Kinda curious, how many of you would buy a new 50mm 1.4 with fantastic optics? That's the kind of lens I have been waiting/hoping for. Even if it was let's say $500, I would still jump on it. Am I the only one who doesn't have thousands of dollars and would still love to have a great affordable lens like that?
Ahhhh.. I had a good chuckle at something you wrote above, michi

"Even if it was let's say $500".
It's much more likely to be closer to $1000 seeing the price of most of Canon's latest offerings! Eg the 24mm f2.8 USM IS and 28mm f2.8 USM IS are around $800. A much faster (eg f1.4!) lens, even without IS would cost around $800 to $1000 is my guess.
I'd be happy with a new 50mm f1.8 that has true (ring) USM (IS could be a bonus) for around $500-$600, or a f1.4 for around $800-$1000 with true USM (IS again, just as a bonus). I had the 50mm f1.8, but sold it - as the focus accuracy & speed as well as bokeh aren't up to my standards.
I want a fast lens (at least f2), around 50 - 60mm, very high IQ wide open, true USM. That is the only real 'gap' in my current lens range

I have 4 other lenses: 10-20mm, 15-85mm, 100mm macro and 70-300mm L, so the 'fast quality prime' is the one I'm looking for.
I've seen too many focus issues with the Sigma 50mm f1.4 to be convinced by it. Same (weak, not true full ring USM) with the Canon 50mm f1.4, where many copies are not sharp enough wide open either.
Please please please Canon...
