8 out of 10 points and recommendedIS, USM, Good focal length, Not too pricey.Widest is f/4, Image quality.
Sold this lens after 3 months. Going to buy a lens that offers f2.8 instead since I take mostly low light photography. The range is good and it is a great walk-around lens, but I find that the IQ is not that great.reviewed July 31st, 2008 (purchased for $340)
The AF is great. I've compared this to the EF 28-135 IS USM which focused slowly than this EF 17-85. Tried focusing on a close object then focusing on a distance object. The difference was obvious. This lens AF much faster.
I haven't experienced any zoom creep, even when I intendedly tried to. Carried this lens on a hiking trip and there was no zoom creep what-so-ever.
Some people complain that this lens is heavy. I thought so at first but after attaching a grip to my XT, it balances out nicely.
Good lens if you don't take handheld pictures in low light and this makes a great walk-around lens.
10 out of 10 points and recommendedVery sharp, quick focus even in very low indoor lighting, white colored, pro quality, zoom does not extend.Large lens hood, minor difference between 135mm and 200mm range.
After reading much reviews about Canon's quality control is lacking and buyers eventually returning their new purchase for calibration, I bought this one used.reviewed September 13th, 2008 (purchased for $500)
I tested this lens in really low indoor lighting and the focus is amazing. Never thought this lens was able to focus at a specific spot where I was aiming at. This was attached to my 30D. The image quality is superb. Even though this lens has a max of f/4, I was able to get really sharp images hand held under indoor lighting.
I don't think the white color is a con, like other users think, because it does appear to give the impression that it is a pro quality build. I do think that the lens hood is ridiculously large and takes up too much space in my bag.
If I get the money, I'll spring for the 70-200L F2.8 IS. But in the meantime, this lens will definitely meet my expectations. At $500-$600 retail, I think it's a steal.
For those who don't need the 2.8 or IS or don't have the money, get this one instead. This is one satisfying lens for sure.
