Maybe we're just expecting each new Sigma A/C series lens to produce absolute optical miracles, every time they bring out a new breaking the barrier lens. ................................................................................;;; On the Canon FF 50 MPs sensor (which grabs all lens's resolutions by the throat) it looked to produce very good resolution on the frame edges and corners from F2.8 up and is surprisingly good even wide open where your unlikely to be cheeky enough to ask for crackling corners. The center resolution is not even in question.
One would expect less sharpness on the APSc sensor print size wise.
What you do get is a solidly made FF lens with Sigma's upgraded quality control over decentering, offering a F1.4 aperture on a wide 24mm FL. Add just for good measure no focus shift or OOF fringing. All for a price that doesn't make you wince like OEMs.
From where I'm sitting it looks a nice bit of kit, especially if you been spending the day picking bits of AF gear teeth out of an old Sigma EX lens of which you had to pack out bayonet with cardboard just to get some sort of semblance sharpness on the right hand side of the frame!
Sigma are doing very well now they've up'd the game and that's rubbing off on Tarmon!
