FWIW ... after having used the lens out there over the weekend - the experience tells me - once again - that DSLRs and EOS cameras in particular just can't focus accurately with ultra-wides. The margin of error is HUGE and, of course, it was especially bad with this large aperture Sigma lens.
Things are fine with close-ups but for middle-ground scenes (2-3m) things are going down the hill rapidly. The camera is just focusing too far to the rear.
