Cons: Slow. f/4 isn't too fast, but outside it is fine. Noisy IS. Autofocus isn't spectacular in low contrast or indoors Indoor performance overall RED RING is too sexy.

Pros: Bokeh is creamy, but not exaggerated. The blades are circular. Focal length - I use this on my T3 and I don't mind the wide end. In fact, I prefer the crop in the case of this lens, as I don't notice the distortions. IS Construction - solid, but front heavy on my body (this only applies to certain, lighter bodies). It feels like a massive brick that would hurt whatever it is thrown at more than itself. I've taken this into the snow multiple times this week without problem. Weather sealed (more resistant) Much better than my 18-55mm f/3.5-5.6 mkii is, and CA is a major improvement over that kit lens I get a medium telephoto range on my crop body The color and contrast are very satisfying Fixed aperture and parafocal - more than ideal for movies (although I shoot stills) Versatile for both video- and photography.

Summary: Great lens if upgrading from a kit lens. Don't listen to the arguments against this lens on anything but a full-frame. It offers a great telephoto end and remains moderately wide (enough for most applications). Keep a cheap wide angle if this bothers you. If on a rebel body, it will be front heavy, but will make the IQ shine. More all-in-one than either 24-70, plus a bonus of IS. I didn't have any problems registering my imported model under C. USA's warranty, and my seller also provides a 1-yr warranty (thus, I have two warranty services active) The discounted price appeals to those with a lower budget and (stereotypically) cheaper bodies. If they're looking for as much awesomeness they can have into one lens, due to limited funds, this is a good introduction into the L-lens series.

Cons: Image quality suffers a bit compared to other L zooms in the corners, although not bad by any means. Rather big and heavy for a relatively slow standard zoom, though smaller than the competing offering from Sigma. IS is good, but less effective than that of more modern L lenses. My unit suffered from lens creep, which stopped after a warranty repair. Minimum focus distance is a bit long, reducing convenience.

Pros: 24-105 is a very convenient range; much more versatile than 24-70. Good (not fantastic) image quality throughout the range. AF is fast. Built like a tank, resistant to moisture and dust.

Summary: This lens is not spectacular, but a solid, dependable performer; for all the complaints users have about it, it's still the best in its class. Great for travel and other situations where swapping among a set of better performing but less versatile lenses isn't practical.

Cons: the noise of the IS!!!!! zoom ring too small and at the wrong place, vignetting

Pros: good size and construction, sharp at all focals, instant autofocus

Summary: in my opinion, the best general purpose lens on the market

Cons: Bulky & heavy Extention (slide) can not be fixed for transprot

Pros: A very valuable alround zoom lens. Very good optical quality. Well build.

Summary: I use this lens on full frame. On crop I prefer the 24-70. If you do not need the 2.8 (24-70) this is a more versatile standard zoom. For sure the some distortion can be found at especially the wide angle and. But for a lens with this zoom range it is acceptable. Optical quality is very good, flare well controlled. Bokeh is good but not perfect. (If you focus on shouting portraits maybe this is not the correct lens. I use an 85 mm and 70-200 for portraits.) If I go out with my camera 'light', this is the lens that I put on a full frame.

Cons: Perhaps a minor bit of flare.

Pros: Price, quality of build, accuracy of color and focus, light weight

Summary: A simply excellent lens, completely appropriately labeled L.

Cons: bad CA at wide angle in some lighting conditions

Pros: good range and build quality

Summary: reasonably sharp overall

Cons: Heavy distortion at 24mm, lateral chromatic aberrations, flare and lack of contrast when used in studio with strobes.

Pros: Sharp, useful focal length, excellent build quality, IS

Summary: Good as a walk-around lens, but if you plan to use it in a studio buy something else.

Cons: No zoom lock - tends to go out.

Pros: Internal focus. AF (FTM) fast, quiet and accurate. Good and safe IS Superb build, mechanical and optical quality. Weather sealing. Nice bokeh

Summary: In the last two years, my favorite standard lens on the APSC Raltiv large, thus very convenient to use.

Cons: Compared to primes, this is bulky, heavy and intimidating with the big front element. Filters are expensive. Quite significant lateral CA and distortion.

Pros: No longitudional CA and very sharp everywhere. IS is effective. Good range of focal lengths.

