10 out of 10 points and recommendedAffordable, Beautiful boken, Quality build.low light preformance
Love this lens, no comparsion to the 18-55kit lens from the Canon 30D. Sharpness right out to 100%, which we all want and deserve. Beautiful boken, love the 3D affect from this lens.reviewed November 29th, 2006 (purchased for $800)
I would recommend a tripod or atleast a monopod to fully take advantage of it's capabilty. Most all poor shots come from camera shake, put this baby on a tripod with mirror lock up or timer and you will immediately see the difference.
I put the 1.4Canon extender on and could not notice any degradation of picture quality, sending a squirrel shot from this set up to a contest. This speaks for itself as to my recommendation of this fine lens.
