Smashed IR-UV Filter, Advice Requested

Okay, I've tried gently heating it and gently trying to turn it on one of those rubber pads used for opening jar lids and the like. No luck. I can now see that little bits of glass are falling from the filter to the lens, so... rather than trying pliers, I'm going to send it to Leica NJ and ask for help. Thank you for all your help. Others on the forum would have the skills and tools to do this, but I'm not confident in my abilities to do this without messing it up, so off it goes.

I definitely wouldn't file notches or anything else while the filter is on the lens. Assuming it's a Leica filter, you risk getting aluminium (aluminum if it's a US filter) filings into the lens which will wreck the focussing mount.

 

Whilst the notion that filings from two tiny notches the filter could get into the lens and damage it, is laughably improbable, it is most disappointing that Leica chose to have their in-bought filters done of aluminium, because that has the notorious reputation for binding on lenses. B+W and Heliopan filter mounts are made of brass, which rarely bind unless the threads are fouled.

 

Oh, if you want to try warming the lens with a hair drier, that might help but go easy, warm, not bake. You don't want the helicoid brease dripping out of the bottom of the lens.

 

ROFL! Surely you jest. Check the liquifaction temperature for helcoid grease...oh, sorry, you said brease. My bad

Oh, give it a rest - people are trying to be helpful, here, and your attempt at wit isn't really helping very much.

 

I would have thought that generating swarf millimetres from the front of several hundred units of currency-worth of lens is not a very good idea, even if that swarf doesn't get close to going inside the lens.

Here we go again......

 

Vinay, go get a life elsewhere. Or, cut a few bellies open if that will make you happier.

P.S. Now let's see what verbal diarhoea will come as response.......

I don't understand how the drawing of preposterous conclusions is helpful, but in the interest of harmony I shall make an attempt to titrate the level of my responses to fit the status-quo.

Here at "Dictionary Corner", two words come to mind: pompous and windbag.

 

Pompous - adj. affectedly grand, solemn or self important.

 

Windbag - n. a person who talks a lot but says little of any value.
