Me, exemplifying LBA? Pshaw! Compared to some, I'm the most meagre of misers.
[/me fondles latest unusable arrival, yesterday's MATI TV-SYNCHRONEX 25/1.4]
I don't *suffer* from LBA; I enjoy every buck of it! (That Mati cost US$4 shipped.)
Now, if I get an NEX, *then* the LBA will likely kick in! All those possible lenses...
For those unaware of the optics: Cameras possess a property called REGISTER aka FLANGE FOCAL DISTANCE, the distance from the lens-mount to the frame (film or sensor). Longer register lenses can more-or-less-easily adapted to shorter register cameras. Shorter register lenses MAY work on longer register cameras, but will not be able to focus to infinity without either 1) major surgery, or 2) an optical adapter that degrades image quality (IQ). Some common registers, in millimeters:
46.5 -- Nikon
46.0 -- Olympus OM
45.5 -- Petri, Contax/Yashica
45.46 - Pentax PK, Praktica M42
44.7 -- Exakta
44.5 -- Minolta AF / Sony Alpha
44.0 -- Canon EOS/EF/EFS
43.7 -- Minolta MC/MD
42.0 -- Canon FD/FL/R
40.5 -- Konica AR/F
38.67 - 4/3 system
28.8 -- Leica L39/LTM
27.0 -- Pentax Auto-110
20.0 -- m4/3 system
18.0 -- Sony NEX / E-mount
17.526 -- CCTV C-mount
Lenses higher on this list can be fitted to cameras lower on the list with straight (non-optical) adapters. Some slightly-shorter-register lenses MIGHT be fitted to slightly-longer-register cameras with only minor surgery -- I have a trick for putting Exakta lenses on my Pentax PK cams. But generally, longer-register brands are donors and shorter-register brands are recipients aka
leeches. Canonites
leech our Pentax lenses. Sony NEX'ers
leech just about everything. And when some CCTV and cine lenses around 10mm f/1.0 cost just ONE BUCK, you can maybe understand why optics junkies head for the NEX.
One reason for increasing prices of vintage lenses is that more Kx-Kr users (and Canonites, m4/3'ers and NEX'ers) find that they are very usable. Get them while they last!
