Some patents were released/filled, but it's hard to guess if something like new 50 f/1.4 will be released. If you need that focal length then I would suggest to go for Sigma 50 f/1.4 - it's a decent lens and yes it is usable on 1.4 and I think that it has better bokeh.
+1 for the sigma
Real usm, (in my opinion) better bokeh & great IQ at f2.0 and wider. Those are my top 3 reasons for chosing the sigma...
I'm also waiting for any news…
I'm buying a new 50mm lens within the next 3 or 4 months (baby coming soon).
50mm is my favourite portrait focal length on my 7D. I also have the great 85mm f/1.8 but I don't use as much as I use my 50mm f/1.8.
I'm pondering between the 50L f/1.2 and Sigma 50mm f/1.4. But since 50mm is my favourite focal length, I'm thinking of getting the best possible and go for the L (not that I need the 1.2..it would be nice to have it, but I would stop it down a little bit...I'm considering the Canon for it's sharpness, color, contrast, built quality, etc).
I'm not so concerned about the price tag here…
How does the Sigma compare with the 50L?