Summary: Great for on the fly photography, but I prefer primes for the smaller size and weight and more flexible aperture. Friends are more cautious in front of such a big lens than with a prime. It's a very capable and flexible lens with no optical flaws (after post-processing) if you're okay with the weight and size.

Cons: disortion FF 24mm

Pros: sharp, good colour, range FF, 1:4 close focus 105mm APS-C 24mm also good; ideal landscape set with 10-22

Summary: perfect compromise on waight size and range for FF

Cons: too easy sliding

Pros: very good image quality both at 5D MII and 50D

Summary: very good and a reasonable price when bought as a kit lense

Cons: Big, heavy. Max aperture is only f4. Sharpness is not top. 24mm for APSC is not enough wide.

Pros: Build is very good. AF is fast. IS is also good

Summary: Not recommended for APSC body.

Cons: Maximum aperture 4 is not very good for this lens.

Pros: Great Optical quality

Summary: I recommend as a perfect walk around lens.

Cons: Price if not from kit

Pros: Everything: Range, IS, build quality, sharpness, USM...

Summary: Excellent. My previous lens was 17-55 on 7D. Now, in FF, i've the same feeling.

Cons:

Pros:

Summary:

Cons: At 24 mm on FF lots of vignetting and barrel. After 3 years the lens began to slide from small to longer when holding the lens down, when your walking for example. Very annoying, so the build quality is not that good for an L lens. They told me it can be fixed, but only for a limited amount of time.

Pros: Small and light in comparison with the 24-70 F2.8, much more a walk around zoom. Very good IS and optical performance better the the 24-70 F2.8, but no mach with some primes.

Summary: Best all round zoom available, do not miss the F2.8. For that I take a prime.

Cons: not good for apsc - not wide enough

Pros: solid, good useful common range, IS, light weight, resolution meets pro. standard. No field curvature issue like 24-70L

Summary: must own for FF owner unless using primes

Cons: Image Stabilizer has no panning mode. Slow aperture. Rather large and heavy. Expensive.

Pros: Very sharp, even at maximum aperture (f4). Wonderful colors, they really make this lens standing out! Very solid build.

Summary: This is fantastic lens, not perfect, not as sharp as some prime lenses, but the beautiful color rendition and the wide range makes this lens my choice number one when going for a trip.

Cons: F4 not fast enough. Heavy distortion at 24mm. Mediocre bokeh and rendering. Vignetting and CA on FF.

Pros: Versatile. Weather-resistant. OK image quality. IS. Although it is generally thought of as a FF lens, it is actually better on a crop.

Summary: Compromise, 17-55 IS + 135 L would be a better choice.

Cons: can't find any

Pros: Best walk-about lens I know of

Summary: Just buy it!Fabulous

Cons: heavy Barrel and CAs at 24mm,anyway my favorite focal length, soft at 105mm, by and by Lens zooms out when holding perpendicular

Pros: well working IS, good zoom range, constand f4 aperture, fast autofocus

Summary: top Kit Lens especially for full frame!

Cons: IMPORTANT NOTE: This lens is Dr Jekyll on a crop and Mr Hyde on a full frame. I'm on full frame. - Overcorrected (bad bokeh) - Barrel distortion. - Vignetting. - CA

Pros: - Range. - Good colors. - Sharpness. - IS. - Fast precise focusing. - Weight.

Summary: Very good on a crop, but be careful if you want to upgrade to full frame: - Had to fix huge barrel distortion on all wide shots (can be fixed in post-processing but decreases IQ and requires cropping). - Had to fix vignetting on most shots (easy fix). - Had to fix CA on most shot (easy fix). - Did not like the bokeh, this lens is awfully overcorrected (manual fix and huge waste of time). Synopsis: Replaced with 24-70L.

Cons: You don't get wide angle on cropped sized sensor cameras. IS a little noisy. It's not f2.8

Pros: Focal range from 24 to 105 is very good for FF cameras. Great USM focusing. Build quality superb. Optical performance good but not excellent. IS very usefully. Not very heavy.

Summary: Very good lens. I wish it has f2.8 with the same focal lenght

Cons: loses focus sometimes,in low light AF sometimes stops responding to shot button(i then have to change zoom and it starts working ok again)

Pros: suberb image quality,build to last

Summary: great lens for both amateurs and profesionals,would reccomend to anyone
