Originally posted by sormel I personally think the body doesn't really matter - you need to think about the lenses, and for those $100 I guess you can find something interesting.
Bottom line - if you like the feel of holding the camera - it's going to be something you'll carry along, which is when you'll use it to take pictures. Even trying - I can't think of a camera today that takes bad pictures - doesn't matter if it's five years old, what it boils down to is what's in front of the body (the lens) and what's behind it (you). :-)
I agree with your second statement, most bodies are definitely capable of taking great pictures. But in my opinion, the body DOES matter.
With the K-5, ii, iis I can do 95% of the changes and tweaks I need to do without menu diving. They have a dedicated AF button, which is decoupled from AE lock, which there is also a seperate button for. Dedicated button for ISO, and a dial for metering mode.
Those touches make, in my opinion, a much more enjoyable shooting experience, and can make the difference when conditions change fast.
In addition, the K-5ii focuses in lower light and has a quieter shutter.
it is just more refined and a more pro style body.
That is why I would choose the K-5ii.
