All this discussion of black & white IR film with the M6 has got me. I'm going to try it out. But just one point- the lack of focus marks on Leica lenses does not indicate that the cameras are unsuitable for infrared, but only that Leica felt that the markings were misleading since they were accurate only at infinity, so they stopped using them. In Osterloh's Leica R guide (sorry I can't remember the exact title) he explains all this and gives the formula for calculating the exact refocusing required for different distances. After I read that formula that I realised I would be very content with a smallish aperture and using the dof to cover the difference... ;-} - -- jb
