just bought K5 myself. had to do a check with the helpful information here as i did not know you could check the manufacture date. mine is May 2011 and a 4053XXXX serial so am hoping that i dont have any QC issues. did think it odd that it still had v 1.01 firmware on it but maybe they dont put latest firmware on before it leaves the factory.

having come from 35mm Canon A1 through EOS 300 then LX3 compact i am looking forward to having fun with this bad boy.
