How disappointing! I expected the Canon 1.4x extender would fit my Canon 30D with Tamron 18-200 lens which I have used with 2 Canon cameras but alas the mount for the lens has a part sticking out so that the Tamron which fits on Canon camera won’t fit on Canon extender lens. It seems it will only fit with a Canon fixed focal length lens. Would be nice if the ad makes that clear before ordering.

Something I really wanted, to extend the range of my Canon 70-300mm lens for use in zoo photos, nature, etc. Well, it fit the camera body just fine, but would not fit ANY of my Canon lenses that I had for my (former) Digital Rebel or my (new) 30D. What? So what Canon cameras does it fit? So I had to send it back. I even double checked the ‘compatibility’ of the extender from previous reviews on Amazon, and double checked them against Canon’s own site. My lenses included the ‘standard’ 17-58mm, 10-22mm, 100mm Macro, and 70-300mm Zoom. NONE of these lenses would attach to the front of the 1.4 extender. Why was the front of the extender so small, that none of these lenses would connect? Someone made a big mistake in the list of lenses that don’t fit. Does it work with L Glass only?

I purchased this at a photographic store because a professional said you shouldn’t go higher than 1.4x. Just keep in mind–1.4x is only “40% better”. It worked really well, but didn’t increase the zoomage enough. I decided to go with a 2x (that’s twice the zoomage) teleconverter by kenko instead. I gave this one to my brother-in-law for Christmas.
You have to think about what you want–I want to get in really close to the birds. I have a 70-300mm zoom lens and 1.4x takes it to 98-420mm. It is an improvement, but not nearly enough! If you want to get twice as close, this isn’t going to do it for you. If you want to get half-again-as close, this almost gets you there.
As far as quality, the quality is definitely there. Five stars for quality, 3 for insufficient zoomage.

Good product. I knew already (obvious) it would turn my 70-200 f/4 into a 98-280 f/5.6, but I was not sure what the effects would really be when I bought it.
The product is well constructed and have very good optics. I would definitively recommend.
The only reason I dont give 5 start is because I think Canon should improve documentation on their website, explaining better the effects of the extender (reducing speed in 1 f-stop).
