Canon EF 24-105mm f4L for cropped-frame bodies intro The Canon EF 24-105mm f/4L IS USM was announced in August 2005 as a 'lightweight' standard zoom lens for professionals. Introduced on the same day as the EOS 5D, it's an ideal general-purpose lens for Canon's full frame bodies, although has also become a popular option for owners of Canon cropped-frame bodies like the EOS 400D / XTi and EOS 40D.

A pretty good pretty fast mid-range zoom lens with image stabilization for Canon's full-frame digital SLRs.

This has been one of the most-requested lenses on the site for us to test, so we're very pleased to finally be able to share our test results with everyone. - And what a lens it is! This will come as no surprise if you've read the glowing user reviews below, but it's always good to see our test results fall right in line with users' experiences.

The EF 24-105mm f/4L IS USM is one of Canon's high end L series general purpose standard zoom lenses and the only such lens to feature image stabilization. It requires some serious financial commitment but so do the full frame bodies this lens is meant for.

Although this L lens has been out for a few years now, we still get a lot of questions about it, especially given that it is one of the "kit" lenses that comes packaged with the 5D Mark II. It has a largest aperture of f/4 but benefits from IS.

Avoir un zoom avec une bonne amplitude (généralement grand-angle et petit télé), c’est pratique et cela évite bien souvent d'avoir à transporter un sac photo lourd et encombré d'optiques fixes. Avec une ouverture constante à f/4, le zoom de Canon s'avère assez compact et léger.

Canon users who cannot afford to spend around £2,300 on the latest 24-70mm f/2.8L II USM lens might find solace in the fact that for much less they can buy a wider-range zoom with the same pro-spec pedigree. Admittedly the 24-105mm is an f/4 lens but it benefits from Image Stabilisation, which more than offsets the lack of a wider aperture in respect of exposure.
