EF 70-200mm f/4L USM
7345

Overview
High-performance, L-series telephoto zoom lens combining light weight and compactness with an f/4 maximum aperture. Inner focusing and the ring USM enable quick and quiet autofocusing. Also, a circular polarizing filter can be attached and used without difficulty because the front lens element does not rotate during focusing. The tripod collar (sold separately) is the same one used with the EF 300mm f/4L USM.

Great for outdoors
This lens works great outdoors in normal light. The pictures are fantastic and the sharpness is nothing short of amazing. No need to think twice unless you need low light capabilities then go for the 2.8 version.

Outstanding overall zoom lense
This lens has the versatility to shoot close semi-macro and also utilize for great sports photography (and everything in between, e.g. portraits). I place it on a monopod lots and it makes it easy to move and change settings. Very pleased with the performance and picture quality.

Get this lens!
This is my first L series lens and I now understand what the fuss is all about regarding the L series lenses. I've had this lens for 2 years now and I couldn't be happier. Super sharp images, great color, and great contrast. I mainly use this lens for portrait work. While it needs a bit more light than its 2.8 brother, it is still a great lens.
The lens weighs a little bit and I recommend using it with a tripod.
Great workhorse lens!
Try the L series lenses. You'll be glad you did and you will see a huge difference in your photos.

Perfect
Incredible image quality and it's a very light lens. If you're doing landscapes, this is the lens for you. If you want to do sports/high action shots, then go for the more expensive f/2.8L lens only because it's got a larger aperture.
