LensRentals on two new Sigmas - so-so and oho!
#7
The sharpness is one thing. To manage to get it on the sensor with all the limits of DSLR AF (in terms of narrowing the single AF focuspoint) is a different story. Sigma needs to simulate non-existing lenses and tell the AF-unit a more or less correct acceleration.

 

Although this lens is great for sure, the pleasure of using it with a DSLR will be limited. The wider a lens (in double sense, here it is "wide aperture" and "ultra-wide-angle"), the more difficult it is to AF. Using that lens in lowlight situations wide open should not be done with too high expectations and best be done with LiveView. It's a perfect lens for Sigma's own mirrorless sd quattro/-H (which totally sucks in lowlight...) but the DLSRs will have to chew on that one.
