1.3x, 1.5x, 1.6x, where did it start?

I was thinking about the EF-S lens thread here and I wondered about all the different times factors. Then I got to thinking...did the camera world not go through this back when the 35mm came out? I am sure going from 4x5 or 2 1/4 square to 35mm made many people balk. Remember 35mm was considered miniature at the time, today only Minox is miniature.

Don't forget 1/2 frame 35mm.

Word has it that the 35mm format came from exposing a 24mm movie film sideways and 2 frames at a time.

I got this from this article on [url]www.kenrockwell.com:[/url]

[font=Georgia, Times New Roman, Times, serif]Digital SLRs take advantage of using sensors about 16 x 24 mm, close to the original standard 35mm (movie) film standard of 18 x 24mm introduced over 100 years ago and still in daily use in Hollywood movies and TV. [/font]

[font=Georgia, Times New Roman, Times, serif]When minature still cameras were designed to use 35mm movie film in the 1920s they were called "double frame" and shot a double wide frame of 36 x 24 mm. This remains the size of today's 35mm film (still) cameras which are fast becoming obsolete.
