On a final note, Is it me or do DSLRs need a lot more attention paid to the AF compared to film? I really can't recall having these issues with my old MZ-3, although I didn't shoot much moving wildlife just due to the cost of the film!
What size did you regularly print when using film ? With large MP sensors now we are able to examine the capture in much higher detail than was usually the case with film.

My comments above on the accuracy and speed of Af on the K1 was related to AF-S and generally static subjects. For sports/wildlife it is fair to say Pentax has been lacking when tracking a subject. The newer lenses are better....my DFA 70-200 tracks much better than the older DA* 60-250 for example. I would keep an eye on the latest model however, Pentax must be well aware it is one area they get criticised for and I would expect the K- "new" to address the issue.

I have never used them for scanning, but I get all my prints from these people....... https://dscolourlabs.co.uk/about/Scanning_Services

Very high quality on the print work they have done for me (24x16 inch).

I use K1 and paired with a modern D-FA lens is a very fast accurate autofocus. It is also fast and accurate with 20 year old screwdrive lens. Just needs to be calibrated properly.

Suggest you wait for the new aps-c model to be released, expected this year, but you should expect to get the latest lenses to get the best performance both optically and for AF speed.

I missed this too. The second one is for me. Here the condensation has created it's own soft focus effect on the outside.

Yes lovely light on all three.

Number 5 grabs me here. Patterns, lines, and tone. Great stuff.

I don't think that Alan has retired, he fixed a lens for me last Thursday.
Good to know. He knows my manual lenses better than I do.

So now to the question. How can I tell whether colours that are not quite matched are out of sRGB gamut, so cannot be matched by tweaking, or within gamut, so could in principle be tweaked to match?
I agree with John and Rob. Especially with 600 paintings to work on !

However one thing you can do if you find an awkward mismatch is to do a proof gamut warning. I only know Photoshop, not your software I am afraid.

In Photoshop I would process the raw file in a wide colour space like AdobeRGB or ProPhoto. Then open the image. Using the soft proofing tools select the "device to simulate" as sRGB. If there is an option to "preserve RGB numbers" make sure it is unchecked. Then select "Gamut warning". Any colours that are not capable of being displayed in sRGB will be highlighted.

The problem here however is that unless you have a wide gamut monitor to view the image on while working on it, you wont know if the wider colour space image renders the picture any more accurately than in sRGB ! If you have a significant mismatch you will be just as well to try and eyeball the colour to the closest match rather than delve into the dark arts of wide gamut editing.

One final thing is that although you profile your monitor to get accurate sRGB display colours, I doubt your family do, so what they will end up seeing is anyone's guess
