Last October I tried out the Canon Pellix, a Canon SLR from 1965 that utilized a pellicle mirror (you can read that article here). This year I decided to try out Canon's more recent pellicle mirror offering, the EOS RT from 1989. Like the Pellix from nearly 25 years earlier, the EOS RT (stands for "Real-Time") has a fixed, semi-translucent mirror that does not flip up during the moment of exposure like on a standard SLR. Instead, 2/3 of the light passes through the mirror to the film, while 1/3 of the light goes into the pentaprism viewfinder. This means that you never lose sight of your subject -- there is never any "blackout" like on just about every other SLR. This makes the RT a handy tool for sports or street photography, as you can see the decisive moment as you click the shutter.
