Re: Lens Coding
For most lenses, the bayonet ring is mounted directly on the back of the lens. 5 or 6 screws (P000 to remove) and it's off and the ring is replaced.
It's a 5 minute job. I've never really understood why Leica make such a big deal of it. It's said the lens is put on a test rig - lens mount with lens sensor and (presumably) some PC interface to verify the recognition of it. It's also said the lens is cleaned, externally, and the dozen or so lenses I have sent for coding have come back in good order.
So why don't Leica allow do-it-youself lens coding, or at least coding outside Solms/Leica UK/Leica NJ? Lost of theories...
- No test rig
- Incorrect mount will be fitted
- Mashed screw-heads
- Original mounts in "free" circulation
- Lens checks not carried out.
Who knows? There's talk here about lens "shimming", meaning the adjustment of the lens to focal plane by fitting spacing disks under the lens mount. I've never seen any evidence of them,
It's a mystery.
