For my purposes a K-3 already kicks the D800, A7rs behinds, if you took this same picture with a D800 or A7r, you'd have to use a 600mm lens instead of a 400, and the subject would still be smaller, because of the k-3s smaller pixels and and therefore more magnification. Now if what you're saying is you don't value what a K-3 brings to the table that's fine, but why would you come into a K-3 images thread to tell us you don't value what a K-3 has to offer, and claim you need cameras that don't match it at what it does best. It's like coming into an apples thread and saying you want oranges. The ones who are here for the apples. don't really care about Pentax making an orange.
You guys need to be posting in a more appropriate thread.... seriously. When a D800 or A7r can match this, I'll consider them. But why would I pay thousands more, for an inferior image?
