8 out of 10 points and recommendedSurprisingly sharp at the long end, great contrast and color.I need more time with the lens....haven't found any negatives yet.
This is my 4th L Series lens and I am as pleased with this one as any I've purchased previously. Images are amazingly sharp at both extreme ends of the lens and wide open apertures. I'm still getting used to the mechanics of the lens, but I am amazed at the IS capabilities, sharpness of images, contrast and color. The lens provides reach that is beyond my L Series 70-200MM, but it is every bit as sharp.......and that's saying something.reviewed March 10th, 2012 (purchased for $1,430)
9 out of 10 points and recommendedVersatility, tack sharp images, color & contrast, build quality.Some say weight is an issue...I have not found it objectionable.
The most used lens in my arsenal. This lens stays on my 40D most of the time. It is a great walk around lens and provides tons of flexibility when touring. I find that the image quality is superb and f2.8 speed allows for easy low light shooting. It's my Go-To lens and I've used it more than any other lens in the bag.reviewed March 10th, 2012 (purchased for $1,150)
9 out of 10 points and recommendedL Series Image and build qualityLow light limitations of f4 lens.
I use this lens primarily for landscape and architectural photography. It is light weight compared to most other L Series lens, but the image quality is heavy duty. Low light shooting may be limited because it's an f4 lens, but it is sharp and capable of great color capture and contrast. It is very much an L Series lens.reviewed March 10th, 2012 (purchased for $750)
