| p.1 #1 · need an NEX favor: adapter measurements? |
I'm trying to fashion an adapter for a scavenged lens, and I'm trying to figure out what my options are for shallow mounts. If any of you with adapters could do a couple of quick measurements, you could save me a lot of hassle.
The shallowest adapter I've got is for an Olympus Pen-F, and it's about 16mm total depth, including the flange of the mount. If I remove the chrome locking ring, it's about 14mm, but that's still too deep for me to reach infinity focus. Something around 10mm would be better.
I need at least a 27mm hole to accommodate the rear lens assembly, and it could be up to about 47mm.
A c-mount adapter is definitely shallow enough, though I'd have to enlarge the hole, and I think it would be less stable than I'd like.
Would anyone here be willing to measure your Leica screw mount and/or M mount adapters? I mostly need the total mount depth.
If any of you happen to have a screw mount adapter like the one linked below, it would also be a huge help if you could tell me the width of the chrome threaded insert -- I may be able to remove the insert, and fit my lens down inside the adapter.
