Pentax and HEI, help!

[Scribble]

Alright, After using HEI for a few years, I have gotten the hang of it. But before, I was using it in a Nikon FM. I recently got an Pentax MZ-S, but before running a roll of HEI in it, I was wondering if the data imprints at the bottom would fog the film up.

The MZ-S has a feature I have never had the chance to use before, in which it imprints the apertue, shutter value, and the like at the bottom of the film, in between the sprockets. But I was wondering if this very same feature might fog up the bottom of the HEI.

Does anyone know?

My other question is what will happen if I use my Super-Takumar 50mm F/1.4 with HEI. The lens is a rare-earth lens, and so I was wondering what effect that may or may not have on the film itself. I quite like the yellowing to lowwer my film contrast, esp with Neopan, and now with Pan-F, but I was wondering what effect it may have with Infrared photography.

Thanks!

I believe you can easily disable that date-stamp feature. Pull out your camera manual and check on that.

Of greater concern is whether or not the MZ-S's infrared film advance counter will cause some fog creep into the frame when you shoot HIE. More often than not, this is apparently not a great concern, but you may want to find an ME body to shoot your HIE with. (An ME shares your MZ-S lenses. Good old Pentax.) You may want to run a test roll to see if it's going to be an issue with this camera.

I can't imagine the lens you've mentioned being a problem with HIE, but again, only one way to find out.

Can't help with the camera, but the hard radiation will have no more effect on IR than on any other film.
