read earlier answer, you must get your exposure" more right because of inferior DR and exposure latitude in Canon"
try to understand the difference and if you expose them "right" (same parameters) you have 14 stops DR in Nikon d800 and about 11,5 stops in Canon , including pattern noise/banding
PS some people was accusing me to use bold letters a week ago . luck above, what was that?
Do you have any real photos taken by yourself with your nikon cameras showing the vast superiority over canon cameras when properly exposed and processed?
Please show me some of your work which would be limited if you shot canon exclusively. Only then may you gain any of my respect lost for you and possibly give your words some weight to others here as well. (This doesn't include test charts and color test's)
