For those interested in more recent history, the history of digital photography.
And its phenomenal growth from 1991 to the present day.
I have here the Agfa Actioncam (1995) The first and only DSLR or Agfa got involved

30 years ago, a partnership between Minolta and Agfa gave us a strange camera.
Or rather two, the Minolta RD-175 and the Agfa Actioncam
The camera that served as a basis was the Dynax 500si
Big sensors used to cost a fortune to produce
Look at the astronomical price of Kodak DCS cameras!
Instead, they used three small CCD sensors of 380,000 pixels each (768x394) with a prism that generates three light beams.
Which gives after interpolation a final resolution of 1.75 million pixels (1528x1146)
Agfa Action Camera (1995)
Minolta RD-175 (1995)
1.75 MP sensor (1528 x 1146)
with a multiplication factor of 2
Price: $9,500 US
With a single sensitivity of ISO 800
Here I have grouped together the comparisons made with these two twin brothers.
