Features: Professional quality standard zoom with a constant f4 maximum aperture. Image stabilisation gives around 3 stops leeway from camera shake. Front element does not rotate during focusing so easy use of filters. 77mm front element common across many L lenses allowing easy interchangeability of UV filters and polarisers. Compatible with EF and EF-S lens mounts. Comes with a nice soft lens pouch and the petal shaped hood is included. Build Quality: Excellent. Typical L lens build. Very solid metal construction, weather sealed and both the zoom and focus rings have a lovely slick action making precision adjustments easy.

Kit lenses in the past haven't been all that great. In fact the words, when used by some imply a derogatory sentiment. Adequate , acceptable etc. This really doesn't apply to the 24-105mm at all. It preferred use of lens among a few professional photographers I know and I myself use it a lot. One of its best features is obviously image quality. Contrast and colour are two really features of this lens. It's not quite as sharp as other lenses when stopped down all the way, and for low light situations I can't recommend this lens over the 24-70mm or a good prime. However I've taken some great landscape shots with this lens and like-wise some great zoomed in shots ...  Read the complete review

Overview: This lens is a brilliant all rounder, with great build and ergonomics, a very useful range of focal lengths (more on this below) and a good list of features like IS and USM to complete the package as a super kit lens - i.e one that you can use in a variety of situations but which delivers top notch image quality and control over aberrations and flare. There may be lenses that offer greater maximum aperture, or have a greater range, or are wider, more telephoto, etc, but there really is nothing that can compare with the 24-105mm f4 in general multipurpose usage, a huge bonus for areas such as event ...  Read the complete review

This lens still makes great images, even on an unforgiving camera like the 5D MkII. And it works really well on the crop cameras too, though 24mm isn't really wide angle at 1.6x. Sure, there's some corner darkening at wide angle settings and the wider apertures on the 5D, and it does get sharper stopped down a bit, and it doesn't feel like it's made of solid granite either. But as a working standard zoom it is excellent: lovely colour, excellent sharpness and very little distortion. The IS is good too. And it doesn't weigh a ton either. Handling is as you'd expect, and although the lens is plastic it doesn't feel slack. But the best bit ...  Read the complete review
