100-400m L with a 1.4 x MKII converter?

Hi,
Does any have or use this combination? If so are you please with it? how much does it affect the final image ? I'm thinking of buying the converter but haven't seen any images taken with it on the 100- 400 mm so would be grateful for any feedback..

I have this configuration and it so somewhat useful but not ideal. You loose autofocus so all focusing is manual or what I use is live view. Also, you need a rocking tripod or very high shutter speeds because any little movement looks like the earth is frying apart, but that just a drawback of zooming in a whole bunch.. The IQ is ok but nothing stunning.

We have a thread here that shows different lens/TC combinations, and there are few 100-400 shots in there.

It won't AF on anything other than 1-series bodies.
IQ will be affected, but IMO still usable.

I have 1 series body so will it auto focus? Thinking of wildlfe so auto focus would be VERY useful LOL.

Yes it'll AF on the 1D series. You'll only be able to use the center AF point though.

That's cool as i prefer to use that anyway most of the time...thanks for info... might have to "treat" myself to one LOL
