I bought this lens partially for it's versatility, but the timing of the purchase was to shoot pictures for a friend's wedding. I tested the lens out the week before and it worked fine and I ensured it was compatible with my canon cameras.

I bought this zoom in 2005. I did not like the 24-70 F2.8 to walk around. To big. The IS is incredible, IQ is oke and I love the range. That 35 mm extra at the end is very nice. I still think this is the most versatile zoom there is. Go on holiday, take this zoom and a EF 50mm F1.2L with you.

Very nice relative small and light walk around lens with perfect range on FF; If you chose one (zoom)lens to take along this is maybe the one; IS is nice

Nothing special, F4.0 but that why it is small and light; Construction failure, my copy creeps like mad; I put an elastic string around the zoomring, that helps; But a lock would have been nice

I have had the lense for 3 weeks and during that time have used it both in the field and for some bench work with flowers. I have been very happy with all aspects of this lense, except the weight and I knew about that going in.

Consistent Output; Quick Focus; Rugged; Sharp Focus; Strong Construction

Heavy

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

none

This is my first L lens and I have a slightly mixed opinion so far. The build quality, focus speed/accuracy and general image quality seem fantastic. However, I have not found the sharpness to be quite what I hoped for; on center it's similar to my previous non-L tele, and not as good as my...

excellent image stabilization; Good build quality; Quick Focus

Heavy; less sharp than hoped

Packing was good. got a leather bag and lens hood free with this. I have been using this and have not faced any problem so far. I am not able to register this lens on canon india website. I am still figuring that out.

The combo Canon 5D MK2 and Canon 24-105 mm I use a lot. But, it must be said, files made with a Canon 70-200 2.8 II look crispier. Futhermore, bokeh of the 24-105 is pretty bad. Here my complete story: www.camerastuffreview.com/en/component/content/article/57-test-canon-24-105-is

Low vignetting Fast AF Handy zoom range· Seal against dust and water

Strong distortion at 24 mm A bit too high chromatic aberration at 24 mm Not a very nice bokeh Hefty purchase price in relation to moderate resolution in the corners at 24 and 105 mm

The Canon EF 24-105mm f/4 USM L IS produced pretty good quality figures in our tests. The resolution is generally very high throughout the tested range with the exception of 70mm and 105mm @ f/4 where the border quality tanked somewhat - this may originate in a slight centering issue of our test...

The Canon EF 24-105mm f/4L IS USM ($999.99) is a pricey lens in the company's premium line of L-series glass. Its design is appealing on paper: a 4.4x zoom with a maximum f/4 aperture throughout its range, a tough, dust- and splash-resistant design, and a close focus range that projects images onto...

Long zoom range; Fixed maximum aperture; Solid L-series build; Excellent sharpness at wider angles; Optical stabilization; 1:4.3 macro magnification

Heavy distortion and noticeable vignette at wide angles; Very soft edges at longer focal lengths; Pricey

The Canon EF 24-105mm f/4L IS USM ($999.99) is a pricey lens in the company's premium line of L-series glass. Its design is appealing on paper: a 4.4x zoom with a maximum f/4 aperture throughout its range, a tough, dust- and splash-resistant design, and a close focus range that projects images onto the sensor at about one quarter life-size. At wider angles it's quite sharp, albeit with dimmed corners, and if it maintained that level throughout its range we'd recommend it highly. But image quality falls off as you move beyond 50mm. If you're in the market for a 24-105mm, you're better off with our Editors' Choice, the Sigma 24-105mm F4 DG OS HSM. DesignThe 24-105mm measures 4.2 by 3.3 inches (HD), weighs about 1.5 pounds, and supports 77mm front filters. Like other L lenses it has a rubber gasket around the lens mount and, when coupled with a front filter, is protected from dust and splashes. A lens hood and carrying pouch is included, along with standard front and rear caps. T...

The Canon EF 24-105mm f/4L IS USM lens delivers strong sharpness at wide angles, but image quality really suffers when zoomed in—overall, it's priced too high for the performance it delivers.
