Working with Sigma on lens reviews, like this one, I knew the Sigma E-mount primes were coming and the models were just announced. They include 5 Art primes. I linked them where available.
And, what this means is another indication of Sony’s strong market position. Also, an adaptor like the MC-11 is no longer needed to use Sigma’s excellent lenses. While the MC-11 worked perfectly; including most native functions like Eye-AF, it required another purchase to convert lenses from EF to E.
The new Sony E-mount models feature a newly developed control algorithm that optimizes the autofocus drive and maximizes the data transmission speed. In addition, these lenses are compatible with Sony’s Continuous AF (AF-C) and high-speed autofocus, which were not entirely addressed by the MC-11. In other words, using the MC-11, you could get some focus hunting.
So smart shoppers can now get a lens that rivals Sony’s own G Masters in quality for hundreds of dollars less. See my review of Sigma lenses here and below are featured highlights about the Art primes.
Thanks to an autofocus drive control program tuned for each lens and high-speed data transmission, the lenses offer a high-speed autofocus at the same performance level as that of a lens designed exclusively for mirrorless cameras. In particular, in E-mount cameras offering Sony’s Fast Hybrid AF, AF-C mode delivers exceptional subject following performance. Autofocus remains extremely precise even in those E-mount cameras offering only contrast AF.
The lenses are compatible with in-camera image stabilization. The Sony E-mount camera senses the focal length of the lens and automatically optimizes image stabilization performance.
The lenses are fully compatible with in-camera aberration correction, which includes corrections for peripheral illumination, chromatic aberrations and distortion. By matching corrections to the optical characteristics of the lens, this function takes image quality to an even higher level.
Making the mount native to the lens means a more rigid and stable feel to the lens. Featuring a special surface treatment to enhance strength, the brass bayonet mount offers a high-precision fit and exceptional durability. The mount connection area incorporates rubber sealing for dust- and splash-proof construction.
