Will Canon ever release a 100-300 f/2.8 zoom? Thoughts?

[J.R.]

Saw the Sigma thread http://www.canonrumors.com/forum/index.php?topic=14801.0 and couldn't help but wonder what will it take for Canon to come up with its own 100-300 f/2.8 zoom.

Do you think such a lens will be released by Canon? If yes what would it be priced at?

A 140-285/2.8 is pretty much a mythical 200-400/4 with a wider AoV and a 1.4x telecompressor built in. Use that as the basis of the price and availability, should Canon come to the conclusion that there is a market for such a lens.

With the 70-200 II and 300 II and most pros having two bodies, I'd have thought there's not much call for such a lens. Especially bearing in mind what the zoom would be likely to cost.

It would probably be more expensive and heavier than the current 300mm f2.8 L IS II...so is there a point in bringing such a lens to the market? Especially considering the failings of the Sigma 120-300 OS, it would need to be a true 300mm at the long end and keep that focal lenght through the focus range, a true f2.8 and have stellar AF and IQ. It would be bigger and heavier that the prime....so why not take a 70-200 f2.8 on one cam and the prime on another? It's not too difficult and a lot of press pros already do that.
A classic pro line up is either a 16-35/24-70/70-200 line up or a 24-70/70-200/300 line up. Each with a cam fitted, ready to shoot.
