The Pros:Full frame. Lightweight - the lightest L series lens to date. L series - Canon's highest quality glass, professional build and optics.
The Cons:Weaker fixed aperture of F/4, not as good as the professional F/2.8 standard that allows for better performance in low light, better DOF seperation. No image stabilization.

Three Aspherical lens elements and a Super Ultra-low Dispersion glass element combine to provide high quality images, and a optical coatings have been applied to aid when the lens is used with digital cameras. The lens can focus as close as 11 inches, and uses a fast and silent autofocus in addition to a ring-type manual focus. Filters can be screwed into the 77mm fitting, or up to three gel filters can be placed in a holder in the rear. The construction is weather-resistant to allow the lens to be used in a maximum number of settings.
