Product Description
Manufacturer's Description
A new and affordable L-series ultra-wide-angle zoom lens that's ideal for both film and digital SLRs. Superior optics are assured by the use of three aspherical lens elements, in addition to a Super UD (Ultra-low Dispersion) glass element. Optical coatings are optimized for use with digital cameras.
This lens focuses as close as 11 inches (0.28 m), and offers both Canon's full-time manual focus and a powerful ring-type USM for fast and silent AF. It has a constant f/4 maximum aperture, and offers the choice of screw-in 77 mm filters or a holder in the rear of the lens for up to three gel filters. Finally, it offers weather-resistant construction similar to other high-end L-series lenses.

If you need a wide angle lens with superb build quality, weather resistance, great optics, superb colour and little distortion then buy this one.
I shoot a lot of landscapes, sometimes in harsh conditions like the English Lake district or French Alps, and need kit which will stand up to the abuse I give it. If I'm shooting landscapes then 99% of the time I reach for this lens, and if I'm climbing this is the only one I take. What more do I need to say?
I have also used this for group shots at weddings with great results (just ask the Bride!)
It's not light (but not really heavy as it's pretty simple with no IS), and not cheap by general standards (but cheap for an L series), but it does the job and does it very, very well.
I have noticed a little distortion at the very edges when close to the subject, but this is only to be expected at 17mm and for anyone with a crop sensor it probably won't be seen (I use a full-frame 5D). Other than that I have nothing but praise for this lens, and will get another (or it's direct replacement) if I ever kill or lose this one.

I cannot recommend this lens enough... for wide angle landscape and travel photography this lens is superb. I have used this lens for several years on a Canon 5D and previously a Canon 300D and Canon 300 film and have always found the results to be superb. For cropped sensor cameras this is going to be circa 28-70mm so pretty good as a general purpose lens and perhaps good for portrait photography.
It sits within Canon's f4 series of L series lens (and is thus half the price of its big brother 16-35 L lens)... for me given that it is most likely you will be using this lens for landscapes and thus want lots of depth of field I'm not sure the f2.8 premium is justified (even for portraits unless you are a serious professional f4 should be fine). The colour saturation seems that much deeper with this lens than the equivalent consumer lens (eg. 28-135), the build is solid (as would be expected of an L series lens) yet being wide angle and containing less glass this is not that much more expensive than Canon's prosumer range of lenses (eg. the 28-135).
For wildlife photography I find this to be a particularly complimentary lens to the big zoom lens (eg. a Sigma 50-500) so you only need to travel with two lenses. The weight is not too bad (it's the lightest L series lens) and the focussing is fast. There is no image stabiliser but at this focal length that's not an issue. Only thing to be wary of is putting filter systems on the front of the lens... it's 77mm at the front so be careful with eg. Cokin P filter systems as you may get vignetting on a full size sensor camera (not an issue for the cropped sensors as far as I know).

If you are reading this then you know that this is one of the most useful zoom L lens and probably one of the cheapest L quality lens out there. If you have a crop body (which I did start with) it is a truly remarkable walk-around lens which would occupy serious time on my 450D. Its that good!
It has plenty of uses. Landscape and street photography is where this baby truly shines (on a fullframe 5d mk ii) I would normally stop this down to f8-f11 (sweet spot) and just shoot away. It is sharp! You'd be surprised in terms of sharpness even comparing with few of my primes (85mm 1.2L mkii and 100mm 2.8L IS)
There are times I wished that this is slightly faster for indoor photography (a bit slow at f4 aperture) but then again it can do preety much everything else. Grab the flash and problems solved.
The focusing speed is blindingly fast. Accurate without need for micro adjustment. Built like a tank and can take few serious knocks. Mine has! Phew! It is something I can't say about the 85mm 1.2L ii which would give me palpitations everytime it gets some time on the 5D (amazing lens though).
Its a great beginner lens too especially if you are like me, start small and then get sucked in into the world of photography. In no time at all you'll have a FF (full frame) with few quality L lenses. Not to mention down by few thousands euros! Ouch!
Enjoy snapping and don't tell me I didn't warn you.

canon 17-40 f4 L Lens
A really useful wide angle lens, which gives very crisp images across its focal length.It's fairly hefty, but then this is because of the superb build quality of Canon L Lenses.

Brilliant
This is a great lens. Very happy with it. I have it on my 500d at all times - it is great with the crop. On this camera it feels very balanced and a good size and weight ratio. Read more
