What this lens is and who it suits
The Sigma 18-35mm f/1.8 Art DC HSM mounts on Canon EF digital SLR cameras. It covers wide-angle to normal focal lengths with a constant maximum aperture of f/1.8. The optical design uses 17 elements in 12 groups including five SLD and four aspherical elements. A ring-type ultrasonic motor provides fast, quiet autofocus with full-time manual override.
Behaviour under sustained use
The constant f/1.8 aperture maintains exposure consistency throughout the zoom range from 18 mm to 35 mm. The Hyper Sonic Motor delivers reliable autofocus speed and accuracy during extended shooting sessions. Minimum focus distance remains 11 in across the range, while the angle of view shifts from 76.5 to 44.2 degrees. The lens accepts 72 mm filters via the front thread.
Check before ordering
Confirm your Canon body uses the EF mount and has an APS-C sensor, as this DC-series lens is designed for that format. Verify you can accommodate the physical dimensions of 3.1 x 3.1 x 4.8 in and the 72 mm filter diameter. Note that the lens lacks built-in image stabilization, so steady handheld technique or a stabilized body is required. The aperture stops down to f/22 at minimum.

Questions about this item
How much power does the lens draw when the Hyper Sonic Motor runs all day?
The lens uses the Canon EF mount for power and has no separate power rating; the HSM motor draws minimal current from the camera battery during autofocus.
What camera body must I already own for this EF-mount zoom to function?
Any Canon Digital SLR with an EF mount; the lens covers APS-C sensors at 18-35 mm with a constant f/1.8 aperture.
Will the 72 mm filter thread and 11 in minimum focus distance work with my older EF lenses and accessories?
Yes, the 72 mm thread matches many legacy filters and the 11 in close-focus is compatible with existing EF-system workflows.
