Hi,
Thanks to everyone who responded.
A few comments..........
Agreed that the Canon 24mm TS lens is an excellent lens. I can't afford one though. I'd also agree that a dedicated TS lens will offer better coverage than an adapted FF lens. I don't know that you can say that there will necessarily be a fall off in IQ. There will with some and not others. This will depend substantially on the lens used, its image field shape, the extent to which movement runs it out of its high quality image area, and the sensor's characteristics for capturing light at different angles. (Note that this latter characteristic would also affect the capture of light from any native X mount TS lens).
This isn't simple - one needs to choose an FF lens carefully and really know what to expect. Whatever FL you're considering it needs to have a well corrected image field that is sharp from corner to corner. Very fast lenses that display curvature of field and vignetting, and need to be stopped well down to get sharp corners aren't going to be the most useful lenses to adapt to movements. Slower lenses with a flatter field and more even characteristics are more likely to do the trick.
My main interest in using the adapters wouldn't be for shift - you don't get an awful lot of shift movement from an FF lens used on APSC before you run out of coverage, or at least quality coverage, and it doesn't give you a strong effect before that happens. You can also adjust keystoning quite well in PP. I'm very interested in tilt for landscape usage. You can't get that from software. This typically requires very little movement at all - usually, 2-3 degrees of tilt will do everything you need and you don't come close to running an FF lens out of coverage on APSC.
I'm dubious about the rumor and won't be holding my breath. Quite apart from the low sales volume and the high cost, a problem for me would be that I'd actually be interested in tilt with a FL longer than 15mm - NB that both Canon and Nikon have three or four TS models each for the very reason that the wides are better suited to shift (for architecture and interiors) and the longer lenses to tilt. The wides inherently have excellent DOF anyway.
Thanks again, cheers, Rod
