Sorry, I'm rather new here, I do have a lot of Pentax equipment and I like Pentax very much. I asked " Can you do this with a K30, K50, K5 or K3 ? " referring to the difference of DOF that exists between APS-C and FF. Since K30,K50,K5,K3 are all APS-C, I don't think they can render like a full frame. Here we are talking about FF upgrade path.
But honestly, shall Pentax forum be a religion, you have to tell me if we have to deny technical differences between different format or types of lenses or cameras.
Also in the case that Pentax forum is a religion, I don't understand why there are reviews of sigma lenses on this forum, they should be banned because Sigma are taking sales away from Pentax.
I have a friend from Canon who behave like this: for him, Canon is the best and all the rest is shit. I don't want to be like him, I want to be an open minded photographer.
Please clarify what should be said and not said on Pentax forum, I'll respect the policy.
