It should be obvious - this extender really needs to be used with a tripod. That alone will increase your image quality. It's also designed for the higher quality Canon lenses - the EF series. 90% of the complaints about this accessory ignore those two facts. The next biggest complaint - autofocus. Again, Canon is clear that you need a lens with an aperture of 2.8 or faster in order for autofocus to work. Basically, so what! If I'm on a tripod shooting my subject, I'm going to pre-focus . The depth of field is in such a compact area and you're zoomed in so much, autofocus is really not that important. What did people do before autofocus? Skip the photo?
So if you understand what you are purchasing and know how to use it - well, like with any great tool - you'll produce fantastic results. If you don't know how to use it, try and do a hand-held 400mm zoom, or attempt to catch that bird as it swoops past, forget it. This is not a $5,000 lens. It's a $300 add on that extends your current lens.
If you could afford that 10 lb, 800mm telephoto lens - at $12,000 - you would not be looking at this accessory. I'm not trading in my car for a lens any time soon - and this little accessory does the job just fine. I've tried it on action shots freehand - even though I knew better. Forget it. Handheld when it's added on to my 200mm? Almost as bad. On a tripod? Fantastic. Even better if you have the remote trigger.
The bottom line is that if you are looking for an affordable alternative, know how to use it, and are willing to spend the half hour it takes to master this multiplier, you will get great results. If you expect to point and shoot, then buy a point and shoot camera.
