I recently bought the EF 1.4x III to use with my 70-200 F/4L IS and they work great together, however, I tried it with my EF 100-400 L and was not overly impressed. I tried the live view magnified in to get the best focus possible and it still was not all that great. I took a lot of test shots of ducks and a couple were ok. I was even shooting at 1/1250, 1/1600 and 1/2000 and at the f8-f13 range.

Has anyone else tried the EF 100-400 L with the EF 1.4x III with any luck?

Thanks

Hi chadpope,

The 5D2 will struggle to AF with the 100-400mm lens plus a 1.4x extender (source). Even if the focus is perfect any extender will typically exacerbate optical issues with a lens. But that's just the theory and as I haven't any experience with that combination I'll pass the baton over to others who might...

Bob.
