What infrared filter for my 30D?

[JDubya]

I'd like to get an infrared filter but I'm not sure which. I'm looking at the Hoya RM-72 b/c it's fairly cheap. Is that a good one or should I look at a something else? Also I'm not sure which size to get. I have two 58mm lenses and two 72mm lenses. I use the 58s the most, especially b/c the one Sigma wont work on the 30D (originally got it for my EOS Elan). So I guess go with a 58? It's a lot cheaper too...

Also, is the 30D decent at taking infrared images?

the Hoya R72 is a good filter, i use it but have yet to with my 30D.

I may be wrong but I believe dslr cameras have an ir filter for the sensor making ir use not very effective....no-doubt someone will post and clear this one up

I had some really poor results with the Hoya R72 filter.
It's not the filter, it's the camera. It blocks out most IR light and I needed exposures in the 20-30 second range to even see anything.
If you want good IR pictures, try places like

Converting the camera would be nice but not practical, at all. This is my only DSLR so I still need to photograph visible light w/it. and I don't want to do maxmax's IR/Visible conversion. I'm keeping the camera's internals stock.

I don't have a serious need for infrared, I just want to have a little fun w/it.

Picturecrazy: What camera did you use the R72 on?

I used it on a 20D, 30D, A40, and Nikon D70.

The 20D and 30D absolutely stunk using this filter. Others may have had more success than me but a minimum 5 second exposure is still too long!

The A40 had marginal success with it. It just had problems focusing.

The D70 worked semi-reasonably. Cranking up the ISO got me some pretty good, usable shutter speeds. The only pain was I had to focus with the filter off, turn off AF, put the filter on, and then take the shot.

So currently I am looking for a beat and used 10D, 300D, or D60 to convert to full time IR.

I suppose 5-30 second shots is livable for landscape photographers. But I am not one. You may want to give it a shot anyhow.

I have a 20D and have tried some IR using the R72, Steps go like this. Mount camera rock solid tripod, compose and focus, turn off AF, screw on filter, set camera to manual mode ISO 400/f4/30 seconds and trip shutter with release cable. Results are acceptable but with such a long exposure anything moving will be blurred, clowds, winf blown branches or water surfaces.

Some excellent point and shoot cameras that yeald hand holdable shooting are the nikon 950, olympus C-2000 or C-2020. I believe thay all use the same 2.1 mp sony chip. Its hot filter doesnt block much IR light, I think maybe only 1 or 2 EV's.
