Cropfactor D-lux 4


Recommended Posts

Technically there is no crop factor as there is no cropping; images taken with the D-Lux 4 use all of the image circle that is worth being used. The image diagonal is 9.2 mm, regardless of the aspect ratio selected, so compared to the image diagonal of a 35 mm camera – if that’s what you wish to compare to –, the factor is about 4.7. Note that the sensor is bigger than the image circle of the lens, so calculations based on the sensor size lead to erroneous results. What we have here is the exact opposite of a crop sensor: Where, say, an APS-C sensor crops the image circle of a lens designed for a 35 mm camera, the D-Lux 4 has an oversized sensor that is even larger than the image circle.
