comment 10 months-old Ilford “Rapid Fixer” concentrate, is it still safe?
It's one of those rules of thumb, but I tracked this down in the Ilford Rapid Fixer documentation (www.ilfordphoto.com/Webfiles/2006130218312091.pdf). "In order to avoid the risk of insufficient fixing. film should remain in the fixer for twice the time it takes the emulsion to clear. Fixer should be discarded when the clearing time in used fixer exceeds twice the clearing time in fresh fixer."

comment Are all fixed-lens cameras mirrorless?
There were a number of 'pellicle mirror' SLR's which had a fixed mirror, including the EOS 1N RS and the Nikon F2 HS. These mirrors were partially reflecting, so some of the light went up to the viewfinder and the rest went to the film. Advantages were that when motor driven these cameras had very high frame rates, and no vibration from mirror slap. Disadvantage was that the light hitting the film was attenuated by 1/3- the portion that was redirected to the viewfinder. Search for Pellicle mirror on Wikipedia for a comprehensive discussion.

comment How do I get dust particles out from between the layers of my polarizer filter for my camera
Yep... I tried to make that clear. If he's gotten 'wet stuff' between the plates there may be contrast and/or flare issues (much more so than dust)... But 'wet stuff' may not be clean-upable.
