Canon's original L-series ultra-wide zoom — 17-35mm f/2.8 before the 16-35mm replaced it.
The Canon EF 17-35mm f/2.8L USM launched in 1995 as Canon's first L-series ultra-wide zoom with constant f/2.8. It served professional landscape, architecture, and event photographers before the 16-35mm f/2.8L succeeded it.
Optically good for its era — sharp in the centre with L-series quality. Constant f/2.8. Ring USM for fast, silent AF. The 17-35mm range was the standard professional ultra-wide of the 1990s. Weather-sealed L-series construction.
Canon EF mount with 77mm filter thread. Approximately 750g. L-series weather sealing. Ring USM with full-time manual override. Full-frame coverage. Minimum focus distance approximately 28cm.
Available used at mid-range prices. The 16-35mm f/2.8L replaced it with wider coverage. The 16-35mm f/2.8L III improved further. This original is only interesting at lower prices. Check for smooth AF and clean optics.
