe with a 5 lb. mini-sledge hammer.
Shazam ! Problem solved...
If this fails, I have alternate methods involving dry ice and a blow torch.
