Any of the old pellicle mirror cameras, but almost all were film cameras.

Its Canon EOS RT, but it reflects 2/3 (66.66%) of light to OVF & 1/3 (33.33%) to film that results in noise as well as slower shutter speed.

SLTs sensor get 70% of light that served to EVF, only 30% goes to A/F mechanism.

But Canon EOS RT OVF does not blackout

I didn't realize that the pellicle mirrors "ate" that much light!
