The Zeiss’s autofocus system, of course, isn’t. You’ll want to read some hands -on reviews to get better information about that. The Sigma’s autofocus was quick and accurate on a 5D Mk II and 6D in good indoor lighting, but I didn’t stress test it under difficult conditions or with moving targets.
SIGMA LENS RENTAL MANUAL
After using those, the Canon’s manual focus ring feels like a greased pig. The Sigma Art manual focus ring is really excellent, too - very smooth and accurate. This isn’t a lens review, but for someone who does a lot of manual focus, I absolutely love the smooth, long-throw focus ring of the Zeiss. The other specifications are pretty clear: the Zeiss is really big and really expensive, the Canon is smallest and goes to f/1.2, the Sigma is easily the least expensive and middle-sized. Left to right: Zeiss 55mm Otus, Sigma 50mm Art, Canon 50mm L
The Sigma has 13 elements in 8 groups, while the Otus has 12 elements in 10 groups. The Canon has a simple double Gauss design with 8 elements in 6 groups. The optical design dates back to the early 1980s.Īs always, this isn’t a complete lens review, just lab testing and comparisons on multiple samples.
True, it was released in 2006, but even that was something of a comeback. I choose a beat up and battered two-year-old Canon for the photo below, just to emphasize that it goes into this contest like a prize-fighter coming out of retirement for the fifth time. I added the Canon 50mm f/1.2 into the mix, since I suspect some 50mm f/1.2 shooters are wondering if they should migrate to the new Sigma. The comparison most people are making is with the Zeiss 55mm Otus, because the Sigma Art and the Otus are both newly designed, excellent lenses. I decided I might as well post the results, even though I’m a bit late to the party. Plus, we’ll have our new MTF bench installed in another week or two, and I want to do some comparisons using the bench versus Imatest, so when we got our first seven copies of the Sigma 50mm f/1.4 Art in yesterday I compared them with Imatest. So when we received our first Sigma 50 f/1.4 Art lenses for rental stock I really didn’t plan on posting about it.īut I always think it’s worthwhile to review multiple copies of a lens bought off-the-shelf from retailers.
There are already plenty of good early lab reviews on the eagerly awaited Sigma 50mm f/1.4 Art lens at SLRGear, Lenstip, and DPReview, among others. I suspect I’ll never be on any manufacturer’s “early review copy” list for new lenses.
