Re: Nope, originally sensor size

Please don't come to the m43 forum spouting "knowledge" about 4/3 that you do not have.

Four Thirds and m43 is named for the aspect ratio. You are very wrong.

I reported on the 4/3rds system for CNET and some tech magazines when it was introduced, including attending the official press unveiling in New York City in 2003. I was told directly and personally the origin of the name by both Olympus and Kodak engineering and marketing personnel (Kodak was a co-lead developer of the 4/3 system, which many people now forget). The name originally referred to the sensor size. (All the original 4/3 system sensors were Kodak devices.)

Thanks for the nice history report. Leave it to the PR types to further confuse a confused situation (using the old vidicon standard for measuring sensor size). Beyond that, the tech. spec. for 4/3 and m4/3 says "The Micro Four Thirds System is designed to be compatible with the aspect ratios specified for the Four Thirds System, including 4:3, 3:2 and 16:9." (from the four-third organization website) So, not only is 4:3 not distinctive of sensor size of m4/3 in comparison to almost anything else, it does not really say much about what aspect ratios are supposed to be supported by the standard.

But, anyway, the OP just wanted to know about sensor sizes, and what 4/3" has to do with the sensor size of m4/3 cams, as I read his post.

Thanks for chiming in.
