Does the 35mm fisheye have a rear holder for filters? I'm intending to use the lens for infrared, so this is pretty much an essential requirement.

Yes, The old Takumar and "new" Pentax versions have them built in. I believe these are the same lens, and the configuration and weight appears identical? The following are, I believe, sold with the camera when new: UV, Y2, O2, & R2 filters. If you intend to shoot true infrared, as opposed to Ilford/Konica high red film, you might have to screw around a good bit to get the filter you want, in the right size, and working correctly. Depending on what you want to do, it is possible to use the 45mm lens as a special effects lens; effects not all that difficult by utilizing low/high camera positions, and sharp angles for "distortion". The 45mm uses standard 82mm filters. Of course, if 180 degrees is what you want, then you need either the fisheye, or a fisheye adaptor on any p6x7 lens between 75mm and 300mm. Most all 35mm fisheye adaptors work on medium format thought often these companies making the lenses didn't make adaptor rings larger than 67mm, so many P6x7 would be ruled out.

Keith: Regarding rear filters for the P67 35 fisheye, in addition to the rotating filter turret mentioned above, the lens also has a gel clip behind the rear elements. This is a bit awkward to use at best, but you can custom cut gels not included in the turret. A few other wides (45, 55-100, etc.) have this feature. good luck mark smith
