6 out of 10 points and recommendedvery good results in good outdoor lighting; one gets fast AF, strong color, and sharpness from this lens in daylight in the magic hoursnot very good outside its optimal conditions, it cannot compete with superior glass. I agree with the reviewer all the way. If you use it in the conditions for which it was designed one can get very nice images. Outside that window, put it away.
I just echo the first reviewer's assessment - good travel lens for casual work. I use mine for railroad photography in daylight and get plenty of nice results. It's useful window is limited due to the limited maximum aperture and less satifactory images at extremely small apertures. I think you would get a bit more out of it with a 20D whereby you can use higher ISO settings with lower noise compared to 300D that I currently use.reviewed October 20th, 2005 (purchased for $155)
