Now, I'll stick with a metal shutter. On the other hand, resolution is so low with IR, that any lens will do. s.d.

That's interesting. I've never gotten hot spots on IR with my M3 or IIIf. I did get dark spots from the dimples on an Olympus OM pressure plate, though, before I switched to only RF cameras for infrared. I bought a bunch of HIE last November. At my usual rate of shooting it I should be set for about twenty years.
