I was wondering if anybody had any experience with the 5D2 taking infrared? I know Canon isn't the best brand for IR work, but I would like to get into it some. I've toyed with converting an older body like my dad's 450D, but I could start just with my current body and understanding the exposures are going to be long.
Anybody use their 5D2 for IR yet?

Is the 5D2 much different from the 5D because my understanding was that because of the filters on the cmos chip, the 5D cannot be used for IR?
ETA: not without modifying it: Tutorial

I have a 450D that works great for IR work. I just had it onverted a few weeks ago and as long as you set the WB right (greens) ur golden. The MKII is listed on this site...so its probably doable. Man 21MP IR...good stuff...lol

Well, my understanding is all dSLRs have an IR filter over the sensor, but some are better than others. The more it filters the longer your exposure. So you certainly couldn't use an unmodified 5D2 to take pictures with fractional shutter speeds, you may be able to do it with 2-30 second exposures. I was curious if anybody had tried.

Have you done the "remote test"?
Take a tv remote and take a pic of the transmitter while holding down one of the buttons. If you can see the transmitter led lighting up in the pic it will work with an R72 filter over the lens.
ETA: that doesn't mean the exposure times will be practical without a tripod. My experience with my 10D was that in bright sunlight, exposures of 30-60 sec were common at ISO 200 and f4. The stronger the hot mirror filter, the longer your exposures will be. Add to that the impossibility of focusing with the IR filter on the lens and things tend to take time. I had my 10D converted by LifePixel and I'm very happy with it. Everything about working with the camera is normal, it's just sensitive to wavelengths over the 720nm cutoff.

| Tried it w/my 40D...not so much, but I'm going to try w/my XT as it is supposed to work well. Ditto the cmos filter issue. W/my 40D, the camera can actually still autofocus through the filter!!! Might need to find an older model and convert. |

Canon DSLR's AF sensors are typically IR sensitive, so the IR filter is clear to them. |
