I had it done by a local repair guy. The conversion does not require a
filter in front of the lens. The conversion was done a few years ago,
on a camera that I did not use any more. Total cost of the conversion
was about $70. I did it just to experiment with. You can twist my
fingernails, and I can't give you more information.

Why not call your local guy and ask him what he actually did to make
the conversion?

because he'd rather argue.

removing the infrared cut filter turns it into a full spectrum camera,

pass filter on the lens to cut visible light if you want infrared.



Correct.



The old Olympus C2020 never had an IR filter and works well for IR

photography if an R72 is used with it.



Here is a page I made using this technique:



http://www.netaxs.com/~mhmyers/ir/gsir/gsir.html

They show the efects well, although I couldn't get teh movie to do anything other than show a blank white background.




I see the problem. I'm working on it...

Still doesn't work in firefox V31 I think
but OK in IE V 11

Strange. It doesn't work on Firefox for Mac either but it does work on
Chrome and Safari.
