I find that with my istD with the 21mm DA and a Seperate viewfinder of the same or similar focal lengthattached to the hot shoe U can hand hold at iso 400/ 800 on a bright day and get very good results.

My previous post mentions a used istD being a good IR camera. If you read my new post on thread "Infrared With The *ist D" I tested an istD, K100D, and modified K110D. To my surprise the istD and K100D came out roughly equal with a Hoya R72 filter. This contradicts what I and other have been saying.

I have found my *ist D to be similar in IR sensitivity to the *ist DS, which is to mean pretty good.

Comparing them to a K110 that has the IR cut filter removed doesn't say much - every digital SLR is a great IR dSLR with the cut filter removed. The *ist D/DS and K100/110 are good for IR because the IR cut filter is weak, and you can use it unmodified with decent results handheld. The K10D has a much stronger IR cut filter (I'm assuming) and can't be used handheld at any ISO.

I have been using my K100D for hand-held IR.

Hold the camera in your right hand, the R72 filter in your left hand, compose and focus, place the filter in front while keeping steady and click.

You get 1/20 to 1/125 at ISO1600 in daylight, I shot some at 200mm, ISO 3200, hand-held!

Focus should be adjusted for IR though, doesn't it?

If you are using an auto-focus lens, it will correctly focus for you. (The AF mechanism 'sees' IR light.) If you are using a manual focus lens you will have to adjust the focus spot based on the mark on the lens. Unless you have a lens without an IR mark, in which case you'll have to shoot-check-adjust-re-shoot.
