When I first tested this against the Mk2 extender for IQ with static indoor test subjects, I thought I had made a mistake in spending so much in that the differences in IQ other than in the mid / corners did not seem that different.

The Digital Picture

The Canon EF 2x III Extender mounts between your Canon EOS Digital SLR and a compatible lens (primarily Canon L Series lenses), extending the focal length of the lens by a very noticeable 2x.

Imaging Resource

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.

I was very impressed by this extender having tried a lesser quality one. Works very well with the Canon 70-200l is USM lens.

If you have the Canon 70-200mm f2.8, this is the ideal addition to your bag. This saves you buying a 400mm lens. Its workers perfectly and the picture quality is fantastic. If you want to save some money and have the versatility of having a 70-200 and a 140-400mm lens then it a recommended purchase.

Brilliant item I was about to purchase a 100-400mm Lens to compliment my 70-200mm Clad I went for the cheaper option Works a treat Right through out the range I will of course in maybe a Year or so go for the larger lens but for now I can't think of any reason to do so

WEX

I wanted this 2x extender for use with my Canon L series Lens. It is easy to mount to the lens and onto the camera. The only downside is the extra weight but you can't have everything.

I bought this specifically to use with my 70-200L f2.8 IS USM II lens, and I've been very pleased with the results. I was already using the 1.4III extender with that lens, and wanted the 2x to give me yet more versatility without adding too much weight.

WEX

Saves spending a huge amount on another lens if you don't absolutely have to.
