Dustin Abbott has completed the Canon Rumors review of the Sigma 24-35mm f/2 DG Art series lens. He attempted to answer the biggest question about this lens, who’s it for?
Where people may not buy into the Sigma 24-35mm f/2 ART lens is in the “why” department. The limited zoom range is going to cause a lot of people to wonder “why”, particularly when Sigma themselves have both excellent 24mm f/1.4 and a 35mm f/1.4 ART series primes. The 18-35mm f/1.8 ART has proven successful in part because there are relatively few quality alternatives specific to the APS-C market. Part of the challenge for this lens is the fact that full frame owners have a much broader choice of quality options. I own the Canon 35mm f/2 IS, which offers similar image quality at a lower price, much smaller size, and adds an extremely effective image stabilizer and higher focus accuracy. The tradeoff vs. many other 24mm or 35mm primes is that you lose a full stop of light to gain the small amount of zoom. You also get a larger, heavier lens.
