Product Description

From the Manufacturer

24mm lenses are the entry into ultra-wide angle photography and this lens is the ideal starting point. It is extremely sharp and offers superior correction of linear distortion, and its f/2.8 aperture makes it easy to use with slow, fine-grain films or in low light. It focuses as close as 10 inches (25cm), and for many photographers gives the ideal combination of a wide-angle "look" without excessive perspective distortion.

Another superb ultra-wide-angle choice, with floating optics for superior performance throughout its focus range and a fast f/2.8 aperture that makes it a great alternative to a zoom lens for low-light shooting. Its rear-group focusing system reaches down to less than 10 inches (0.25m).

Wide and Fast
If you need an ultra-wide angle and a large aperture, one of the following lenses will fit the bill. Ultra-wide-angle lenses can capture scenes beyond your natural field of vision. The EF 15mm f/2.8 Fisheye, the widest of them all, has a 180∞ angle of view. For more normal-looking wide-angle shots, there are longer wide-angle lenses up to 35mm with the maximum aperture you need.

4.0 out of 5 stars Bang for few bucks... May 14, 2005

By Careful Critic

This is a cheap lens - old design, very plastic - that can prove terribly useful for those on a budget who want a wider perspective, especially on 1.6x crop factor dSLRs.

I learned about "cheap" with this lens - broke the focus ring the day after delivery. But I blame myself too, and the replacement's given me no trouble, though I think my first one was a bit sharper than the second. (Update: calibration of the replacement optimized my performance to match or exceed that first one that I broke. It now performs *very well* wide-open at f/2.8, and beyond belief at f/5.6.)

By many standards, this lens will match or exceed zoom lens of comparable price (as a prime lens should). Autofocus is a little buzzy, but the main time you'll notice is when it loses its bearing and suddenly lurches way off target. Mostly, focuses quickly enough and well. Some chromatic aberration in worst-case scenarios, but nothing awful or unexpected. Vignetting, even on a 1.6x crop, can be noticeable, mainly in sky shots, but gradual rather than sudden. (Might be unacceptably worse on a full-frame camera.) Undue distortion seems minimal - haven't really checked but also haven't really noticed, if you see what I mean. Flare seems average, perhaps better than one would expect from such wide glass. (I've never had a shot blown out, even with the sun in the shot.) Bokeh is nonchalant, not dreamy but never intrusive.

But at the price, the positives make up for the negative and "average" tendencies. It's vibrantly colorful and contrasty almost to a fault. Hard light is a little more challenging with this lens, a little more tricky to balance exposure between highlights and shadows. It can be softish wide-open, but very unobjectionably - have rarely regretted shooting at f/2.8. My main lens is a 50mm f/1.4, and switching back and forth on the same aperture setting is perfectly functional in practice. Lose a little crisp for taking in four times as much space, and that's a trade-off I can run with. (Their filter threads match too.)

Before calibration, my second sample got "plenty sharp" by f/4, and "stunning sharp" at f/5.6 or beyond. Now, I never find any complaint at f/2.8, and frequently get my breath taken away at f/5.6. However, other reviewers around the web have verified something I've noticed - the focus is more consistently crisp when focused out to infinity (which isn't far) than when aimed at nearer subjects. For any kind of scenic photography, I recommend setting the focus to infinity and then flipping to manual focus to lock it out there, for easiest and most reliable results.

"Crop factor" over-simplifies the effect of mounting a wide-angle lens on a 1.6x camera. Yes, the field of view will match 40mm on a full-frame, but the perspective will not, because you'll be closer to your subjects. Shooting live subjects (like bands, models, or street life) will require a learning curve, so beware mission critical work before you've broken yourself in so you can anticipate its exagerations.

That said, I bought this lens primarily for "head-to-toe" model shooting in my modest studio, and it's been a real asset. Interestingly, it tends toward a very useful "slimming effect" that makes hippy girls look more slender and shorter girls more ambiguous in height. This happens if you're filling the frame with them and standing with your lens at about their head level - relatively speaking, their hips are much further away so they narrow. Disconcerting at first but terribly useful once you've gotten the hang of it. (Beware chicken legs or the reverse from dramatic perspectives.)

