anyone converted their istD to take infrared? I know it can be done/has been done/Pentax know it has been done but don't do it. Anyone know any firm that will do it?

The *ist-D will take IR images already - AFAIK it's quite sensitive in the IR region. You just need an appropriate filter.

Think the K10D is a bit more aggressive on its IR filter.

Hi Denise and welcome to the board!

There have been a couple of threads about this that I know of:

and earlier:

Several of us have had a dabble with it, with some good results - the sensor is certainly sensitive to IR, so you just need a filter and you're away!

Probably best to shoot RAW, then process to a 16bit TIFF to allow a fair amount of manipulation, as the tones always seem to be quite compressed when I've done it.

Hope that helps,

It is possible to have a camera converted to take IR. The IR filter is removed and substituted with plain glass (hopefully coated to prevent reflections). Then the only thing to remember is to correct the lens focus point. Older lenses with IR focusing marks are very useful in this respect.

This is done quite a bit in the USA, but I suspect less so here in the UK. It will cause a degredation of normal performance. The filter is there for a reason.

Any repair house ought to be able to do this.
Best regards, John

or you could just use Corel Paint Shop Pro Photo XI, and just the build in converstion and thus take the pictures in RAW and converted in TIFF and then opened then follow the instructions.

it gives the look, but doesn't damage your DSLR etc.
