I've read about rotating on the nodal point of the lens, and there is a really lengthy article on the Really Right Stuff page about all the equipment they offer in regards to panoramas... My head hurts from all that info.
I'm trying to minimize the amount of setup/overlap, tripod moving, etc and it seems like the most efficient way is to go with the Tilt-shift lens. Take one all the way left, take one all the way right and then stitch in PS, right? Or at least a third image in the direct center of the frame...
I've read the reviews on The-Digital-Picture raving about the 24mm mk II over the first version with regards to chromatic aberration and fringing etc... but if a lot of that can be fixed in PS, is it worth saving $1,000+ to go with the mk I over the newer mk II?
