of the box. We observed that f/4 to

f/11 produced the sharpest images

throughout the zoom range and the

sweet spot was f/5.6.

The lens produced rather heavy barrel

distortion from 24 to 28mm and pin

cushion distortion at 35mm.

Value for Money

The Sigma 24-35mm f/2 DG HSM | A lens

retails at an MRP of Rs.78,900. At this

price, the lens is reasonably priced. |SP

VERDICT

The Sigma 24-35mm f/2 HSM | A

lens has a very narrow zoom range,

which, in my opinion, will not appeal

to a great majority of photographers

especially since the lens is as heavy as

the Nikkor 24-70mm f/2.8 (non-VR).

We presume that Sigma has been a

little over-enthusiastic in producing the

fastest full frame zoom lens that they

compromised on the utility. However,

considering the fast aperture, this lens

is unmatched in this category.
