Yes DNG and PEF are the same quality.

How is the size between them, are the DNG of the K-X compressed as well so roughly the same size as the PEF?

Do you've a photo with a bit more colour?
It would also be great if there is something white and grey in the shot

We just solved one and another colour problem pop up

It could be the colour profile that's wrong or maybe the white balance.
I don't have your program so you need to find those settings yourself.
If that didn't do a thing then clearly something else is wrong.

Pef files don't have generation but they are simply camera specific so they differ per camera model.

Here is mine version.
Almost the same what Prieni have done but instead of a graduated grey filter I use a colour burn layer that only effect the lighter tones so the clouds.
Then I also added a colour dodge and a but before all that I make the photo b&w and coloured it again.

You too Patrick

I was thinking about the Pantone book but that's very expensive, but I came across the cards in a photoshop.
They cost €23,95 so that's reasonable.
I'm sure there are other brands as well.

Here is the Dutch shop that sells them, just in case you can't find them in the UK link

Flash sync is only influenced by the shutter cutains.
It could be that sony calibrated it very critical to get the higher sync numbers, probably they took the number on which they knew the curtains aren't infront of the sensor.
Because the SR move the sensor it needs to have a bit more room so a less critical number must be chosen.
I think Pentax took the less critical one and took the time the shutter is open fully, so no relative to sensor size or placement so SR does not influence the sync speed.

I'm not a photocamera engineer but it does make for a logical explanation.

ps. in my previous post I was talking about the K7 explicitly, sorry that I wasn't clear about that.

Yes, you're but no SR doesn't have influence on flash sync.

I'm with the others here.
The hdr does some nice things with the colours and contrast here but you can probably do that with some good playing with the curves.

Also because of the tone-mapping you have a glow around the mountain around the middle of the frame on both side of the valley.
It's in the highlight points and I find it a bit distracting.

Nice photos Jack
I like how you place the focus in the bee shot, that photo looks very sharp.
