I would appreciate some advice on tilt-shift. I am considering getting a tilt-shift lens to enable me to get better shots inside buildings, e.g. old churches, where space can be tight and I might normally resort to a hefty bit of perspective correction in pp.
It seems that for my Canon 70D the best option to give a wide enough view would be the Canon TS-E 17mm. This has a (to me) seriously hefty price tag but I would pay it if I am not going to be disappointed with the results. I see myself using the lens largely for its shift capability.
My questions are:
1) Is it even worthwhile pairing such a lens with a crop sensor camera?
2) Is it possible to use the Canon 24mm version (somewhat cheaper and possibly more useful for quite a few of the closer-in shots I also envisage taking) and include the same coverage that can be achieved with the 17mm by creating a stitched image in pp.
3) Is a hand-held light meter the best way to achieve good exposure for such lenses?
