2/3 Sensor Mult factor
Hi guys
Just a quick question someone may be able to clear up. With a 1/3 sensor the mult factor is 7.2 when using 35mm film lenses. So what is the mult factor when considering 2/3 chips? There mult be a formula I guess but I haven't been able to find anything? |
Mat,
what a great question. sense it is twice as big would it cut it down to 3.6? Or does it reduce 7.2 by a third which makes it 4.824? Probably something totally different. Waiting to hear on this one too!! |
Mat
I believe you divide the 35mm diagonal measurement by the diagonal measurement of the ccd being used to get the crop factor. eg 43.3(35mm)/11(2/3)= 3.9 eg 43.3(35)/6(1/3)= 7.2 Gordon Hoffman |
Cheers Gordon, thats interesting. Am I being a bit dull if I ask where the ccd numbers have come from?

Mat not at all. This dicussion has a link to a site that seems to agree with what they came up with.
