Sigma 17-40mm F1.8 DC Art @ 28mm | F1.8 | 1/5000 sec | ISO 125 Photo: Richard Butler Sigma's 17-40mm F1.8 DC | Art is a super-fast standard zoom for APS-C mirrorless cameras. It's a slightly wider, slightly longer, appreciably lighter update on the company's breakthrough 18-35mm F1.8 DC HSM lens for DSLRs. As with that lens, the 17-40mm can expand the operational envelope of APS-C cameras, giving a fast equivalent of something approaching a classic 24-70 lens (26-60mm equiv. on most mounts, in this case). Or it can be seen as a tube that comes with a series of relatively rapid primes stuffed inside.

We've also not yet had time to shoot the kind of video project that it should lend itself to. But we have had the chance to shoot it on both Fujifilm's 40MP X-T5 and a 26MP Sony, to see how both systems perform when focusing it, and we're glad to be able to report that it has none of the temperamental nature of its DSLR forerunner in that regard.
