Here's a less rosy look at it from LensRentals.

Doesn't look to be too shabby. Wide-open, and compared to one of the best lenses ever made (in the TS-E 24 L II), it's not as good. But don't forget, it's not even half the price.
Stopped down to f/8-11, the resolution figures look damn nice though. If you want a TS lens for landscapes where everything's in focus, perfect. If you want to use tilt to get more DOF when using wider apertures, not so good. If you shoot Pentax or Sony, it's the best (only) you can get.

Agreed. My primary concern wouldn't be the resolution as much as the build quality. I own the 8mm FE, the 14 2.8, and the 35 1.4. They're all very sharp stopped down and the 35 is even pretty sharp wide open. But the LR writer is correct when he says Roki's are essentially throw away lenses. At least, the primes are. At $200-$400, if they break badly and can't be fixed, get a new one. But the TS at $1000 is hardly in that category. I look forward to further testing in the hands of trusted reviewers like Bryan.
