Control, due to the shrinkage of the shoulder screen, some functions need to go into the menu, such as ISO adjustment, it is recommended that we set up a quick ISO adjustment, so that you can not open the back of the screen with the wheel to adjust the ISO. focus point selection is more convenient than the 6D, that 4-dimensional buttons are quite good to use, it is a little small, smaller than the D800 circle, without the AF-ON button is a problem, although you can AFLOCK instead, but for some features party is a little inconvenient. Flip screen is functionally very good to use, low and high camera shooting is very convenient, many occasions are not able to lie down or set up a ladder, flip screen can solve the problem very well, but its not perfect, for a semi-professional SLR, its stability to be proved. 1/4000 shutter is a pain for landscape party, but like to shoot portraits of photographers have little impact.
