Rated 5 out of 5 by from Canon 2X Extender III "If you are putting this on a high quality lens then it is a good way to get a lot of extra telephoto reach without taking up much room in your camera bag. Images when used with a great lens such as the Canon 70-200f2.8L IS II are very good and certainly a lot easier then carrying a 400mm lens as well. Of course with all extenders you loose a couple of stops - the 2X makes the fastest setting now f5.6 instead of f2.8. However with this long a telephoto reach the f5.6 will still give you pretty good background blurr. The extender fits perfectly onto the lens and camera body. Quality, well made product. Also well sealed. They also seem to hold their value when selling down the road at some point."

Rated 5 out of 5 by from Well worth the investment "Super telephotos are expensive and while excellent may not be the right investment for everyone. Putting a high quality teleconverter on a high quality lens can help you get the reach you need when you need it. I have used this converter with both the 70-200/2.8L and the 100-400/5.6L. Autofocus is preserved with the faster lens but lost with the slower lens. This has nothing to do with the teleconverter, but with the functionality of the autofocus modes in the cameras. It costs you two stops of light but you don't lose sharpness or contrast. The unit is lightweight and fits in a pocket. The III version of this converter is MUCH better than the II version that I had in the past. Contrast and edge sharpness easily justify the cost difference. If you've spent good money on L telephoto zooms or L telephoto primes, this converter is a smart investment for extra reach at a substantially lower cost of entry."

Rated 4 out of 5 by from "Light weight, double the reach..." "I honestly did not know that this would only work with telephoto - personal mistake. I was hoping when I got this it would also work with my 24-70 as well as my 70-200. However... am I glad I bought it - yes! I was able to sit in my back yard and get some nice shots of the chickadee's and gold finches in my back yard. A tripod would have helped, even a monopod as this makes it slightly heavier to use."

How well would this work on a 6d with a 150-600 Tamron Lens? (sorry, this is a whole new route for me, I'm a tad clueless)

Asked by: Heathercards
You would lose autofocus in the lens. When a teleconverter is added to a lens and the lowest minimum aperture (after conversion) becomes smaller than f/8, the camera struggles to focus. If you don't mind manually focusing, you would have the equivalent of a 300-1200 f/10-12.7 This reduced light will also require slower shutter speeds and increase the risk of motion blur.
