The L-series is Canon's flagship professional lens range, designed to include outstanding image performance, ultimate operability and weather resistance. The EF 24-105mm f/4L IS USM offers a lightweight alternative to the renowned EF 24-70mm f/2.8L USM. offers the highest possible optical quality with no change in aperture over the full focal range of the lens. This allows photographers to set exposure at the widest aperture and zoom all the way through to 105mm without having to vary the shutter speed. Image Stabilizer (IS) dramatically reduces image blur caused by camera shake. Gyro sensors detect unwanted vibrations, triggering the corresponding movement of a correcting lens group perpendicular to the optical axis. This alters the light path, returning the image to its correct position on the sensor or film plane. The 3 stop advantage means that photographers normally shooting a 105mm lens handheld at 1/125 sec can obtain a shake free result with a shutter speed as low as 1/15 sec, for vastly extended options in low light conditions. The ring-type USM motor found in the EF 24-105mm f/4L IS USM employs ultra-sonic frequency vibrations to drive auto focus with unrivalled speed and near-silent operation. A powerful CPU and improved AF algorithm contribute to speed performance. Good holding torque stops the lens with precision and accuracy, the instant it arrives at the correct focus point and without overshoot. Photographers can choose manual focus instantly and at any time simply by moving the manual focus ring without first having to switch out of auto focus mode. Circular aperture producing attractive background defocus Inner focusing, ring USM and new AF algorithms for fast and quiet autofocusing Manual focusing enabled even during AF mode (full-time mechanical manual focus) Only environmentally friendly lead-free glass used in lens construction Filter diameter 77 mm / Dimensions (dia x len)

I was debating getting the 24-70 or this; I got this, and so far I am not disappointed. I like IS and don't often use wider apertures; besides, I already have a Tamron 28-75, which is a very nice lens, and much lighter than the 24-70.
Anyway, the 24-105 really does make a good "walkaround" lens, and the IS is very cool (just give it a second to kick in when you push the shutter halfway). On a 5D, the range is very useful, and I combine this with a 70-300 IS, which is also very nice on a 5D.
Some will complain about lens distortion, which this lens has at the extreme ends, but that is easy to fix in DXO or photoshop lens correction utilities. Many pictures will not need it.
The thing I have seen is that with wider angle lenses (in general) is that it matters where you point the camera, in terms of perpective control. For example, when shooting a building, pointing up (to get the top of the building in view) creates a lot of perspective distortion; I will need to back up so I can keep the focal plane vertical or get a tilt-shift lens (which I may do, anyway).

This is my daytime walkaround lense. The range is pretty good with the crop factor on my xsi. Great build quality, nice color, and contrast. No complaints - you really do get what you pay for here.

I actually owned the Canon EF 28-135mm f/3.5-5.6 IS USM Standard Zoom Lens for Canon SLR Cameras before this lens which I used as a walkabout lens on my 40D. Then I upgraded to the 5D, which can be unforgiving on less-than-"L" lenses and I really noticed the bad IQ with the 28-135.
I've owned this lens over a year now and have to say the 24-105 image quality is superb, and build quality is what you'd expect from am "L" lens. I wish the lens was faster like the Canon EF 24-70mm f/2.8L USM Standard Zoom Lens for Canon SLR Cameras but I guess what you give up in speed, you gain in reach. Since I find myself zooming in a lot, it's more useful to me than the 24-70.
There is some slight vignetting at 24mm especially wide open at f4. I can't complain much since I shoot raw and just use the slider in the "lens correction" portion of ACR to correct it.
My one and only complaint about this lens (why only 4 stars) is the lens hood doesn't seem to fit property. It's very tight to get on and off, I almost worry about the long-term effects on the turning portion of the zoom, but I try to be careful.

I am an amateur and this is my first L lens. If you could get only one lens, THIS is the one!
The pictures and videos look great.

I had tried this lens first on the 5DMII and thought the IQ was terrific. I then tired it on the 40D and although not as great as on the 5DMII the difference from my non "L" lenses was appreciable. When I purchased my 7D I was hoping this was the kit lens so that I could take advantage of the discounted price, but unfortunately it wasn't part of the package. I payed full price for it and that is my only complaint. The IQ doesn't seem to be as good on the 7D (a cropped sensor) as is on the full frame 5DMII, but is still much better than the 17-55 mm that I used as my everyday lens for the 40D. For the price, I think it could have been better than an f/4.0 -especially for indoor low light situations. It's quiet and focuses quickly. Overall, I think it's a great lens and if you can swallow the price then you won't regret getting it.
