Sigma's revolutionary fast APS-C zoom — the 17-40mm f/1.8 DC Art, an unprecedented specification.
The Sigma 17-40mm f/1.8 DC DN Art for Fujifilm X is a revolutionary APS-C zoom maintaining f/1.8 across the entire 25-60mm equivalent range. No other zoom lens maintains f/1.8 at this focal range. The Art designation ensures premium optics. Designed for photographers who want fast-prime speed with zoom convenience on APS-C mirrorless.
Optical performance is outstanding. Sharpness is very good from f/1.8 throughout the range. The constant f/1.8 provides depth of field control and low-light capability previously only available from individual fast primes. Stepping motor AF is fast and quiet. Nine rounded blades produce smooth bokeh. The Art line quality ensures this isn't just fast — it's genuinely sharp.
Fujifilm X mount. Filter thread is 72mm. Weight is approximately 640 grams — substantial for APS-C but justified by the specification. Build quality is excellent Art line. No weather sealing. The unprecedented f/1.8 sustained across the standard zoom range replaces the need for separate 23mm, 30mm, and 33mm fast primes.
Very limited availability as very new. Check AF. A genuinely revolutionary specification — no other zoom maintains f/1.8 across this range. The Art quality ensures it delivers on the promise. One of the most significant APS-C lens releases in years. Essential for Fuji X shooters who want maximum speed with zoom flexibility.
