why are (almost) all my canon primes so old?

Why we need new primes for the new focus system !
In reply to Blastophaga, Feb 9, 2013

Just have a look at focus stories on lens rentals.

Beginning with some of the lenses announced 2010, Canon seems to have introduced a new focusing system that works with 5DIII and 1DX. Basically the focus quality in traditionnal shooting becomes equivalent with live view focusing, except for the speed. 

I find that the focus with 135 f2 could be slightly more consistent. In my opinion there is some plus minus 1-2 cm variation. Obviously that is pretty good, and I am always surprised by the number of keepers, BUT this means quite a number of pictures could be somewhat better.
