After waiting around most of the day for my refurbished EOS 5Ds R to arrive from Canon USA, I managed to shoot a bit with that camera and the EF 16-35mm f/4L lens. The 5Ds R is a 50.6MP full frame body which was introduced in 2015. It remains Canon's highest megapixel camera body and is still available new at select retailers. It had an initial price of $3,899 and now sells for $1,499 new and $1,199 refurbished.
I did not use great technique with these photos, all handheld with shutter speeds ranging from 1/2 to 1/10 second. They are also single file images, not HDR composites. A better plan would have been to use a tripod and bracket for HDR processing.
