My photography is almost 99% Landscapes and Architecture. I shoot 99.9% of my images from a tripod and almost all of them are shot as Bracketted images to allow me the flexibility to Tone Map if I so desire. Performance at very, very high ISO's E.G. 12,600, is academic. ISO 1600 is the most that I could ever conceive needing and these days I am using ISO 50. What I wanted from Canon was a 16 Megapixel FF body, Live View, top IQ ISO performance to 1600 and 10 Frames per Second. Stephen
