Summary: Best money I ever spent on a lens. I purchased this lens new in 1994, and have used it on most any subject you can think of, except for macro. I have shot low light, long exposure, portraits, landscapes, and most everything else.
Summary: From day one it never worked correctly and then the lens would not sink with my Canon MKII camera - sent the lens to Canon and they can't fix it because they no longer make the part - this purchase was a total loss and I had such great expectations.
Summary: I wasn't expecting much for a 10X zoom, but this lens handily beats all of the consumer and mid-grade zooms in my experience (on a 5D mark II). I'm normally not a huge fan of push pull zooms, but it would probably be very hard to accurately and quickly twist between 35 and 350mm.
Knowing What It Does Well (and doesn't) Is Important!!!

Summary: It's very old, but looks and feels new, and I only paid $700. I've taken thousands of photos with it in a few months because it stays on my Canon 7D most of the time for landscape photography.
Summary: Had this lens for years and it is fantastic. Works great for action shots or for casual use. Delivers some really high quality images and with a range from 35-350mm can cover more than most lenses. At 1/2 the price of the 28-300mm it is a great option that is worthy of consideration.
Summary: this is the best lens i have ever used!!!! it is fast and the clarity is great.... have shot with other lenes.. and none compare.... best investment you can buy in my opinion./// spend the extra dollars and get a hood....
Summary: I feel this to be one of the most useful lenses ever built by Canon. Worthy of the Luxury (L) label it bears, the image and build quality are both excellent. This "Super Zoom" is so titled for its ability to be a "one lens fits all" solution.
