Originally posted by Winder If street were my interest I would go with a Fuji X-E1 and the 14mm or 35mm.
For small street gear, I have the Olympus E-PL3 with the Pansonic 20 / 1.7 and Olympus 45 / 1.8. (Got those because the Pentax K-r has a loud shutter and no tilt screen.) Plus, I have some nice small film street photog rangefinders, like the Canonet QL17 or Ricoh 500G. The rangefinders fit in a jacket pocket and have surprisingly good glass. So I think I have the small street camera covered. For now, at least.
This is really about a DSLR replacement. I like Pentax for street also because the DSLR is smaller than those from Canon and Nikon and the primes are great. (Ltds, and legacy).
No question I am getting some version of the K-5, just depends which of the 3.
