2. Attach a red filter over the lens, and set the exposure manually as indicated by the film instructions for infrared
photography.
· Focusing compensation is required only for black and white infrared films, not for color. Read the film instructions
carefully for proper use of the filter.
<<<< Additional information not in the manual:
I just wanted to point out that not all Mamiya M42 lenses are safe to use with the P adapter for the Auto-XTL. If you
attempt to use the SX type lenses with the Auto-XTL P adapter, the aperture sensing pin will dig into the P adapter
face since it is not perfectly flush with the outer surface edge of the SX lense. Furthermore, since the entire moving
surface of the aperture ring of the SX lense comes to rest against the P adapter face, it will lock down the aperture
control of the lense and make it impossible to turn, therefore preventing SX lens f-stop manipulation. Mamiya
M42 AUTO lenses seem to be safe choices as are M42 Yashica-Yashinon, M42 Meyer-Optik and M42 Zeiss MC
Sonnar (S) lenses. Any aperture ring that rotates at the extremity of a lens should be avoided. Of course the SX lens
works perfectly well with the "ZE" P adapter for Mamiya ZE series lenses which it was designed for. Lenses with
Auto and Manual switches like Zeiss MC Sonnar work well with the Auto-XTL P adapter in conjunction with its
Auto Aperture pin. Lenses that have no Auto Aperture and only manual control of aperture appear to work equally
well like Meyer-Optik Orestor M42.
