ens performance doesn't depend on the amount of light well, that's something new to me )

@MichaelClark Ziess doesn't have AF, otherwise we wouldn't have this discussion and I've already bought Zeiss 35mm f/1.4. What I meant is that Zeiss lens did let much more light through. Canon 85mm f/1.2 is definitely brighter than the Zeiss f/2 though

it's a shame though. because according to this test: facebook.com/… the bokeh on canon can get REALLY ugly (

well, i'm going to be using it at f/1.4 a lot. no point in buying a f/1.4 lens to use it at f/2. And the deal breaker for me is that it appears to eat less light than the canon as I feared (this is extremely important to me)

well, it's about time, and for 50mm f/1.2 too.

well, this looks interesting: amazon.com/review/R90LRWO9H0HO8/… On the copies I have, the sigma offers no increase in sharpness or image quality when compared to the canon, a substantial step or two down in terms of vignetting, and requires approximately 1/3 of a stop slower shutter speed to expose the photo equivalently to the canon. Looks like a deal breaker for me ((

hehe. as canon proved by producing plasticky version of 24-70 which costs twice as much )

also, what worries me is that I don't understand why Sigma is nearly twice as cheap as Canon. It's not Canon, that's $200 discount. Where are the other $300?

The oft rumored EF 35 f/1.4L II is being talked about again. We’re told an announcement for the new “L” prime will only happen once the new EF 24-70 f/2.8L II begun shipping in decent quantity. That would put the announcement sometime in 2012 with availability probably being in early 2013. One patent for the optical forumla has been around for a while. The rumor has come and gone many times already
