A new Supertelephoto Zoom?
This is definitely a lens that Tamron would make. If you need length and you’re on a budget, this could be a one of a kind option if and when it comes to market.

They’re out there
We’ve been told by a couple of places, that the new EF 600 f/4L IS II is out there. Loaner copies of the lens have been sent to various manufacturers of accessories for measurement and that sort of thing. Multiple reports say they are fully functional production versions of the lens.
Lots of initial praise for the lens, especially how light it feels in comparison to the first IS version.
A very good sign indeed.
Canon Mirrorless Fun
A patent showing an 18-45 f/3.5-5.6 kit lens for an APS-C sensored mirrorless camera has appeared. That would be a 29mm-70mm lens when crop is factored in.
Are we getting a goodie before Christmas?
Received an email today saying Canon may announce a new lens on or around December 6, 2011.
This could just be in retaliation of the suspected Nikon announcements on November 30, 2011. No mention of what lens, which lowers the possibility in my eyes.
I can only think of one time a lens was announced and I had heard absolutely nothing about it, and that was the 55-250 II.
