So, there is no need to mount an IR filter in front of the lens - meaning you can actually see the shot through the lens while composing. (Correct me if I am wrong.)
A question though - as you're looking through the lens, it will be out of focus, correct? I assume the debug alterations are for adjusting autofocus lenses.
Hey Sean, you really know things! That's right, you can shoot w/ the camera as you are using a normal camera, don't need an IR filter in front of the lens. But the exposure would be different. Probably need to add about 2 stops EV to get correct exposure. But still alot easier to use than using an IR filter in front of a lens which most time you need to use a tripod and long time exposure.
And yes, he added about 400nm to get correct AF, the target from the view finder seems out of focus, but the actual results are spot on, a side effect I guess. Not really a big deal 'cause you'd be shooting landscapes mostly when taking IR photos.
My friend is very comfortable modifying both Ds and K100D. If some here is interested, he can do the service too (you send in the camera, he does the modification and sends it back to you) for a fee which is less than half of what maxmax charges for
. The best thing is, he can put the IR cut filter back and restore your camera to a normal one if you don't like the IR results. You just need to pay the shipping fee for restoration.
I might get my own K100D converted when the K20D comes out (then the K10D will become a backup).
