I've seen this question discussed before, but none of what I've been able to find has mentioned the Elan 7E/EOS 30 specifically, and there seems to be some disagreement (or at least very different results on various EOS bodies). <p> I would like to shoot Kodak high-speed infrared and Konica infrared 750 on my Elan 7E QD. Will the IR diode only fog along the sprocket holes, or will it ruin the image area? Also, I'm told that a dimpled back plate will change the result on the Kodak HIE because of the missing anti-halation layer. My backplate is not dimpled, but it does have some features, such as small Phillips screws. Will these show up on the image as well? <p> Thanks in advance to anyone who knows the answers... I have to make a pretty good drive before I reach to a store that sells IR film, so shooting some just to check is not very practical.
