Get Canon 5DS DSLR at B&H Photo.
Presented in my review of the Canon 5DS R, I show the entire ISO 50 to ISO 12800 series in both color and monochrome.
The exposure was a perfect ETTR exposure, so much so that small areas are starting to blow out in the green channel. The red and blue channels are also very well exposed. No better exposure is/was possible hence this is the most favorable case in terms of minimizing noise; the full dynamic range of the sensor has been utilized.
This series is thus a definitive real world study of the kind of best results one can expect under conditions where there is a wide dynamic range and areas of colors that are more of a challenge (e.g., reddish and yellowish tones) and exposure is absolutely optimal.
Includes entire-frame images up to 24 megapixels (equivalent resolution to a Leica M Monochrom Typ 246) as well as four large crops, again across the ISO range and in color and black and white.
The results are compelling.
