Canon EF 28-135mm Lens

The Canon EF 28–135 3.5–5.6 IS USM is a "standard" zoom lens that was introduced in February, 1998. The lens has a 4.82x zoom range and is based on the EF Lens Mount and works with all film and digital EOS cameras that support this mount.

The lens features 2nd-generation image stabilization (IS) technology, ring-type USM with full-time manual focusing and a non-rotating front element, however the barrel does extend with zooming. The lens uses a six-blade aperture, and contains a single aspherical (molded, not ground) lens. Closest focusing distance is approximately 50 cm (19.2 inches).

The lens is generally considered a mid-range performer, with a good value to performance ratio that makes it popular as either a starter lens or an upgrade from lower quality lenses often purchased with a camera body. The range of zoom plus the Image Stabilization (IS) feature makes it an attractive walk-around, outdoor lens for general use. As a relatively slow lens, the usability in low light or indoor/no-flash situations is marginal, however this is where the IS regains some of that margin for some situations.

Although labeled as " Macro" on the lens and in some literature, this is not a true macro lens and cannot reproduce the subject image at 1:1 ratio on the film or image sensor, as with the Canon EF 100mm lens for full-frame bodies or the Canon EF-S 60mm f/2.8 Macro USM lens for EF-S bodies with a 1.6 crop factor. There is a Canon EF 50mm lens that produces a 1:2 maximum image ratio and is advertised as a "compact macro," which is also not a true 1:1 macro but may produce adequate results in some applications. Comparatively, the EF 28-135mm lens has a maximum reproduction ratio of 1:5.3.

This lens uses the Canon EW-78BII tulip-style lens hood.
