I thought I'd try the MKII's auto focus with the extender. I will say that it was a little slower but not by alot. I did have some ok light as I shot this at ISO400 F10 - 1/1000. It only required the normal sharping after re-sizing and over all I was very pleased with the IQ, Plus it was nice to shoot at 560 :D
Thanks for looking

Great shot. Wonder how it performs with the 2X?

Not well in my experience. You need a LOT of light, since it starts at f/11. And, even a 1d can't auto-focus(maybe with taped pins?). There are folks here that have posted some very good results with a 2x on a 1-4, but I don't find many opportunities to use such a limited configuration.

MDoc: Very nice detail on this shot. Looks like your 1-4 works better than mine with a 1.4x. Mine gets a bit soft, so I never use it that way.

You've nailed the focus for the given ambient light. I have struggled many of my shots with my 2.0x TC (sorry for being on a different subject). If the light situation is somewhat close to perfect, then my TC has saved the days, in my opions off course! Great capture Ray!

Very nice pic of an osprey, a species that has had twenty years of dedicated work to bring back to the UK, but it's still rare here.

Thank you Sindri. I just had my MKII professionaly cleaned and adjusted because I was worried about the auto focus being soft. So this test proved to me that my camera is spot on :)

Great shot! I have tried a 2x TC on my 100-400, but not for a while, and it was on my 30D so I had to manually focus, so no wildlife ventures with it.

I've had some success with the 2x on a 300, but at this moment I'm really trying to squeeze the most from my 300 alone with a new 1D. I like the 2.8 added focus ability, but I'll play with the TCs again, soon...

Great shot Ray, I have been thinking about getting the 1.4X converter and wondered how it would function with my 20D.
AF would probably be a nightmare and to loose an f/stop would be a pain. I want the great Bokeh that I have seen with the 500mm f/4 but I just can't afford that kind of money for a lens.
Oh well.
On another subject has anyone used the 100-400 with Kenko extension tubes?
Would love to know what the limitations are to this set-up. I would love to be able to focus closer.
