I use the Ona Brixton and it will fit that combination quite comfortably. I have the dark leather version and it's a fantastic bag although a bit expensive.

Here´s a short video, where he is demonstrating the fantastic (in his view) autofocus with facial recognition on the D4S:
Even for a totally still, well (over)lit face, it still hunts ...
In his D4S review, which he claim has the best AF system in the world, he is using his kid on a swing, as "the ultimate AF challenge"
He must have picked an excellent copy of the original 100-400 for his comparison. I'd say my version 1 lens is average but the version II lens is excellent. My copy of the new one is much sharper wide open plus the much improved IS and twist zoom is a "must upgrade" if you use this lens a lot.
They tested four copies of each generation 100-400, and averaged the numbers.
One thing I'll just throw out for discussion regarding 100-400 comparisons. It's a lens we find we have to optically adjust fairly frequently over time (maybe 10% of copies) and the problems are always at 400mm only. The 4 copies I tested had all been optically tested and screened on a bench prior to this measurement.
I was skeptical that this lens could live up to the hype. It appears the hype was justified:Roger at Lens rentals disagrees. He just posted a comparison of the old and new 100-400mm and there isn't that much difference between them.
He also posted on the 400 DO. Which appears to be significantly better than the mark 1.
Hopefully Roger will get some Sigma 150-600mm's soon and run a comparison between them,the Tamron and the Canon 100-400mm II
I was a bit surprised at the 100-400 results myself, I expected more difference. Shooting test charts (same ones as TDP uses) I could see a difference that the Imatest results didn't measure. Perhaps it's a decrease in some aberrations? I'm not sure.
Sir, I do not think, that Conon will release an "bad-sensored" camerabody. Maybe the IQ is not the the IQ you get from the Nikon D800E or Sony A7 36MP. I hope - it will be on an equal level like the IQ of todays Canon products.
Just think of, what will happen to Canon if this Camera is rubbish? They will never release an under-average product.
Maybe it took so long to developa an good high MP sensor.
Wasn't that what the EOS-M was considered to be by many... even Canon themselves(recently)?
EOS-M was only under-average on AF ...and corporate support of the basic idea. The IQ is actually quite good and I think APS-C is not a terrible call to split the difference between the mirrorless world that wants everything made smaller and the mirrorless world that wants best possible IQ. They clearly need products for both camps, but APS-C is not a terrible starting point and the EOS-M could have been successful as a result.
But I still don't think Canon has launched a mirrorless system until they give us a @#$%ing EVF and more than two native lenses to choose from at B&H. The embarrassment of the EOS-M is not the product so much as Canon pushing a ship in flames out of port with a vague intention to 'put that fire out soon'.
The 5DIII will be 3 years old in March next year. A move to 50MP will pretty much follow Moor´s law. That same law should indicate just over a doubling of its computing power and given the speed of new memory cards, we should a least expect a camera that could chew 50MP at a slightly higher speed than the 5DIII and thus see at least 6, probably 8 fps.
It's great to know who makes generic plates, but who else does decent lens-specific replacement feet with integrated ArcaSwiss rails? Being lighter, more compact, and directly attached to the collar could be great.
Low light performance is just happens to be the most important video feature, it is the one feature that can get you the shot or miss it. The GH4 is basically useless for video past ISO 1600, and not that great at 1600 either. The 5D3 gives great results up to about ISO 10,000 and with Magic Lantern you get zebras, peaking, magic zoom, and a ton of other goodies, so the GH4 doesn't cut it for me. The Sony A7s will be a great option when they get a good selection of native FF lenses, but Canon will probably have an offering before Sony gets the lenses made.
I suppose this happens to all manufacturers nowadays.
(to summarize, there is a light leak when shooting into backlit scenes using live view)
Looks like they were determined to copy the 5DIII as closely as possible.
Up to now I have used 14mm, 21mm and 16-35mm (and once in the past 300mm f/4). The nice thing with this mount is that I can trust it with a heavy setup since the attachment is at its center and it has no need of counterweights.
I would not trust a 500mm lens even on the new device you mentioned mainly because I would fear the excess size would make it prone to accidents...