I read every review I could find before purchase, and this lens seemed to be a magic middle between the higher cost clarity of the 20mm and the cheaper lesser sharpness of the 28mm. Near as I can tell, I nailed it. The build and buzz create an ongoing sense of cheapness, but the performance really pays off if you need an affordable wider angle that generally won't let you down.

4.0 out of 5 stars Mr Watson, come here, I need to see you June 16, 2010

By Mr. A. Pomeroy

I was on the lookout for a good-quality autofocus wide angle lens for my Canon 5D MkII, and this seemed to be the best option. Canon's telephoto lenses are generally superb and they make some good zooms, but the company has traditionally had trouble with the wider focal lengths. I can't justify the expense of a 24-70mm f/2.8 or the 24mm f/1.4, and the 17-40mm and 16-35mm seem either underwhelming or too specialised for what they are. The 28-135mm didn't appeal to me, ditto the 20-35mm f/3.4-4.5, the 24-85mm didn't impress me when I owned a copy. The non-L wide primes include the 20mm f/2.8, which no-one seems to like; the 35mm f/2, which lots of people like but doesn't seem great in the full-frame corners; the 28mm f/2.8, which I have tried and hated, and the 28mm f/1.8, which doesn't appeal to me at all. The 24mm f/2.8 seemed to be the dark horse, based on the tests I have seen, and so I found one cheap and snapped it up.

It is surprisingly good. Not excellent, but sufficient. I already have a very good 24mm, an old Olympus 24mm f/2.8 that I use with an adapter, and although Canon's lens isn't quite as sharp it's more practical to use, on account of it having autofocus and an automatic aperture. I don't have to keep checking live view when I focus closer than infinity. I like the 24mm focal length, and with a 5D MkII I can always crop down to something approximating 35mm without too much loss of resolution.

Physically it's a solid unit that doesn't rotate or extend. It doesn't feel weak and I have subsequently thrust it into bags and taken it out and about without breaking it. The autofocus is buzzy but the focus travel is very short, so it's not a problem. The manual focus ring is dire and I have only used it when shooting video. Canon gives you front and rear caps but no hood, the meanies.

Optically it's close to very good. At f/8, f/11 it's sharp across the frame almost but not quite into the extreme corners, far better than the 28mm f/2.8 that I briefly owned. There is CA, but DPP will correct this. There is some barrel distortion, but it's not very noticeable and not offensive, and this is one thing the lens has over the 24-105mm f/4 (the other being that it's much smaller and lighter - in the end I went on holiday with this lens and a 50mm, and the combination was smaller and faster than the 24-105mm). Vignetting exists and is inescapable on a 5D MkII, this is the major optical weakness. At f/2.8 it remains sharp in the centre. The background blur is busy and it's not really a bokeh-licious lens. You, sir, are no 24mm f/1.4.

Drawbacks? The very extreme outer corners are always mushy but, having said that, outside the world of Carl Zeiss every wide angle lens seems to have this problem. On an APS-C camera it would be sharp but redundant, because your kit lens is probably just as sharp and also wider and it has image stabilisation. The other problem is the price, which is too high. If Canon reworked the lens, added USM, sharpened it up a bit more, they could justify this price, but I suspect they will simply discontinue it in favour of the 24mm f/1.4. Which is a shame, because it is otherwise a bit of a hidden gem.

4.0 out of 5 stars just what I expected June 6, 2006

By James P. Palazzolo

Amazon Verified Purchase

From all the reviews I read, I expected certain pros and cons from this lens. I was not disappointed.

pros: very sharp lens with very good colors

cons: vignetting at wide open, and a little too contrasty

For myself, the pros outweighed the cons for the price. It is ideal for the 1.6 multiplier cameras, where it becomes a 38mm lens.
