![]() That’s still excellent, although technically the Nikon has slightly better color sensitivity, which might be noticeable in the two cameras’ output in areas of smooth transitions. Even then the Sony measures 26 bits, just 0.3 bit lower than the Nikon, while the maximum color depth of the Canon EOS R5 sensor is 25.3 bits at its base ISO. In turn, there’s no benefit in terms of noise or color depth to be gained by dropping to ISO 50. With a lower and “real” base sensitivity of ISO 64, as opposed to a base of ISO 100 for both the Canon EOS R5 and the Sony A7R IV, the Nikon Z 7 II has the edge and achieves the highest color depth of the three, measured at 26.3 bits.īoth the Canon EOS R5 and the Sony A7R IV have an “extended” ISO 50 setting shown on the graph below, but essentially ISO 50 and ISO 100 are the same. While the Canon is touted more for its mix of stills and video and possessing a mild AA filter as a result, its pixel count is high enough for it to be comparable to the landscape-oriented Nikon Z7 II and A7R IV cameras. In this comparison we’ll look at the latest high res model from Sony, the 61MP Sony A7R IV, and the 45MP Canon EOS R5. ![]() Although a measured value and not an actual ISO setting, it’s a good way of comparing low-light sensitivity between sensors. Not quite so strong but still very good is its low-light ISO (Sports) measurement of ISO 2841. The Nikon Z7 II sensor has excellent -practically class-leading - maximum color depth and dynamic range, measured at 26.3 bits and 14.7 EV, respectively. This also positions the Z7 II just behind the two “cropped’ (44 x 33 mm sensor) medium-format models at the top of our database, though the difference of one or two points in terms of overall “ sensitivity” is obviously very small. The Nikon Z7 II achieved an overall DXOMARK sensor score of 100, which is a slight improvement over the model it replaces and puts it in joint 1st place in our sensor ranking for full-frame sensors, alongside the likes of the Nikon D850 DSLR, the Panasonic Lumix DC-S1R, and older Sony A7R III mirrorless models.
