My 1Ds III and 1D MK IV paid my mortgage and kept my kids happy in the fashion stakes so I have no complaints with the gear. However, after 3 years of abuse - the 1Ds needed updating and naturally the 5D III was the choice to select. When you have giant sausage fingers like mine - you have to use a grip otherwise you press 3 buttons at once - so my supplier ensured it came with the grip and the OP is right in the initial assessment - the joystick is in a dog awful low position - but also - 5 minutes using it you see why it has to be lower to fit the design of the 5D III and naturally - as in any profession - you adapt and move on to earn some dollars - a week on and it is second nature - the camera and grip feel very comfortable - so much so that my 1D IV now sits in the bag taking a well earned rest.
This is an example of good adaptability! What do you think of the 5D3 so far, having come from using the 1DS3 and 1D4?
