ef17-40_4l_1_

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 (0.28m), 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 77mm 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.

Pros: Price (in comparison with 16-35mm L it's a steal! And the quality isn't bad at all), sharp (even wide open), very fast and accurate focussing, decent zoom range, very good build quality!
Cons:
None really, just that you need a filter to complete the weather sealing (this isn't really a negative)

Where do I begin?

I bought this lens to replace my old walkaround lens (28-105mm f3.5-4.5 II USM). That lens was quite sharp, but not wide enough for my 40D. Then I looked for a wide angle lens. The 18-55mm lenses just didn't attract me... too cheap and nasty, so I tried out a 16-35mm and this lens and after weighing the positives and negatives of each lens I came to the conclusion that the 17-40L was the lens for me.

It is indeed very sharp, from f4! I only stop it down to f9-11 for architectural/street/landscape photographs as my copy is very sharp from f4.

I recommend this lens for someone who doesn't want to bust the wallet and for anyone who wants a wide angle lens with L series build quality. This lens is very well built and the focussing is very fast and upto now it is also very accurate.

What else can I say? At its price it's a no brainer against the 16-35L for me. Yes the 16-35L is a good lens but for me it didn't go far enough at the telephoto end and the image quality didn't seem too superior (on the one I had used anyway).

Just buy it!

Pros: Absolute perfect for touring especially if you will be mixing landscape situations with indoor situations.
Cons:
A little distortion on the outer edge (hard to see unless you are looking for it)

Just completed a two week trip in Europe. Visited Rome, Monaco, Lisbon, Barcelona, Paris and London. I bought this lens because I was worried about having a walking around lens that I would not have to change out every minute. I also knew that I would be visiting several historical sights that I wanted to be able to get a shot of the outside of the building and most of inside of the building. This lens was an absolute LIFE SAVER ! Used this lens with my 40D.

Pros: Light n small, build, optical quality
Cons:
Not really, a bit soft in extreme FF corners.

I use it on 1DsII, and it is a damn good lense ! It is small and light but build like an L !
Contrast and colors are just amazing.
Sharpness at f/4 is very good in center, with corners softs.
At f/8, extreme corners (really extreme !!) stay a bit soft, but overall sharpness is just outstanding, it resolve really thin details everywhere ! A bit of distortion but hey, it is 17mm on FF !

I prefered 17-40L to 16-35II due to 77mm filter alone (I don't need f/2.8 at such focal leghts). Definitely a keeper, specially at that price !

Pros: Good build, tack sharp if you use it properly and understand how to use a wide angle
Cons:
Price, I think the lens is slightly over priced

When I first bought this lens I was using it incorrectly. My expectations for a lens in this price range were very high. My first images were disapointing and what I thought I was buying was the answer to all my image woes. The mistake that I was making was that I scrutinizing detail at 100% image size...couldn't see the forest for the trees.

I use it for all types of photography, it's a great lens

Pros: very good for garden/landscape
Cons:
not so good for isolated subjects

bought off of Craigslist for $500, it is excellent for what I use it for: pictures of the garden to keep a record of how it is doing with most shots at 20-30mm both at around f/8 or above (usually at hyperfocal focus) on a tripod and some at f/4 handheld, color is fine as is the "IQ", pics could be a bit sharper
overall the 17-40 does what I got it for.... have shot some of isolated subjects (flowers, kids..) but the 50mm 1.4 is much better than this is at 40mm for these kinds of pics
had tried out the 16-35 L and while it is a bit better the optical difference, for my purposes, didn't justify the price difference
the consensus review of the 17-40 seems to be that it is a lot of value for the money and I concur with that

Pros: Best L for the price. Sharp, light wt., compact and the lens doesn't extent when zooming.
Cons:
Hood. I'll have to switch to EW-83J.

For the price of $500, I have no complaint. The only thing I wish Canon to fix is switch out the current hood, otherwise I have to spend $50 for a EW-83J hood. Some may ask for IS, but is it necessary? It's a wide angle, and I don't want to pay more for something I don't use.

