Rawdigger dynamic range1/7/2023 It is like buying a sports car that could potentially reach 200 mph top speed, but cannot go beyond 150 mph due to having a limiter in place. What does this mean? Well, to put it short, Sony is basically handicapping the potential of the A7 cameras by using lossy compression on RAW files. To keep RAW files smaller, Sony decided to employ lossy compression, which is basically 11-bit of base data, plus 7-bit of delta offset, as detailed in this article by our friends at RawDigger. However, all A7 series cameras, including the A7 II come with a pretty disappointing limitation – they are unable to provide uncompressed or lossless 14-bit RAW data. Rawdigger dynamic range iso#Noise levels are controlled very well and you can comfortably shoot even at ISO 6400 in low light situations, which is amazing. The camera can capture almost 14 EVs of dynamic range, which means you can recover a boatload of information in post when shooting high contrast scenes without losing too much data or introducing a lot of noise. DxOMark ranked the Sony A7 II very close to the original A7 in terms of color depth, dynamic range and low-light ISO performance, so it is safe to assume that the sensor on the two cameras is the same, with perhaps a few small tweaks here and there. Nikon uses a similar sensor on its D750 DSLR and the results speak for themselves, although as I will demonstrate in the camera comparisons section of the review, Nikon processes RAW data differently and its image processing pipeline is superior in comparison. First, the good news – the 24.3 MP Exmor CMOS sensor is wonderful, arguably the best 24 MP sensor in the world today in terms of dynamic range and noise performance potential. Let’s get to the meat of the camera, the imaging sensor.
