I'm ever so slightly suspicious of this very quick and dirty test since I did see some poor corners with them on the A900, ...


It looks the like the worst DT lens for FF framing is the 35mm f1.8, which has black corners, but these disappear with 1.1x crop around f4 and 1.2x crop at any aperture, which is a lot better than the 1.5x crop used in APS-C mode. Some slight CA visible at 100% detail (~30Mp...) but not as much as I've seen on some Minolta lenses. With 16:9 selected no digital crop/zoom seems to be needed so that's an option too.

I've almost always used the DT lenses with jpegs in camera and corrections on (and the zooms need that ...) but I'm surprised how little correction the DT primes need. Good optics for the original price.
Miranda F & Sensorex, Sony A7Rii, A58, Nex-6, Dynax 4, 5, 60, 500si/600si/700si/800si, various Sony & Minolta lenses, several Tamrons, lots of MF primes and *far* too many old film cameras ...
