Hello!
Out of foolishness or ingenuity I bought a brand new Fujinon CCTV lens with an impressive f0.85 and 25mm, and c mount.
Is it usable on any of the new m4/3 cameras out there? With how much modification? Specs are here:
http://www.rmassa.com/specsheets/CF25L.pdf
I am facing many hurdles, the most serious of wich is the back of the lens protruding 2 mm into the shutter of my g1.
Here are the numbers:
20.0mm m4/3 flange to sensor distance
-17.526mm c mount lens to sensor distance
= 2.5mm all c lens will have to be mounted with rear inside camera
+9.6mm rear element of this fujinon lens
=12.1mm space needed after flange (inside) camera
-9.7mm flange to shutter baffle in g1
=2.4mm space deficit
-0.5mm can be shaved off from the back of the lens
=1.9mm still needed
Could someone please measure the flange to shutter baffle distance
in the other m4/3 cameras like pen and gf1? Thank you
(How much focus to infinity do I loose with those 1.9mm?)
