Boasting the superb build, mechanical and optical quality found in the Canon L-Series Lenses and a widely used range of focal lengths, the Canon EF 24-105mm f/4L IS USM Lens is one of the best and most popular Canon general purpose lenses made.

The lens did however have a rocky start, with early models suffering from an internal flare problem , forcing returns and delaying wider distribution. These issues seem to have been solved now though, and certainly the versions we've tested exhibited no problems in this regard.

Useful wide to short telephoto range; Effective anti-shake IS capability; Fast and quiet USM focusing motor; Polariser-friendly internal focusing

Relatively expensive (at list price; Corners slightly soft at telephoto end; 24-70 f/2.8L has better build and focusing; 17-40mm f/4L an affordable alternative

This is a great sharp lens for everyday use, The price justifies the results.

A superb general-purpose lens, Canon's EF 24-105mm f/4 L IS USM is equally at home on the EOS 400D and the 'full frame' EOS 5D cameras, giving a focal length range equivalent to 38.4 to 168mm on the former.

The Canon 24-105/4L IS lens is reasonably high quality, reasonably fast, reasonably wide range, and reasonably light. It is designed for the latest generation of full-frame digital SLRs such as the Canon EOS 5D , ( compare prices ) ( review ).

EF 24-105mm f/4L IS Strengths: This 4.4x constant aperture L-zoom lens provides close to the perfect focal length for event photography (e.g., weddings, receptions) as well as travel photography with a full frame camera.

If your going to buy 1 zoom lens to go with your Canon Camera this is the one to get! I use this with both my 1DS Mark 3 and my 20D. The lens performs great with the IS and I've hand held to a 1/15th of a second, with my Mark 3 and gotten tack sharp photos.

Excellent resolution in the centre throughout the zoom range; Excellent performance towards the edges when stopped down; Great Image Stabiliser; Good build quality; Fast silent autofocus

CA levels towards edges throughout the zoom range a little high

Great lens; excellent Canon L (L = Luxury) quality! The zoom range is perfect for a carry-around lens; when travelling this is likely to be in front of your camera 90% of the time. Build quality is great, feels solid in your hands.

great picture quality; quick focus; not that expensive for L lens
