Some Camera Format Numbers

I created the following little spreadsheet last night. I think it provides an interesting way to think about comparisons among various camera formats. It uses the familiar concept of “crop factor,” but it moves the baseline to two other format besides just full frame.

I won’t say more at this point, but you might be able to draw some inferences about various format options if you spend some time considering these numbers. (If the chart is hard to read, click it to open full size.)

Film and digital camera formats using crop factors normalize to full frame, mini MF, and 645 medium format film.
