7 out of 10 points and not recommendedLight weight, modest size, great build, look&feel.Way too costly for only reasonable optics.
I have used this lens for 8 months on a Canon 350D.reviewed February 19th, 2006 (purchased for $1,100)
The comments in this site's test are dead on for this lens. And that's a shame, because the look&feel of this lens are ideal for my small 350D. I really have to work hard to get a sharp image, and the results can be inconsistent. If I avoid shooting wide open, keep the ISO low, the shutter speed above 160, and shoot longer than 16mm, I can ALMOST depend on getting a good, sharp useable image. Even better if I fire up the Speedlite. But you cannot push the optics on this lens at all and stil expect quality.
