I got here from a Canon 450D to Nikon D300S and I’ve one minor criticism. The Canon allowed me to alter all publicity settings whereas trying by way of the viewfinder and taking pictures in handbook. Within the Nikon, the ISO button format does not permit me to alter ISO whereas trying by way of the viewfinder, whereas having my left hand on the lens and proper hand on the shutter button space. As a workaround, I mapped the ISO sensitivity change to the fn button, and this made every part a lot better. However I nonetheless do not see the worth I am altering to within the viewfinder, i.e. whereas altering the worth by way of the up-down keys, it does not present the change, however after urgent OK (center button within the arrow keypad), I see the brand new worth the ISO has modified to. I am questioning is there a approach round this annoyance, or does Nikon simply anticipate me to make use of Auto ISO, trigger handbook ISO simply does not make sense?
