Customer Reviews

Canon telephoto zoom lens is great.
Though it can take some time to learn to use it, it has been very helpful in taking pictures that can't be taken with a normal point and shoot.

Good allrounder
This lens have the qualitys I need for allround use, fits easily into my backpack, or just mounted on my camera it's not to heavy. It has a fast and prescise autofucus. Mounted on a good tripod it takes excellent pictures with little noise, and crystal clare imagery.

A good deal both in quality and price.

Excellent lens for medium telephoto
This Japanese made lens is compact, light weight and well made. I use it in combination with a Canon IS 28-135mm lens and a 50mm prime lens. These lens cover most of my photo needs. Focusing is fast and accurate with the ring type USM auto-focus. Ring type USM focusing allows fine adjustment to the focus without switching to manual focus mode. This is not the case on the USM motor focus found on the lower cost 75-300mm Canon lens.

My lens stays quite sharp to the eye at full zoom. The lens is effectively a 160-480mm with the 1.6 cropping factor of my Canon 30D.

AS the lens does not have image stablization, it is best used with a tripod in lower light. Perhaps some of the softness reported by others at 300mm is actually the result of camera shake which is hard to avoid at full zoom.

Finally in my view the build quality of the Canon 100-300mm lens is superior to the lower cost 75-300mm USM lens. The Canon EF70-200 f/4 L is sharper but far more expense.
