I have heard repeatedly that the Nikon is not that great, and that the new Canon is awesome, but on Roger's tests, the Nikon actually beats the Canon on some measures, and stacks up very well.
There have been several tests and comparisions, diglloyd (and others) has tested both: The Nikon 24 PC-E is "quite good" optically up to roughly 8mm of shift, beyond that it degrades performance- wise. It has noticeable distortion whereas the canon TS-E II has almost none and can be shifted beyond 10mm with no or very little degradation. The TS-E 24/ II is quite close to a perfect lens, in terms of correction and sharpness. I had it for half a year and got perfectly sharp results even shifted to the Max...
The Nikon - in terms of quality - seems to sit between the old and the new Canon.
One will have to wait for more Samyang samples, but what has been shown is not worth talking about. I'd rather spend double the money for an almost flawless lens instead of getting a flawed lens for half the price.In that case I'd prefer to shoot with a high quality normal lens and correct in Software...
