Canon's Terrifying Recommended Way to Remove a Stuck Filter

Canon's Terrifying Recommended Way to Remove a Stuck Filter

Ever have a filter get stuck on the front of your lens? I personally have not, but I can imagine how irritating it can be. Travel photographer (and friend of mine) Craig Pulsifer posted the method he was instructed to use by Canon Professional Services to his blog. His warning: this is not for the faint of heart.




1. Use hacksaw to cut rim of the filter down to the glass.




2. Use Ballpein hammer to strike filter glass in progressively hard taps until filter glass breaks.




3. Pick out shattered glass of filter.




4. Blow off glass/metal bits, then using pliers, bend/peel edges of filter rim into the centre of the filter to pull pressure off of inner threads of lens.




5. Using pliers, bend/peel edges of filter rim into the centre of the filter to pull pressure off of inner threads of lens.




6. Again, blow off glass/metal bits, and replace with new filter.




7. Praise God that it worked!

I've done this before on a couple of lenses (that were not my own). It's fairly easy. Just don't scratch the glass.

Also, before the filter/no filter flame war heats up, use what you want to, it's your own gear.

 "filter/no filter flame war" -> It could have been a polarizer or anything. ;)

Or you could get a pair of filter wrenches for about $10 and keep them in your bag...

There is a much easier way than this...Cut with hack sack on both sides and just you use the hacksaw to rotate the filter by inserting the hacksaw blade in the groves which you cut...It works...I tried it before

 That's what I was thinking he was going to do when I saw the first step...

Same here

 Yup, that's a fine alternative.  Trouble is, the Canon tech warned that I might strip the inner threads of the lens body if I tried to manhandle the filter off; hence, the extra precaution.

Or wrap gaffer tape around the filter and remove by hand.

Rubber band works too!

Twice I've encountered filters which couldn't be removed.  I tried filter wrenches, but they couldn't grip it strong enough.  Eventually, I went to an auto parts store and bought a pair of 4-inch hose clamps.  Clamped one to the filter and one to the lens barrel.  Filter came right off.

Nice approach! And it saves the filter.

thats a pretty good idea

Ha ha! Filter wrenches... get it?? Just wrong kind of filters, but it worked!

did canon recommend to have steril strips and bandaids close by? also, most camera makeers dont recommend blowing on the  lens in any way, since the acids in your breath can harm the lens.  this vid has to be a joke, a painful one.

You'll notice that Craig has a blow tool. He never says blow with your mouth.
