An interesting innovation.

Sigma has just announced an 18-35mm zoom for APS-C sensor DSLRs with a fixed maximum aperture of a speedy f/1.8. It works out to 27-53mm full frame equivalent.

It’s no lightweight at 29 ounces – 5 ounces heavier than the stellar 35/1.4 – but the finish appears to be the same, meaning excellent. Like that prime, the new optic will be programmable using Sigma’s dock. I would guess pricing at $900 for the lens and under $100 for the dock. The lens comes in Sigma, Nikon and Canon mounts. I’m sure my D2x would love one, but I am very happy with the inexpensive 35/1.8 Nikkor G prime.

It’s good that an independent maker can challenge the big boys on both quality and price. It seems that true innovation is mostly coming from Sigma and Fuji today.
