Data Register Lensa Manual Fokus

Post  didonhp on Sun Feb 06, 2011 1:53 pm


Dapet data bagus buat yg suka ngoprek mounting...

supaya lensa bisa dapet fokus di infinity, jarak register (flange back distance) lensa harus sama dgn register kamera nya, jadi logika gampangnya lensa yg punya register panjang paling memungkinkan buat di modif/pakai adaptor utk bisa masuk ke dslr yg registernya lebih pendek.... spy fokus nya jatuh tidak didepan sensor.

ini ada data register beberapa system yg sering di oprek...
(di c/c dari forum tetangga... thanks to mr yadisl dari LM)


Spoiler for data register:

Minolta AF bayonet 44.50
Minolta MD bayonet 43.50

Nikon bayonet 46.50

Olympus OM bayonet 46.00
Olympus Pen F bayonet 28.95
Olympus E1 bayonet 38.67 (38.80?) (adapter for OM lenses seems to require focusing beyond infinity, perhaps 0.13mm error due to film-thickness??)
(aka 4/3 or four/thirds)

Canon EOS bayonet 44.00
Canon EX1/2 VL bayonet 20.00
Canon R/FL/FD breech or bayonet 42.00

Pentax K-mount bayonet (dan juga M42) 45.46


dari data diatas bisa diliat kenapa system micro 4/3 dgn register 28.95 bisa dipasangi semua lensa manual krn memang registernya paling kecil... dan juga kenapa lensa canon FD (42.00) sukar di modif utk ke mount lain yg registernya lebih panjang (jadi harus pakai koreksi optik yg bisa menurunkan kwalitas lensanya).

kalau mau lebih lengkap datanya bisa diintip disini
