If they release a 70-130 f/2 so many portrait photographers will either buy it or sales vate over it (if they're not Canon shooters, or don't have the budget). That will be an amazing lens.50 1.2 and 28-70 F2 definitely are stunner. They already patented 70-130 F2. I wouldn't be surprised they are working on 14-28 as well. I just hope they come out with 105 1.4 too.
