The 200mm lens sounds fine but I doubt it is any better in terms of sharpness than the 50mm and even if it is I am sure the difference is minimal .
You stated that you want the ultimate macro lens. Look no further.

However, you'll only find the 200s second-hand now, and expect to pay over UKP 1000.

I'm going to take a stab in the dark and say eventually?
not a shortening I have seen before but would make sense given the price of the 1.2
Did you know that Westfalen (where Linus lives) has the same root, etymologically speaking, as the word "film"?
Nor did I.

And I wouldn't choose the 40mm. No point on digital.
The 35mm is a reasonable alternative to the 31mm if size and price are considerations, and the 50mm is a nice portrait lens and optically superb.

Are they therefore automatically culpable
But they're still liable to pay.

But, it won't meter very well.
And, you really can't focus quickly enough on wild birds with a manual focus lens. AF is pretty much obligatory, so that cuts out older lenses with exposure complications.
If, despite that, you do buy a K or M lens, then you can use it at full aperture in AE mode, and the camera will set the correct shutter speed. I do that all the time with my old 400mm.

A star lens (eg: SMC Pentax-F* 1:4.5 300mm) is, indeed, a star. With price to match.
Even more stellar are the Limited lenses (eg SMC Pentax-FA 1:1.8 77mm Limited). The original FA versions are best; the more modern ones are very compact, and relatively slow. Pentax should have given them a different designation, but they are still very well made and very good.

"I just want the ultimate 1:1 macro lens"
Later you contradicted yourself and said you wanted more than 1:1.
It's difficult to give advice in situations like this.
