Canon EOS 1N-RS in good working order. This camera has a fixed pellicle mirror instead of a moving mirror, so it's quieter than a regular SLR, has no mirror vibration, and like a rangefinder camera, has less shutter lag, making it a great choice for images that need very precise timing, like bird photography, sports, wildlife, and anywhere that the decisive moment has to be a little more decisive. The pellicle mirror absorbs about 1/3 stop of light. Takes 8 AA batteries. Body cap included.
Question: Is the 1/3 f/stop loss factored into all the exposure modes, including flash exposures?
I'm asking this question because I owned the original Canon Pellix QL and I had some under-exposed photos because of exposure meter errors.
The 1N RS has TTL metering at the film plane, after light has passed through the pellicle mirror, so yes, it compensates, but one should always do one’s own tests and set ISO or exposure compensation to one’s own process.
