We are personally fans of shooting with prime lenses, but you often ask about a single lens that could replace several primes on a film set. Budget is always a consideration, of course. We spent a long time deciding what to choose. We had previous experience with the Canon 24-105 L, which is, to put it mildly, hopeless. Browsing Vimeo we came across samples shot with the Sigma 24-105 ART and said: WOW — you can shoot amazing footage with this! And here it is in our hands — a brand-new Sigma 24-105 ART with Canon mount. This is a seriously solid piece of glass. The stabilisation works brilliantly for video. It is sharp wide open. It covers full frame. Really — if we are not shooting in the dark, this lens will replace several of our primes. It even works for Macro. See for yourselves.
