I can only realy offer a review of this extender on my EF 300mm F/4 IS.
The IQ is every so slightly less sharp but is is better than cropping the 300mm image.
Autofocus is retained on my 400D but it does take a little longer and its still quite acceptable. It almost lives on the lens now.
Of course you lose a F stop but you pays your money...
Recommended. Very glad I bought it.
Heres an example.

Overall very pleased with this extender. Currently i can only use it with my EF70-200 f/4. It drops a stop down to f/5.6 but it the lens is still very usable at this aperture.
I’ve found since purchase it tends to stay on my 70-200mm as I find the extra focal length better than losing it at the wider end. It compliments my existing 24-105 f/4 L IS as the wide end is 98mm. It should come in handy when I eventually purchase the 300mm f/4 L IS
Conclusion:
Superb accessory. No noticable loss of quality, a relatively low(ish) cost your get an extra .4 of a lens.
