In the 24mm fast lens category:
  • The Canon EF 24mm 1.4L MkII is as good as a lens can get, hands down.
  • The MkI of this lens isalmost as good, and,it can be sometimes found used
  • The Canon EF 24mm 2.8 is often criticised for softness and slow AF,it is not an USM lens
  • TheSigma 24mm 1.8 is sometimes disliked for poor corner sharpness and vignetting onfull frame bodies. No HSM here, either.
  • Neither Tamron nor Tokina make a fast 24mm lens.



I know that becauserecently I too was interested in buying a 24mm prime and decidedto wait and collect some $ (I should say $$$$) for the L MkII
