Query: Sharp Pictures & Video with the Canon EF 70-200 F/2.8L

I recently added this great piece of glass to my lenses as an Indie Filmmaker. The images are fantastic. Video and pictures are extremely sharp with excellent bokeh.This lens is a bit heavy; however well worth it's weight when it comes to having an F/2.8L. I struggled with the decision between the F/4L and this F/2.8L. Hands down, I made the right decision. Night shots are beautiful in low light situations. I would caution against using this heavy lens without a tripod; as every shot counts.This lens comes highly recommended for shooting with the Canon 5D Mark II. This isn't a good carry around lens; however provides excellent pictures and video at long range (70-200mm). It is difficult to compare other non L lens from Canon - as this is a great piece of quality glass. The lens is built like a tank!
