Does the MX cope with IR film?
With respect to horizontal shutter and cloth, for me it is a simple matter of opening the back and looking.
flash sync is 1/60
info on IR films is due to the cloth shutter not being opague for IR, remember IR is heat. it was a published fact in the 1980's
There used to be a series of books called "the pentax way", "the nikon way" etc,,, that described the camera lines in the 1980's. full specifications were in there,
If I dig deep in my archives, I might be able to find the manual for the KX. I think I had one.
That gives me an idea for the website. A manuals section for old lenses and equipment.
