It is hard to improve upon a product when the product is among the finest lenses in the Canon EF line, but it has been done by Canon with their new EF 70-200mm f/2.8L IS II USM Telephoto Lens. It consists of all that is great of the original plus it improves on the optical quality, functionality and speed. The sharpness is pretty incredible especially for those who never had an L lens.
If you are indoors, the photo will be sharper because of Image Stabilization. Motion blur via the movement of the lens will be reduced, but not from the subject, where greater effect comes from the bigger aperture. To protect the camera from the elements, there’s a black o-ring at the mount but to make a complete seal, you’ll need a lens filter. It works nicely with portrait photography or sports. Many may think that there’s no reason to upgrade from an already good lens. September of 2001 is when the original zoom lens became available, so there’s well over 9 years of technological advancement for you to benefit from in the new and improved second edition.
There’s a much better design to the buttons, and transitioning to MF when shooting isn’t a problem any longer. Unlike the first edition, there’s no sound of the gyro as the new edition has the silent Image Stabilization technology. The optics are actually improved for better quality, with one fluorite and five UD elements. There is now diminished flare in the improved contrast. Focusing is noticeably quieter and quicker and closer so you can take tighter portraits. With the different texture and a lock feature, it makes it easy to put on and take off the lens. If you are intending on keeping it for years, it is really worth the upgrade.
Canon has always created fantastic lenses and you pay a lot for the privilege of having one. L lenses are quite heavy because in order to keep a fixed aperture of f2.8 for the whole zoom range, lots of glass is needed. A few tips which will help you, include using Mode 2 of Image Stabilization if you are intending on panning right or left, like following a car. If you choose 2.5 to infinity on the focus distance selector you could have difficulty focusing indoors.
If you look at the reviews, you will see most of the shoppers gave the Canon EF 70-200mm f/2.8L II IS USM Telephoto Zoom Lens for Canon SLR Cameras the highest recommendation, which is pretty good for something so pricey. The lens is rather expensive so you should only buy this if you are a devoted hobbyist or a pro.
