Hi,
I got my EOS 1N RS the other day and had time to play with it a bit today but didn't get to shoot a roll of film through it (yet). The manual says there's a 2/3 of a stop of light loss due to the mirror. Has anyone verified this? I just compared my N RS to two EOS 3 bodies while spot metering different surfaces using the same lens and have found that mine actually has more like a 1+1/3rd of a stop of light loss - 2/3rds of a stop more than advertised. And yes, I've triple checked f-stops and ISO settings as well as compensations and metering modes. I'm somewhat puzzled by this and am wondering whether the camera could be faulty (mirror looks clean) or whether this is normal for this body? I know that only shooting some film through it can give me definite answers but it would be great to hear about the experiences of other guys using the camera so I know whether I should send it in for checking just to be safe. Thanks!
