Canon EF 70-200mm f/4L IS II USM Review

The Canon EF 70-200mm f/4L IS II USM is a telephoto zoom lens designed for full-frame EF-mount DSLRs, though it also works on APS-C bodies with a crop factor. It occupies the budget-conscious slot in Canon's venerable 70-200mm lineup, trading the f/2.8 aperture of its pricier siblings for a lighter, more compact build and a significantly lower price point at $239 MSRP.

The lens features optical image stabilization, Super Spectra Coating to reduce flare and ghosting, and a DC Micro Motor autofocus system. The constant f/4 maximum aperture provides decent low-light capability and subject isolation for portraits, events, and sports in good light. The f/4 to f/45 aperture range and seven-blade diaphragm should deliver smooth bokeh when working at longer focal lengths and wider apertures.

This lens fits squarely between entry-level telephoto zooms and professional f/2.8 variants. It's a solid option for hobbyists and enthusiasts who need reach and image stabilization without the bulk or expense of faster glass.
