Dxomark is the leading source of independent audio and image quality measurements and ratings for smartphone camera and lens since 2008. For its lens reviews dxomark uses the following as criteria. If you select a camera youll see a bar of links above the scores scores specifications measurements and lenses tested. Print this tab displays the print performance measurement values and graph derived from a raw image after a normalization step that transforms all images regardless of original resolution. Distortion resolution from the modulation transfer function measurement light transmission t stop vignetting and chromatic aberrations. In dxomark testing we measure only the maximum color sensitivity.
Fortunately dxomark allows you to view more detailed measurements. Dxomark has test protocols that photographers can use for further understanding the scores and methodology used in the tests. I was wondering if the differences in the measures were due to the use of a different noise floor for the computation a different tone curve or something else. A color sensitivity of 22bits is excellent and differences below 1 bit are barely noticeable. Expert news reviews and videos of the latest digital cameras lenses accessories and phones. These scores can give you a rough idea of how a camera performs but theyre too simplified to be of much more use.
Packing a 36mp cmos sensor in a weather sealed body the new k 1 certainly looks like its been worth the wait. Print this tab displays the print performance measurement values and graph derived from a raw image after a normalization step that transforms all images regardless of original resolution. Costing just 1800 body only its the cheapest 36mp full frame dslr currently available saving you 100 compared to the 1900 mirrorless sony a7r and around 1000 cheaper than the 2800 nikon d810 dslr. So id appreciate an explanation from anyone that knows whats going on. Dxomark seems to give different measurements than does imatest and this has piqued my curiosity. As with dynamic range color sensitivity is greatest when iso speed is minimal and tends to decrease rapidly with rising iso settings.
