Circle of confusion pixel size
WebActual sensor size. This is the actual size of the Alpha a6300 sensor: 23.5 x 15.6 mm. The sensor has a surface area of 366.6 mm². There are approx. 24,200,000 photosites (pixels) on this area. Pixel pitch, which is a measure of the distance between pixels, is 3.89 µm. Pixel pitch tells you the distance from the center of one pixel (photosite ... WebWith digital sensors, the size of the pixel determines the size at which the circle of confusion (CoC) becomes significant when viewing at 100% crops. Any blur circle smaller than the pixel pitch will be recorded as a single pixel. Only when the blur circle becomes larger than an individual pixel will it be recorded by two adjacent pixels.
