One of the great marketing scams with technical cameras is the pretzelisation on the camera for the ad. You know the one: the camera is contorted like the ABC Television logo.
In reality, for most landscapes/cityscapes etc, you need very little in the way of movements.
With my 72mm, I need bugger-all tilt to maximise DOF. It is so small that I actually have to fight the detent function; it wants to push the front back into the zeroed position…
With longer lenses and/or closer focus, there will be greater pitch to movements. http://www.youtube.com/watch?v=gR4m70xr9mE
is a good video to show how movements (Scheimpflug) can be done.
It's not too difficult to do in practice. You simply need to trial and (correct) error your focus. Put on some tilt or swing. Check focus near and far. If it's not the same, change the angle. Check focus again. Keep repeating until you have little or (preferably) no focus correction between the near and far objects. It really is that simple!
