I know it, and it's fine if you're not shifting. But once you start shifting the lens to, say, 25mm out, for stitching or correction purposes, there's serious vignetting. Of course I shoot a white-plexi shot, but Phocus has to lift the shadows so much that they start to get very noisy and chunky.
Thanks for the input, though.
Not a prob, I'm in your position as well and do considerable shifting. Capture One at the moment appears to be correcting sufficiently. Best of luck hunting one down.