Pros: sharp...light...build...great pricing...
Cons:
silly hood

unbeatable sharpness, color and price....i also have the 24-70 L 2.8 and this is half the weight...trust me the 24-70 is just as sharp and renders colors great, but holding it steady w/out IS requires a fast shutter speed due to the heaviness of the lens, not only for a blur free shot but also, its not a walk around lens thats comfortable...

Pros: Sharp, tough, flare resistance, great range, red ring :P!
Cons:
None

Great lens for both full-frame and crop-sensor cameras. It is durable, not too heavy, but well-built. The sharpness blows me away...It is very sharp. This lens will stay in my kit even when I get my 5DmkII or 1Ds!

Pros: build quality, constant aperture, very good optics
Cons:
Chromatic aberrations wide open

I own mine for a couple of weeks replacing a tamron 17-50 f/2.8.
Impressions till now:
- excellent build quality, smooth focus and zoom ring though I like more the ones on 70-200
- USM - fast and reliable focus
- f/4 is slow for interiors (look for a faster lens)
- light around 500g, easy to carry
- the hood is ugly but that's not a problem
- on 400D at the same aperture ( f/4 ) is sharp as the tamron in the center and much sharper in the corners
- exhibits chromatic aberrations wide open even in the center of the frame stopping down helps eliminating them (are gone by f/5.6)
- comparing both lenses at f/11 I noticed much better contrast and sharpness from canon (lower degradation caused by diffraction)
- the tamron at 17mm is a little wider than the canon

hope this helps

Pros: Sharp, fast, light weight.
Cons:
Horrible hood.

I first used this lens on my 30D as a walk around, but never quite went wide enough, or far enough. I tried Sigma 18-50 f2.8 which was great but still lost out on the wide end and focus hunt was awful. I finally upgraded to a 5D with a 24-105L - my dream combination since it came out a few years ago, but finally at a price I could reach. But what a weight, and distortion at 24mm very noticeable if not careful with positioning. Then the 17-40L when on and wow, full frame is what this lens was really made for. In combination with my 70-200L, is is everything I have always wanted. OK - it could go just a tad longer, and to f2.8, but then it would be a whopper again, and with the image quality of the 5D, cropping to the equivalent of around 80mm is a piece of cake.

Pros: Quality, weight, price, ideal range for landscape on full frame.
Cons:
None.

I use this lens on a 5D and it is far better than my 24-105 in terms of image quality. The colours pop, the images are crisp, the skies are awesome. I didn't do any sharpness test, but it is plenty sharp for me (printing up to A3). I use it a lot on a tripod, closed down from F8 to F22.

The range is really great for landscape on a full frame camera, from super wide to almost normal. Coupled with a 70-200 I have all I need when I know I can spend time on setting up my tripod, change lens, etc.

It is truely a joy to use with a 5D, and if you are using a tripod and good technique you can quite easily obtain great, great, great results from this lens. Be carefull with polarizers, don't use them at full strength at 17mm otherwise you'll get strange looking skies!

On a 1.6 camera I think there are much better alternatives (17-55 2.8 for instance, or the Tamron alternative). 17 is not that wide on these cameras, and 40 feels short compared to 55, so in my opinion it does not qualify as a good walk around lens on these bodies.

The equivalent of this lens on a 1.6 camera is a 10-22 or 12-24.

It was really designed for full frame.

Pros: This lens is superb, its very very sharp, with great colours, contrast and it makes the sky look 3D. Its better than the 10-20mm and 24-105mm and produces better colours and contrast than the excellent 85mm F1.8. Fantastic. Anthony www.hopesphotos.co.uk
Cons:
None

Pros: good wide to normal zoom range for a crop boddy, great quality (build and optically)
Cons:
supplied lens hood is a bit much on a crop body and does shadow the onboard flash

I've seen a few other reviews that praise this lens as a good choice for the 40D and I can only concur. If you need something faster, this isn't it, but I love it for landscapes and as a general purpose zoom on the crop body.

I originally picked this lens as a compromise, concerned that it wouldn't be wide enough on the 40D, but not wanting to get heavily invested in lenses that would not cover full frame. So far, I've been more than pleased and feel no need to go wider for what I shoot - at least for now.
