I have owned this lens for about 8 months now and it has quickly become one of the lenses I grab the most. I had a tamron 10-24mm EF-S lens that I liked but always felt was a bit soft. I sold it and bought this 17-40 knowing I'd eventually get my wide angle back when I bought a full frame camera.I use this lens on my 7D so the 1.6 FOVC makes it a 28-64mm equivalent. This is a very usable range and being an L series lens I knew it'd be nice. The red line lenses have yet to disappoint me. This lens is very sharp, and the color is very very nice. The great color was something I had not anticipated and is one of the reason's I keep grabbing it from my bag. The colors are vivid and pop with out having to push them in post processing.This lens is also a great value. Because it's only an f/4 zoom lens it's much cheaper than it's f/2.8 cousin. At this wide range I'm not finding the lost stop of light to be a big deficit (although I'm sure I'd love the f/2.8 equivalent). Also you'd be surprised how much nice bokeh you can get at f/4. It isn't like a prime that obliterates the back ground but you can still get a nice separation that pulls your subject forward. It's also nice that the lens is still sharp wide open so F/4 really is usable.It would be nice to have IS with this lens but it doesn't seem to hurt it too bad either since it's such a wide angle range. I'm really looking forward to putting this lens on a FF body as I miss shooting super wide and it seems this lens will do it very well. I expect I'll see a bit more vignetting and distortion but so far I really can't find fault with this lens, and to be able to get L series quality for around $700 new, you really can't complain. This lens does exactly what it's made to do and it does it very well. On my 7D it is my number 1 go to for a walk around lens. It covers the middle range focal lengths very well.

First off, if you're a pro with a bag full of $2000 lenses, you're probably not interested in this, the 2nd least expensive "L" lens.Secondly, if you're going to compare this to a bunch of $2000 lenses, you're barking up the wrong tree.My guess is the typical buyer of this lens is someone who is taking their first tentative step into the world of "expensive" glass. This lens is made to order for you. It simply blows "ordinary" lenses out of the water. If you're used to the kit lens that came with your camera, or a 3rd party lens you got for $150, you are going to love this lens. You'll find yourself taking more pictures, taking time to frame your shots and basically caring about what you shoot. This is a lens that is far more talented than you are, and you'll strive to rise to its level.I cannot say enough good things. The sharpness ROCKS. The saturation and contrast are absolutely fantastic. The focus is instantaneous and silent, and usually dead on. And the red stripe looks really cool! :)Its heavy, and built like a tank. If you're looking for a lightweight, this ain't it. It is lighter than most other "L" lenses, however, and not too bad to carry.Drop the 700 bucks, and go out and take some serious photographs.

Don't get me wrong, this item is expensive. It's worth it tho.! I was hesitant to hang over $1500 worth of camera/lens on my shoulder strap. After hiking in NM in various National/State Parks, I can say this was a life saver. It held strong and helped relieve pressure on my neck from a camera strap and on my hands. Highly recommend!

Does the job as expected. Priced well. You will need to buy a T Adapter as well if you want to attach it to your telescope. Don't forget to hit the lens release on your camera when you want to take it off! It's a simple thing to forget ...

It has taken me nearly 4 years to write this review but here it is. I have nothing but wonderful things to say about this DSLR Camera.Many wonderful memories have been captured through its lens. I am steal learning to improve my photos but this little guy has been perfect. I am sure I will be using this camera until it stops functioning.

The quality of housing not so good. Plastic around the lens already broken (I think that because of waterproof housing).Update 23/09/2022.I was offered new camera without even asking for one, so on base of aftersales service I changed my rating.As already written in manufacturer description this is not a professional camera and it cant compete with GoPro but it is also way cheaper so for the money it is a good buy.

my camera is like an extension of me. this body is awesome. Mine actually came with a 18/55mm lens, which was awesome considering I have a xs so now a friend and I can shoot at the same time. I really love creative auto mode. Im able to tweak settings but leave other settings up to the camera so Im not constantly fumbling around.

 Always take it with us when we go for a Motorcycle ride. Videos and pictures are good. I don't find the remote helpful. The camera times out after 5 mins. I use the app on my phone to control the video and camera.*Make sure your lens is clean..I had bug guts on mine all the time...lol*
