Any recent rumblings about the 35mm f/2?
Seems to have been out of stock for a while locally and online at most of the major retailers.
No rumblings at all. IMO, Canon is unlikely to update any EF non-L primes, except perhaps the 50mm f/1.8 II (to reduce production costs, as they did with the EF-S 18-55mm IS and 55-250mm IS lenses, which together with the 50/1.8 II are the three top-selling lenses for Canon).
FWIW, the 35mm f/2 is frequently out of stock (probably a limited production lens), and it's been that way for several years.
