It could be disastrous, so before you try it measure the trigger voltage of the flashgun.
You can do this with a meter, held across the flashgun contacts as you do a test fire.
We have measured some older guns at nearly 300V, which is far in excess of what modern DSLRs can handle. Under 10V should be fine.

But the idea of buying such a capable camera and nor doing at least some post-processing seems bizarre to me. It's like buying a Rolls-Royce and choosing to walk behind it.
OK, I'll get into the Rolls in future....But the idea of buying such a capable camera and nor doing at least some post-processing seems bizarre to me. It's like buying a Rolls-Royce and choosing to walk behind it.
But absolutely agree with that, although I could imagine a photographer who wanted the best quality or maybe to photograph something specifically needing an SLR, but who did not want to do any computer work.
It's just like an LX user having the pictures printed at Happy Snaps.

I'm not sure why you used such a wide aperture, but with little DOF to play with most of the images are out of focus.
The closer you are the more you need to stop down to get any DOF. Focusing needs to be very carefully done. If some of the image is to be defocused that's fine, but the composition should make it clear what the intent is.
A final, maybe contentious for some, point is that IMHO if no processing is to be done then I don't see the point of shooting RAW.

With all that computing power going into the design, if it needed an extra bit of glass it would be designed with one...Adding more glass to the optical path can only degrade the image, it can't improve it.If a lens already has thirteen bits of glass, for example, adding one more can't spoil it that much (if it's a good one).
With film there were other considerations and filters were needed. With digital it's totally different.

Not any old cloth - use a Pentax Microfibre cloth.

If you have dialled in +2EV exposure compensation then that is why it is over-exposed.
If you had left that alone the exposure would have been fine.
