I wondered when to turn it on or off.
Now I found a real good reason.
One lens I have is the very long doublet, leica R 400/6.8
I was getting some really strange darkening on one side of the frame-- it was driving me crazy.
note dark top.
this was the only lens I saw this occur--I thought it was some stange issue, though the thing is bulletproof.
Today I was testing, saw this again, and turned the first curtain off.
Gone.
Totally gone. pefect even exposure. I was flabergasted.
These are single shots---so I don't know what it is, but it hates the first curtain.
as of this writing I think only the 5n and 7 have a first curtain (not sure about the video cameras).
at some point I'll do a before and after _________________ Making MFlenses safe for the letter *L* |
