Canon 344B006 EF 24-105mm f/4.0 L IS USM Lens

This lens is absolutely stunning on a crop-sensor body (I use it with a Canon 60D).I've been using a canon EFS 15-85, which is a superb lens, for quite some time and was very pleased with its results, but I'd had a hankering for the EF 24-105L which I finally gave into once Canon announced their Winter cash-back promotion (£80 back) and I'm so glad I did! In fact I wish I'd bought this lens ages ago, even for full price!The lens is absolutely tack-sharp, even wide open, at short to medium focal lengths, and is very-good/excellent across the board at any focal-length/aperture. Contrast is nothing short of staggering too. The optical quality of this zoom lens leaves me speechless, it's on a par with some of Canon's best primes to my eye, whilst also offering the flexibility of zooming.Some people say that the 24mm wide-end isn't wide enough for a crop sensor body, but I find that outside it's adequately wide for most shots, and the long-end 105mm is a reasonably long medium telephoto equivalent, making this an ideal walk-around lens for just about any situation. Indoors you may want something a little wider, but it's still great for portraits and anything except group shots.The constant maximum aperture is a real boon if you're operating the camera in Manual mode, or you're "spot-metering" by zooming-in to obtain a meter reading (especially useful when using flash), and the ability of the lens to yield such good results even wide-open opens up realms of creativity which aren't available when using less proficient optics and using f/8 to give a reasonably sharp image.The Image Stabilisation is one of Canon's 3-stop equivalent systems, not the 4-stop variety seen on the newest long lenses, but still very proficient and useful. The autofocus uses Canon's ring-type ultrasonic motor which is lightning-fast and ceaselessly accurate.This may be a 10 year old lens design but it find it a first-class piece of glass and can wholeheartedly recommend it to anyone who's after top-spec optics at a reasonable price!

I am using this lens on a 600D along with an EF-S 10-22mm, which seems like a nice combination for a crop sensor. Autofocus is very fast, silent, and accurate. Sometimes I wish for a wider aperture, but the Canon EF 24-70mm f/2.8L is a) twice as much money, b) has shorter zoom range, and c) does not have IS. Tamron SP 24-70mm f/2.8 is closer in terms of price, but still doesn't have the zoom range of the 24-105. Perhaps if you already have (or plan to buy) a 70-200 lens, the Tamron is a better pick. Image resolution is very good, allows considerable cropping. Construction is very reassuring, as many people say: "built like a tank".I really haven't found anything about this lens to be disappointed about!

Purchased to fill a 'focal length' gap in my range of lenses. I have a 16-35mm f2.8L IS, 100mm f/2.8L IS macro, 70-200 f/2.8L IS, 70-300mm f5.6L IS, 300mm f/4L IS and 400mm f/5.6L, so I was missing a lens covering the 50mm range. I considered three options to fit the bill - 24-70mm f/2.8L, 24-70mm f/4L IS & the 24-105mm f/4L IS. I compared all three on a very good review website & with the exception of price, it seemed to boil down to whether or not IS is required and whether you're going to be shooting in low light. I never use a tripod, so was concerned about the lack of IS on the pricey 24-70mm f/2.8L, so then it was between the two f/4 models. I was looking at comments on a forum and someone who had purchased the 24-70mm said that he really missed the extra reach of the 24-105mm. This clinched it for me and I decided to purchase this lens. I took it out for a spin this afternoon & am very pleased with the results. I took some general landscape shots & also a close up of a swan which was a yard or two away from me. I'm satisfied that I've made the correct choice.

An excellent lens. Versatile. Good for portraits, Landscapes, creative and close up photography. The only downside is its weight particularly if fitted to a Canon Full Frame Camera, but you soon get use to it. I have used this with polarisers and ND Filters and the results are always excellent. Recent trials with close up filters turned it into a Macro lens so I would not only recommend this lens but also a selection of filters as previously mentioned. You won't be disappointed.

I have a few Sigma f2.8 lenses but was looking for the next level up with the Canon "L" series. I have tried out the Canon 50mm F1.2L and loved it, so I had high hopes for this lens. The sharpen just is not there. It is not different from my Sigma 24-70mm F2.8, which means I feel like I have thrown cash down the drain. Having said that, it is not a bad product, it just is not sharp enough.

I bought this lens to replace my Canon 28-135 mm which was starting to fell a bit sloppy and had a hairline crack in the case.When I did some direct comparison tests I found the 28-135 was actually fractionally sharper at the centre but this reduced towards the edges, while the 24-105 held it's sharpness all the way. Used with my Canon 40D, this is a useful size for a general purpose lens. I'm not really worried about wide angle use, which is better achieved with a specialist lens anyway.The 24-105 retains detail in the highlight and shadow areas when it is lost with the cheaper lens. But whether that is worth over twice the price will depend on the individual user's requirements. I found the Canon 28-135 IS to be an excellent budget lens, but the 24-105 is certainly a much stronger construction.Focus is quite close for macro work particularly with an extension tube. The lens will not accept a Canon Tele Converter and I haven't tried it with a third party converter.So if you can afford the price, and this lens matches your size requirements, I don't think you will be disappointed.
