9 out of 10 points and recommendedGreat image quality wide open, wonderful bokehSlow to focus, large minimum focus distance
A very useful lens for portraits. Best for female portraits, especially on women with large, but non-dominating hairstyles.reviewed January 5th, 2010 (purchased for $1,600)
Also very good for night photography, if the subject is not moving quickly.
Surprisingly useful for indoor sports where the subject has predictable motion, for example, gymnastics.
The AF is much slower than on the 70-200 f/2.8 IS, though, making this lens less useful for fast-moving sports, such as basketball.
Finally, while the DOF is great for video work on a 5D MK2, the lack of IS coupled with a relatively long focal length make for jittery images.
