For maximum flexibility most of our still camera lenses are designed to cover full frame sensors, which means they will also cover crop sensor cameras, but with a 1.5x magnification factor. If you want to have the same field of view on a crop sensor (or Super 35mm) sized sensor, you can use an adaptor with internal optics to remove that magnification factor. The added benefit of these adapters is that those same internal optics can increase the F stop of the lens by approximately one stop. So a Canon 16-35mm f2.8 full frame lens, which on a crop sensor camera would normally be a 24-52mm f2.8 lens, becomes a 16-35mm f2.0 lens with the aforementioned “Speedbooster”. I’ve used this little lens physics lesson to explain the lens in the title. Sigma has designed this lens to only cover crop sensor cameras, and it gets its incredible speed by essentially building a “Speedbooster” element into the lens from the beginning.
We are carrying the EF mount, which with a mount adapter, allows it to go onto crop sensor cameras from a number of manufacturers including Canon’s own C70, RED’s Komodo and Sony’s FS7. It will mount directly to crop sensor cameras with a native EF mount such as Canon’s C100 or C300 series. Having said that, this lens and its big brother 50-100mm were primarily purchased to act as the package lenses that come with our BlackMagic Design Pocket Cinema Camera 6K Pro. One or the other with a 6K, they make a nice natural combo.
This is one of Sigma’s ART series line, which means their very best design. It has a hyper sonic focus motor. Is that good? I don’t know, but it sounds impressive! What I do know is that it autofocuses well with speed and accuracy comparable to Canon’s lenses. Aspherical elements and multi-layer coatings mean a sharp lens with low flare characteristics. Not relying on the optics in someone else’s external adaptor allowed Sigma to optimize every element of the optical chain for great images with low distortion, even wide open. Great lens, come check it out!
