How are the Canon and Nikon 24-70 2.8 equivalents @ 24?
Don\'t know much about the Nikon other than that is has quite severe CA at 24 mm,
The new Tamron 24-70 2.8 VC delivers very good corners already at f/4. The Center resolution is very good, midframe is good, and corners very good (relatively).
The huge thing about the Tamron is the exceptionally low CA. We are talking lower than the Distagon Z* 21/2.8. We are talking Distagon Z* 25/2 low or Canon TS-E 24 II low.
The distortion is a bit higher than Canon and Nikon.
If size and cost is no object, the reference is the Canon 24-70 2.8 II. It is a bit sharper mid-frame than the Tamron, and the CA is almost as low.
If you stop down to f/11, the sharpness across the frame evens out between those two, and you choos between the lowest CA (Tamron) or the lowest distortion (Canon).
