Stuck UV Filter
Feb 12, 2014 22:57:09 #
Been trying for ages to get the UV filter off my 100-400 Canon lens.Finally laid lens down on carpet,got a screwdriver with a narrow blade,placed between lens and said filter,twisted slightly and hey presto off it popped.much to my relief....
Did read else where a Canon techician recommended using a ball pein hammer,smash the filter glass and then unscrew outer filter ring off.Seemed a bit rough to me.
Hope it is of some use to someone out there.

Dang Daryl!! Like you I think the hammer is a little extreme. I think on my UV I have enough room to grip the back section with a filter wrench but haven't tried it though. TNmike

Most grocery stores one can find a small square rubber pad with bumps on it designed for help in opening glass jars with metal or plastic lids for a buck (1-3 per pack), harbor freight tools also sells a small strap wrench made of plastic with a adjustable strap thats multi-purpose although the rubber lid remover is far more compact and easily fits in camera bag.

Or you can do like I did-
Fall off your road bike with lens unprotected in backpack, have lens make a direct hit on the pavement, break UV filter and jam ring into lens. Take to local shop, have filter ring snipped off only to find lens ring receptacle damaged. Send to Nikon and have lens repaired for $400.
Probably a bit more extreme than the ball peen hammer!!

Yes a filter wrench would have handled it.

Press the filter against the lens while unscrewing. It helps and is cheaper than buy a hammer.

Filter wrenches are nice to have around in such cases. I have used a heavy-duty rubber band around the filter, and that helps. Keep in mind that it is [usually] a matter of friction and not of strength. If you grip the filter too hard, the relatively thin metal springs slightly and is stuck even more firmly.

After asking everyone in my family to try, I used a thick rubber band around the filter. That did the trick. Remember righty-tighty and lefty-loosey. Turning it in the correct direction is a priority :)

Are you sure that wasn't a Nikon technician explaining how to get a filter off a Canon lens with a hammer?? :) :)

Rather than use a ball peen hammer, you could use a hacksaw blade to cut into the filter ring.

They make wrenches today that have a gripping strap as the clasp or cinch. It will grab pipes and UV lenses and put on a force that will delicately muscle anything off. I have two in my box, one to old steady and one to twist. No need for destruction, and it never leaves a mark.

How 'bout dipping the filter and just the front of the lens in warm water? It works for stuck lids on jars. Don't know about the seal on the lens, though.

A small spanner wrench may work, too.
Note that the dissimilar metals of the lens threads and the filter threads may expand or contract differently, causing a binding of the lens filter which tends to lock it in place.
Hence, if you attach the lens filter in, say, a warm condition, and then later try to unscrew the lens filter in a significantly colder condition, the dissimilar metals will likely have slightly changed size enough to cause binding of the lens filter.
I also take the precaution of only snugging a lens filter to the lens threads, never cinching it. The lens filter then usually backs off with a minimum of fiddling.
Hope this helps.
