I have used this lens which came with my camera for 10 years. It has had little use and was well looked after. Provided good results. The zoom was a bit of a problem when looking up or down as it would start to slide, so has to be held to avoid booking in or out. Until it goes wrong!.....

Used this lens for several years, replaced it with Tamron 18-270, not as sharp. During my time with the 17-85, I enjoyed its sharpness and light weight. However, midway through, it lost its autofocus and I had to have a repair by Canon, not cheap.

In my condition of amateur, i use to buy second hand items to try to save some money, and in most cases those items work very good. But in this case, this lens has a focus problem that doesn't permit to work fine. Nevertheless the lens is very good

I bought this lens when I upgraded from 50D to a 7D mark ii. The ability of the 7D mark ii to store in camera lens correction profiles is a game changer for lenses like this. It may not be a perfect lens, no lens is, but now you have the ability to fix it in camera without having to play around in...

Really great zoom range; Good image stabilization

Not as good as my 17-40; but hey what do you want for the price

I've owned this lens for 10 years, having purchased it shortly after buying my 20D back in 2005. The lens has always performed perfectly for me - never a hiccup of any sort. To be fair, the lens does not produce "L-series" quality, but then, it's not an "L-series" lens.

Bonne lentille et très pratique pour toute occasion

This lens is somewhat of a mixed bag. Optically, it's a great step up from the kit lens, and a reasonable compromise on price vs. performance. The image stabilisation is great, if not quite as great as the marketing material might suggest.

There seems to be a lot of quality control issues with this lens. The main problen i have with this lens is "zoom creep". Its also hard to focus manually. Other than that, the lens is good. I traded the kit lens that came with the camera for this lens, and i'm glad i did.

good lens if you dodge a lemon

Poor build quality; zoom creep

I have had this lens for around 4 years now & have taken at least 8,000 photos with it. Compact, fairly light weight, & easy to use makes it an ideal walk around lens for shooting close to medium range subjects.

Easy to use; Compact

I just bought this lens and tried it over a 2 day period, shooting scenery and macro shots at the Botanic Garden. The greatest thing about this lens is you don't need to change lenses for different shots. I took wide angle shots, flower shots, macro shots of bees.

Focuses very close; Very close focusing; Fast / accurate auto-focus

Poor in Low Light
