Camera calculator - Calculating the sensor diagonal, sensor height & width,sensor ratio and pixel size

The calculation of the sensor diagonal is helpful for selecting the right lens. The image circle of the lens must be at least as large as the sensor diagonal, otherwise vignetting effects will occour. Since many optical errors occur especially in the peripheral areas of the lens, an oversized image circle diameter is always ideal.
