I've read it works ok if you don't mind loosing a couple of stops.

I had a Canon 1.4 before and now use a kenko Pro 1.4X. I tested them both heavily on a 300 f2.8L IS and a 70-200 f2.8L. My conclusion was both were equally sharp with a slight edge in color going to the Canon. I kept the Kenko because it doesn't have the protruding rear element like the Canon and thus will work on pretty much any lens. You will love either on the 70-200 f4L IS as that lens takes a TC as well as the 300 did (meaning it stays extremely sharp with fast AF.)

BTW as Walt mentioned you lose 1 stop with a 1.4X and 2 stops with a 2X but the 70-200 will still AF fine on any of the Canon bodies as it becomes a 280mm f5.6 with the 1.4X on. what's interesting is that stacking 2 1.4's seem to work better then a single 2X on that lens as well (but if you need that kind of reach all the time you might as well get a 400mm.)

I rented the 2x once and didn't like it at all... maybe I just had a bad one. I need to put the 1.4x on my list of items to get though. Shooting from shore to boat, I need just a little more than my 200mm gives me.

The only lenses the 2X's work really well on are the Canon super teles 300 and up, unbelievably well actually.

My Kenko 2X wipes out the color/sharpness on all my lenses, I only use it in a pinch. A quality 1.4X is a good investment.

The canon 1.4x is awesome. I'd buy it without hesitation if I needed the extra reach.
