Danny Green Talks the Canon EF 100-400 f/4.5-5.6L IS II

I found it strange that at the bottom of page two, the asterisk about the 1.4 extender ..

* AF with Extender is only possible with EOS-1 series cameras, EOS 7D Mark II and EOS 5D Mark III (with firmware update).

That for such a new body, the 7DmkII would need a firmware update already .... surely they would have matched them already to work ...

I read it as only the 5DIII needed a firmware update, and they could simply be referring to the changes made in the 1.2.1 update that enabled AF at f/8 for the center point.

Sure, it's a advert, with all the attendant hyperbole and the occasional error (as pointed out above), but the image gallery is impressive ... virtually all shot at 400 f/5.6; i.e., wide open at the long end of the zoom range. Too bad they didn't see fit to enable clicking on the images to open them at full resolution.

Yeah, seems they were all at f5.6 and mostly at 1/250. On the one hand, its impressive to be able to get relatively sharp shots (as far as we can tell) wide open. On the other hand, f5.6 would have been imperative to maintain an acceptable shutter speed (marginal at 1/250 @400mm handheld you would think) and an iso below 1,000. Bearing in mind not everyone has the luxury of a 1DX.

We can only assume that these were shot handheld. We may be induced to think so by the shot of Mr. Green holding his camera to his eye with this lens mounted, but that doesn't necessarily make it so.
