It made sense when half frame film cameras were popular. Now that half frame is for some reason called APS-C it makes less sense.

If you don't like it, why not type "24x36mm" ?

And as for 4/3 --- 4/3 of what ?

After posting more than 32,000 times I would think you'd have learned that micro-4/3 stands for a 2x crop factor sensor with a 4x3 format, rather than 3x2, like APS-C and full-frame cameras have. Of course, full-frame refers to a frame of 35mm film, but the sensors are actually approximately 36mm.

My understanding as a former Oly E10 owner, then early adopter of 4/3 DSLRs is the 4/3 nomenclature stands for two separate things:

The 4:3 aspect ratio

The 4/3" sensor size.

4/3 cameras and m4/3 cameras use the same sensor size which is the 4/3" sensor (17x13mm) which is made as a 4:3 aspect ratio.

4/3 is a complete (so called) open standard in its own right. The "2x crop factor" bit was never part of the 4/3 standard, just a largely pejorative term made up by other people.

But it makes sense, because so many 4/3 and m4/3 users adapt "full-frame" lenses to be used on their 2x crop factor camera.
