New 100-400mm 4-5.6L on CanonRumors.com

He says he got the details from what is usually a solid source. What interested me most, and what turned me off to the current 100-400 when I ultimately decided on the 400 f/5.6 is that this one is rumored to have a ring zoom as opposed to the push/pull. This article was published shortly after showing details to Canon's latest patent (nov 5th) for this lens.

"Finally on its way?I was told today that a new EF 100-400 f/4-5.6L IS will be making its debut “soonish”. It will be after the EF 200-400 f/4L IS 1.4x is officially announced.
It could be tested at Euro 2012 before being announced.
Features

• Ring zoom (not push/pull)
• Latest IS System
• 82mm Filter Size
• Weather Sealed
• Slightly heavier than the current model
• Slightly faster f/4 at 100mm (Current is f/4.5)
• Retail around $2800 USD

CR’s Take
A few folks want an EF 400 f/5.6L IS, I’d think this sort of product would fill the void. I’d expect it to be optically awesome.
This comes from a pretty solid source, though lenses are always hard to nail down.

Now I'm finally interested in the 100-400. We'll see how the Bryan shows the sharpness compared to the 400 f/5.6L on the long end though.

I actually like the push-pull design - it's very fast to use. But, I would not mind a ring zoom as long as it's an extending design (like the 70-300 L, for example). If it's an internal zoom like the 70-200mm series, it will have to be longer than the current 400mm f/5.6L, and IMO, one of the big advantages of the current 100-400mm is the (relatively) compact size when retracted.

I also like the push pull design a surprising amount. I thought I would hate it, but I prefer it at times.

weather sealing and better IS are the features that jump out at me for a new 100-400.

but for double the price it better have much better IQ too

What! CR think the togs at Euro 2012 are going to be using 100-400 f5.6, Im sorry but I don't think so. Every football tog I know who shoot the UK Leagues including the Premiership ALL use f2.8 either 300 of 400 mm, I'd take everything CR say with a very large pinch of salt.

CR’s Take
A few folks want an EF 400 f/5.6L IS, I’d think this sort of product would fill the void.

And the current lens does not fill the same void ???????
