I've been using it for about a week. Completely satisfied. Chose between 550,600,60. I am very glad that I chose the 600ku. Compared to the 60th, the light weight and size is a huge plus for constant use. 60ka is needed only for the rate of fire and for the convenience of prof. use (additional display, additional wheel) The quality of the pictures is exactly the same as on the d7, which costs more than 2 times more. The swivel display is a definite plus over the 550.
