35 L II and the 50 f1.8 IS
Could also be update of 135L, but 35L is in more need IMO.
+1 again These 35 and 50 mm lenses are direly needed to upgrade Canon's lens line-up.
I'm in agreement here. These are both holes that need quick plugging, particularly considering that the Sigma is ending up in a lot of bags, and, for others of us, the new 35mm f/2 IS is actually in many ways superior to the current 35L. It is my most recent addition.
Count me in for wanting the new 50mm. I don't have an AF 50mm in my kit right now because I was never blown away by the (non L) 50mm choices. I have owned and then sold two copies each of the 50mm f/1.8 and 1.4. I have never bought the 50L because of both its own shortcomings and high price. I make do with some vintage options (Takumar and Helios), and really enjoy those lenses. But for a lot of work AF is really needed.
