The wide zoom has a close focus of 11", with the long zoom having a close focus of 3' 2", impressive for a 100mm zoom, which should be good for a nice close-up. A consistent wide aperture matters to a cine shooter, who generally will want the option to shoot the entire scene at a given F-stop, and it's nice to see that the lenses maintain T2 all the way to 100mm, which is getting into the length range where even prime lenses sometimes give up half a stop at the wide end of the aperture. Sigma starts the party with the "High Speed Zoom" range with two lenses featuring a constant T2 aperture on both the wide angle 18-35mm and the telephoto 50-100mm. That all changed with the announcement that they are releasing Sigma Cine Lenses, starting with a high speed zoom line to be released this fall, followed in the spring by a set of prime lenses. Sigma prides themselves at being the largest independent manufacturer of photographic lenses in the world, but they've never before had a cine-specific offering. Sigma, long a leader in mass still photo lens manufacturing, announces their first dedicated cine line of both zoom and prime lenses.
