Canon EF2XIII extender EF2XIII review

We reviewed the Canon 400mm ƒ/5.6L USM back in 2008, which makes a good candidate for comparison with the 200mm ƒ/2.8L USM and 2x Extender attached. In terms of sharpness, the two are quite similar: the 400mm is slightly better at ƒ/5.6 and ƒ/16, but at ƒ/8 and ƒ/11, they're almost identical.

Love this extender.

I love this extender. Its a bit expensive, probably Canon Extender EF 2X II is most logical to get. I did not own previous extender so I cannot compare them. This is my first extender, works like a charm, love it.
