Calibration Score |
The calibration information shows how well calibrated this lens is likely to be new, out of the box. A higher score (close to 100) indicates that you are less likely to need to calibrate the lens. The score takes into account the likely amount of calibration required, the variation in calibration across many lenses as well as the likely improvement between an uncalibrated and calibrated lens. For zoom lenses, we also use parfocality, which is a measure of the difference in calibration required between each end of the zoom range.

Dust Impact
The following image shows the impact of dust on the sensor across all cameras. The impact is calculated from a combination of the size and opacity of the dust spot and the number of apertures that it affects.
Hot Pixels
The following image shows the occurence of hot pixels.
