Why 6:6 aspect ratio instead of 1:1?

    OK, I realize this is a fairly dumb and unimportant question, but it's been bugging me and I'm sure someone here has an answer.

    I noticed recently that on Olympus cameras the square aspect ratio is referred to as "6:6", while Panasonic labels this "1:1". Obviously these are both the same thing, but 1:1 seems like a more intuitive description.

    I presume there's some (historical?) reason why Olympus uses the 6:6 terminology, but it's lost on me. Anyone know what the reason is?

    6cm x 6cm was a popular film size for medium format cameras

    you apparently got 12 shots out of a roll of 120 film

    scary that these same people are designing the cameras and lenses that we spend so much money on.

    Ah, but those same folks who remembered "6x6" also remembered the retro look that the OM-D EM-5 ended up with. :thumbup:

    But if they were Americans we'd see "2.3622x2.3622" instead of "6x6" :biggrin: And the OM-D EM-5 would look something like one of these:

    It's sooooo much easier for we Yanks to figure out inches than that silly metric nonsense... :wink:.
