I hope you don't mind a canon user posting here!
Reading the review on dpreview for the M8 it talks about the "issues" with IR that the M8 has. I shoot quite a lot of IR with my 5d and it is a constant struggle due to the heavy low pass filter over the sensor. I end up with the camera blocking most of the IR and my IR72 blocking most of the normal spectrum.... so exposures can be very long.
It occured to me that the M8 might be the ideal Digital IR camera due to it's lack of an effective low pass filter.
Have any of you Leica type people expermented with IR on an M8, and is my theory right?
(I'm almost hoping you sy "no" so I don't have to sell one of my children so I can buy one!)

Better put the advertisement together. The M8 will work well as an IR camera if you put a daylight blocking filter on but you will need to experiment with exposure and focussing... seems a waste though.
Somewhere on the net, there's step by step instructions to removing the IR filter cover glass from one of the lower cost Canon DSLRs - this is typically used for astro-photography and it seemed quite straight-forward a procedure. Certainly makes more sense to buy a secondhand Canon body and doctor it, than buy an M8 and lenses; after all, you can buy a 5D with change to spare for the price of many Leica M lenses.
Here's a link to the article, it was a 350D.

From what I've read, the M8 actually isn't all that good as an IR camera - I know it sounds as though it should be, but alledgedly not. Can't remember the reasons given, though.
I actually bought a 350D with the intention of having it converted to IR use - there are guys in Australia and the States who will remove the existing hot mirror filter, replace with either clear glass or an IR filter, and adjust AF as necessary. Problem is I've rather enjoyed using the camera as a back-up/long lens camera, and haven't got round to it yet. But you can certainly get an s/h 350D and have it converted for about the price the 350D was new - sure, it's no M8, but it's a practical and reasonably affordable option.

I wasn't thinking that good IR performance would be the sole reason for buying an M8. Just that along with all the other benefits of the system this might be another to add.
