How usable is this without live view even as an option? I can understand running without a tripod, but how necessary is LV for focus/composition?
I use mine with a 1DsMkII which has no live view and I have no problems. The optical viewfinder on my camera is quite good though so I can't say how it might be to use on a lesser body.
Keep in mind though that almost any outdoor shot you take with this lens is bound to come out in nice sharp focus by simply relying on the focus gage on the lens barrel or making use of the AF confirmation beep on your camera prior to any tilting or shifting.
Live view might only be more of a must have if you want to achieve a lot of selective focus/blur effects and to that end, the 17 is the least giving of that feature compared to the 24 and 45mm TS lenses.
Cheers!
