Quote: Canon appears to be faster and less accurate
; not true in my experience, it's just faster with USM lenses (but a fairly common myth on these fora). I have now shot a Ds, a K10, a K20, two 30D, two 5D and a 40D with a host of lenses, maybe I am just very lucky... maybe we can conclude that Pentax slow AF and Canon inaccurate one are both internet hype of some kind...
Quote: Pentax gets a lock in situations where Canon and Nikon both give up
; true in my experience, Pentax' AF detectivity is perhaps the best out there.
NR? Well, NR is NR and if you use it you loose details no matter what brand you use so better look at raws and if you do, you'll be hard pressed to find any differences in the most recent crops of APS-C cameras, the K20 being effectively up there with all the bests.
