3.6. DISABLING THE LENS MOUNT CHECK 21

1a) Minolta made some Leica-compatible RF screw mount lenses for various rangeﬁnders (both screw

and focus cams work on both brands)

1b) Minolta made some Leica-thread, incompatible RF screw mount lenses for various rangeﬁnders

2a) early SR/SRT mounts lacked the aperture tab found on all MD mounts and most (or all?) MC mounts:

bayonet ﬁts, but auto-metering doesn’t work.

2b) regular MD/MC mounts with auto tab

2c) one rare 35mm guide number lens (aperture set per focus distance for old bulb ﬂash)

2d) screw-adapter bellows types

3a) early Maxxum mounts (eg, 7000 & 9000) do AF with any version AF lens (early Sigma 400mm f5.6

doesn’t work with 9xi, etc, but works with 7000,9000)

3b) mid Maxxum lenses work with all AF bodies, but lack DOF coupling

3c) newer Maxxum has DOF features

4) Vectis series lenses for R-3000 (digital), etc

Note: some Maxxums (eg, 2xi, 3xi, Spxi) cannot defeat their shutter interlocks so they can use T-mount

lenses or telescopes, etc, but most can (see sec. 3.6).

I think there more RF versions and maybe a twin-lens type or two. Let’s ignore the microscope and

enlarger options that could be used on.
