No chopping, but that's for a short-register m4/3 camera. An LTM lens can be mounted, WITH INFINITY FOCUS, on these bodies: Pentax A110 (27mm), Samsung NX (25.5mm), m4/3 (20mm), and Sony NX (18mm). It could probably be finessed to fit on an old Olympus Pen-F half-frame body (28.95mm). For anything else without surgery, it's closeups only. YACL: yet another closeup lens. Bother.
In case anyone is interested, here is my
taxonomy of 39mm-thread lenses:
*
LTM: Leica 39mm thread and 28.8mm register. Zillions of rangefinder lenses are LTM. As I mentioned, these can be adapted to shorter-register mounts, but on Pentax SLRs they're only usable for closeups/macros - no infinity focus. Bother.
*
M39: Leica 39mm thread with Pentax 45.46mm register. Several FSU (former SovUnion) lenses are M39. Mine include Industar-50, Jupiter-9, Jupiter-11. Slip on a cheap M39-M42 or almost-as-cheap M39-PK adapter, and you're ready to go.
*
L39: Leica 39mm thread but no focusing mechanism, thus no register. These are mostly enlarger (EL) or bellows-macro lenses. But many older USA-made EL's have other threads: 29-30-34-38mm or non-metric. Confusion and hilarity ensue.
I am sorely tempted to get a NEX, if only to be able to mount LTM's and maybe some cheap C-mount glass (register= 17.526mm). And lenses from Konica, Minolta, Miranda, Canon, Fujica, etc. Or maybe that would be an admission that I'm a total slave to LBA and am doomed forever. What, 200 lenses ain't enough? Let's try for 300, 500, 1500 lenses! And more! You can never have too many lenses! HaHaHaHaHa... [/me gets strapped into straightjacket by LBA police]
