Reviews:| Rating 4.5/5 from 160 reviews | | Fabulous Travel Lens | | Rating: 5/5 (1 out of 1 think this is helpful) 2010-07-13 | I purchased this lens as my primary landscape lens on a 1.3 crop body, but since I've owned it, I've found tons of great uses for it. I use it often as a great upper body and fully body portrait lens. I have recently used this lens as a travel lens while traveling through Spain, and on a 1.6 crop body, this makes a perfect traveling lens. It's lightweight. The front element doesn't extend during zooming or focusing. It's wide enough to capture whole street scenes or buildings. The color saturation is just wonderful. It's sharp as a tack especially stopped down to f/8 or so. Even wide open, the lens is decently sharp and crisp. I have been incredibly impressed with the quality of this lens since day one. I love that it's so light and easy to pack up and carry with me all day long. The lens hood fits nicely and is easy to store and remove. Barrel distorion is minimal even at 17mm on a 1.6 crop body. On larger sensor cameras, however, barrel distorion is much more noticeable but this can be corrected for in post processing fairly easily.
I debated between this lens and the 16-35mm f/2.8 II for quite some time, but decided for budgetary reasons to go with the 17-40, and I have not been at all disappointed with my decision. I've yet to be in a situation where I needed f/2.8 on this lens, although for some, this would be more important.
I highly recommend this lens to anyone needing a good wide angle. | | Amazing on a 40D | | Rating: 5/5 2010-06-29 | What an amazing lens, this works perfectly as my walk around lens. I know it is not the most versatile zoom lens but it does everything i need it too do, and it does it well. If i need a longer range then i will pop on a 70-200 or if i need something to handle low light i will switch over to a Prime lens, that way i do not sacrifice quality.
A zoom is a zoom and they are built to be handy they are built to be easy, they are not built to be the sharpest lens ever or to handle low light situations. If you need a lens like that then buy one that is built for that purpose like a Prime lens. If you want a lens that can handle multiple focal lengths, if you want a lens that wont break the bank and you don't need that extra stop for something specific then you want this lens because its everything you need to have fun.
Not to mention it looks awesome on the front of my 40D.
Positives:
*Great quality
*Versatile
*Solid
*I do not need a lens that handles every focal length like a 12-500mm super duper whatever, i need a lens that handles wide to medium and this is the one.
Negative:
*Only thing i can really think of is that the lens hood is a little too bulky, i like the hood and i use it all the time. The new coating on the inside to reduce glare is great, but it just takes up to much room so i need to pack it separately.
| | A True Luxury Lens | | Rating: 4/5 (2 out of 2 think this is helpful) 2010-04-13 | I bought this lens as a replacement for my EFS 18-50 kit lens.
For APS-C SLRs there are plenty of options in this focal range (EFS 18-50, EFS 18-50IS, EFS 17-85IS, EFS 17-55IS, EFS 15-85IS, Tamron 17-50, Tamron 17-50 VC, Tokina 16-50, Sigma 18-50 ....... ). I was not originally considering this lens and was leaning towards the EFS 17-85IS or Tamron 17-50 (the EFS 15-85IS and Tamron 17-50 VC did not exist at the time). However after trying it at a store, I just had to have one!
It has a certain feel to it that is indescribable. Its a pleasure to use. Mounted on my Rebel Xti, it is well balanced. It feels substantial but not overly heavy (less than my EF 70-300IS). It balances the camera well when a flash is mounted in the hotshoe (which can be an issue with lighter lenses). Its very solid. Resting on my hand its very easy to manually focus with my thumb and forefinger; and zoom with my pinky (or thumb), without shaking the camera. Both zoom and focus rings are very smooth. Auto-focusing is so fast and silent, that I often wonder if it actually focused!
It focuses quite close. Its a good close up lens for objects that are as small as a child's hand.
Image quality seems fine to me. I can't say its any better or worse than my EF 70-300IS which I have no complaints about. I do think the colors are better on the EF 17-40 (but that could be my imagination).
I do not find the focal range limiting, but this is not an all-in one zoom! Its a wide to normal. If you need more telephoto you will need to carry another lens (like the excellent 70-300IS or 70-200 F4). If you want an all in one lens go with something else. You have lots of choices!
The constant F4 aperture is great for general purpose outdoor/daytime use. Indoors or at night you will typically need a flash, to keep the shutter speed up high enough.
For its focal range I do not find a lack of image stabilization an issue. Daytime outdoors I can hold the camera steady enough, and indoors I use a flash.
I would recommend this lens to anyone looking for a general purpose wide to normal zoom on an APS-C DSLR.
| | Great lens for the money | | Rating: 5/5 2010-03-28 | I would have bought the Canon 15-35mm f2.8 lens, but I haven't won the lottery yet.
For the price and the fact that f4 is just one stop above f2.8, I'm pleased.
Just a bit of a warning for people purchasing a Canon lens, and you probably already know this, but some Canon cameras will take both the EF series lenses and the EFs series lenses. However; some Canon cameras only use the Canon EF series lenses and not the EFs series.
| | Not for beginners, a slow lens | | Rating: 3/5 (1 out of 8 think this is helpful) 2010-03-22 | Admittedly, I'm a relative beginner to this level of equipment. I'm used to my lenses having image stabilization (IS). This lens does not. Many of my hand-held night shots were blurry due to a combination of camera shake and slow shutter speeds (its a relatively slow f/4 lens).
I ended up returning the lens for the 24-105 f/4 USM with IS. Amazing difference in picture quality.
I'm sure the pros can get outstanding image quality from either lens, especially with a tripod at night. But I need IS for my typical shots, which are hand-held, in poor light. The IS gives me about 3 full stops equivalent advantage regarding hand-shake. (nothing for subjective movement of course)
So, my recommendation; try this lens in your most difficult anticipated situation before you buy it. Or, buy from a place you can exchange. |
