Originally posted by Alex645 Good point; no it wasn't digital but it was using the translucent pellicle technology. It was the beginning of what we call DSLT today, but the first digital camera is attributed to Steven Sasson over at Eastman Kodak in '75, with Bryce Bayer developing the modern day digital sensor a year later.
Sasson built the first CCD based digital camera, the CCD having been developed in 1973. 8 lbs and B&W only. It had a resolution of 10,000 pixel (0.01 megapixels). It wasn't until 1986 that they had developed a digital camera capable of printing a photo quality 5x7.
You can pretty much count on one hand the number of cameras produced with a Pellicle mirror before Sony resurrected the idea.
1963 Topcon RE Super
1965 Canon Pellix
1971-1998 Nikon F HS, Nikon F2H, Nikon F3 HS
1972 Canon F-1 High Speed (For Sapporo Olympics)
1984 Canon New F-1 High Speed (For Los Angeles Olympics)
1989 Canon EOS RT
1994 Canon EOS-1N
And Sony has abandoned the idea again it would seem. Nothing since the A99 four years ago.
