Canon's premium APS-C standard zoom — 24-136mm equivalent with IS and USM, the best EF-S walkaround lens.
The Canon EF-S 15-85mm f/3.5-5.6 IS USM launched in 2009 as Canon's premium standard zoom for APS-C DSLRs, covering an impressive 24-136mm equivalent. It was widely regarded as the best non-L standard zoom for Canon crop-sensor bodies — a serious step above kit lenses.
Optically very good — significantly sharper than the 18-55mm kit zoom with well-controlled distortion and chromatic aberration across the range. IS provides approximately 4 stops of stabilisation. Ring-type USM motor delivers fast, silent AF with full-time manual override.
Canon EF-S mount with 72mm filter thread. Weighs 575g. No weather sealing. APS-C coverage only. Minimum focus distance 35cm. The 15mm wide end (24mm equiv) is wider than most standard zooms — a real advantage for interiors and landscapes.
Available used at mid-range prices. The wide 24-136mm equivalent range makes this one of the most versatile Canon APS-C lenses. Nothing from Canon has directly replaced it in the EF-S lineup. Check for smooth zoom action. An excellent single-lens solution for Canon APS-C shooters.
