I will be shooting with my R8 and he will be using his Minolta Auto Focus SLR. That is (I think) the problem. Last time I shot IR film (25 years ago) I was using my Rollei SL-35 and the lenses had a small red mark on focus scale for IR film. I focused, shifted to the red mark and shot and had good photos. My Leica lenses do not have such a mark and I think I have read that they are corrected well enough that I do not need to shift focus for IR. Every other lens (NON-Autofocus) I have seen has had the IR mark on the focus scale. Now, my student's Minolta has no mark, no manual focus scale at all and is autofocus. Will he be able to get well focused photos if he shoots at a large aperture or should he stop down considerabley to achieve sufficent DOF to have his main subject in focus?
