Here's one from me.

...could be a marketing nightmare selling expensive zooms coming out at the same time (approx) with overlapping focal lengths..
Yeah, that makes sense. I'm sure VW and Chrysler are just as worried about the marketing nightmare of internal competition from their Porsche and Mercedes subsidiaries. Just like the 100-400 vs. 200-400, there's bound to be a lot of overlap in the customer base.
Off topic, but Mercedes never was a subsidiary of Chrysler. Daimler bought 92% of Chrysler's shares (I believe in 2003?) and then the company was named DaimlerChrysler, but they split in 2007. Daimler (and Mercedes as well as it is only a brand of Daimler) are now completely separated from Chrysler, just as they used to be before 2003.
Besides of that, I completely agree with your opinion.
Shot about 30 minutes before sunrise. Canon 5D Mark III and 24-70 2.8L II lens, on a tripod, using mirror lockup, a remote shutter release and 5-shot bracketed exposure. Initial tone mapping done with Photomatix Pro.
Pixel binning is a form of resizing, so yes If I took an 18 or 22mp still and resized it to 2 mp, I am pretty sure it would look better and crispier than if I paused a 1080p feed. Maybe I did not explain myself better before.There are a couple of reasons why a single frame from 1080p won't look as good as a 2mp still, and I'm pretty sure a lack of resolution doesn't come into it.
First of all, the video will be compressed very differently from a jpeg - its not just lossy compression of areas of the image, but between frames too. Secondly, when set optimally, the shutter speeds will be very different between the two. Typically with moving subjects, in a photo you'll want them free of motion blur - in a video, to avoid that stuttering effect, a slow shutter speed is needed (because of the slow frame rate) to allow motion to flow from one frame to the next.
The two really can't be compared, but if video ever gets to the point that NHK were on about - 120fps, higher shutter speeds on each individual frame will be optimal, further narrowing the difference between video and stills. However, current broadcast TV is 25 or 30 fps, so no optimally recorded 1080p broadcast TV will be able to freeze frame to create a still image as good as an optimally taken 2mp photo.
I just purchased this lens last week and can't believe how sharp it is! What a amazing lens! Here is a picture I took with it last weekend of a painted turtle in a wildlife refuge I was hiking in.
Oh my... If it as good as the 35mm 1.4, I could end up replacing all my primes with sigmas. Never in a million years would I imagine that.
What exactly is wrong with the autofocus at f/8?
A bit of optimal processing brings them even closer. For years the best sensors for noise per area were Canon P&S sensors, hard to believe I know, but if they had made a FF sensor using the P&S technology we'd have been using 200MP+ sensors with backlight performance for a while.
Who knows, I might sell my 100-400mmL
