slclick said:I'm seeing a size discrepancy here between these posts and other Super35 sensor size comparisons online. What is the real difference in size between aps-c and S35? I know it's a format difference from 3:2 and 16:9 but they're really not that much different in size are they? Frodo's mm2 measurements suggest they are.
Here is a source for comparison of size is: http://www.danielhaggett.com/blog/136-lens-comparison-and-crop-factors.
Basically a super 35 sensor has about 24mm width and 14mm height more or less. From which a typical 16x9 portion (1.78:1, widescreen size video) is used to record images. But cinema aspect ratio can differ between 1.78:1 (16x9, AKA 3-perf Super 35) and 2.39:1 (anamorphic). Typical spherical cinema lenses should cover the 24-ish mm width of the sensor. EF lenses designed for full frame stills can cover 36 mm width and can definitely do this. Canon EF-S lenses are typically designed for APS-C width of at least 22.2mm which is a little bit narrower than super 35 width so theoretically some EF-S lenses may not be able to fully cover the super 35 sensor without conversion or cropping.
