photozone.de about the EF 24-105mm:

Regarding its equivalent zoom range (39-168mm) on an APS-C DSLR the Canon EF 24-105mm f/4 USM L IS may not be the most sexy lens here but its performance figures are very impressive nonetheless. In fact the resolution results beat those from the EF 24-70mm f/2.8 USM L and match the EF 28-70mm f/2.8 USM L with its much more conservative zoom range (but higher speed). There’s a slight decrease in performance at 105mm but even here the quality remains on a very high level. As to be expected from a modern Canon L lens the construction quality is up to pro standards matching its fasters cousins. The lower price tag plus the extra IS should compensate the slightly more moderate max. aperture for most users. Is it a perfect lens then ? Well, there’re also downsides like pronounced barrel distortions and higher than expected CAs at the wide-end of the zoom range. However, the package remains extremely attractive if you can live with the rather unattractive zoom range on an APS-C DSLR – similar to other 28-xx or 24-xx zooms this lens is really more meant for 1.3x or FF (D)SLRs.
