The k-30 seemed to come and go from the market somewhat quickly. Although i like the body styling of the k-30, which is why i chose the k-30 over the k-50,
HOWEVER,,i can't shake the the feeling that
the k-50 may be a more refined camera as far as software and hardware
. That is to say Ricoh, possibly taking what they learned from the k-30 and applying it in the k-50.
If i had it all to do over i think i would try to get a k-5IIs new.
This is where i got my new k-30. Not the cheapest price , but it was actually new.
