Circle of confusion pixel size
WebThis again means that high pixel density sensors over 36MP can very quickly lead to lower image quality if you aren’t careful about your aperture—another reason that people are sometimes disappointed that their new high megapixel camera isn’t delivering the results they expect compared to their older camera when they zoom in to 100% ... WebJul 9, 2011 · Therefore, in theory, 1.4 times the pixel size (the length of the diagonal of the squared pixel) must be equal to the diameter of the Airy disk. This would imply that the pixel diagonal is the diameter of the sensor’s circle of confusion.

WebCircle of confusion – size matters Size is the critical factor. An ‘acceptably sharp’ CoC is defined as one that appears sharp to the eye on an 203 × 254 mm (8 x 10 inch) print viewed from 305 mm (12 inches) away. In practice this works out to about 0.25 mm (1/100th of an inch) on that print size.
