Thanks Sandy, that's useful, especially the comparison shots. The FA* version is looking like the strongest 24mm (not surprisingly, I suppose) - heavier too. I'll look out for one, I think ...

Many thanks, as usual folks for some good and helpful feedback - much to think about ...
The K and A lens formula are the same I now realise, so I can look out for those, but as has been pointed out they may not be ideal for distant focus. In APS-C I rarely used the 15mm, preferring the 21mm for walkabout, but there were occasions where the small 15mm just did the job and this was what I was looking for in FF, ie a small 24mm at FF.
Having rarely used the 15mm on cropped I realise I don't have a natural eye for this focal length, though on analysis of past images I do see that I have sold quite a few from the wide end of my 16-50 which surprised me. I suppose it's the wide prime mindset that I'm probably not in, rather than just this focal length. A small lens at around 24mm on FF is my target that I can carry easily and train myself to 'see' with it, but not if it's not so good at distant shots. Yes I know, wide angles tend to need a strong foreground, but also the distance needs to be able to be properly distinguishable. The 15mm on cropped managed this well, albeit, the edges did die quite a bit, but at least they don't distort too badly, I feel.
Thinking about it, the *small* 15mm on cropped allowed me a good deal of freedom of movement, something I'm struggling with using the 24-70 on FF - it's just too bulky and awkward, and optically not what I was hoping for. Maybe I should look at the 28mm options instead ? They'll be some reasonable gain in field-of-view over my 35mm - not, perhaps what I was planning, but maybe this is a compromise, if the 28mm lenses are better optically and in size for me ... I need to take a look at them as well ...
Thanks again ...

Thanks Clackers, I did. It's a little large for me...

I'm very happily using the D-FA 50 and FA 35 primes on my K-1 and I'd like to extend the range wider, probably around 24mm. I can see on the lens search there are 4 x 24mm variants, what I'd appreciate knowing is the relative merits of each in comparison. I appreciate it's unlikely anyone has tried all 4 on the K-1, but what are your views on each, please ?
What I like about the 50 and 35 I have is their size and sharpness for landscapes, especially when cropped. Going wider to 24 mm, I appreciate the edges will depreciate compared with the 50 & 35, but I'd like it to be better than the D-FA 24-70. I'd prefer AF, but happy enough to focus manually if required. I shoot quite a lot into the sun so flare susceptibility is an issue, but again I can cope if this is a problem with the older lenses as compared with the new HD coatings that I've used.
Maybe 20mm might be OK, but 28mm will be too close to the 35mm
Possible availability is worth asking about. In the UK there's not many used like these lenses appearing very often, that I've seen. The possibility of importing from Japan is a complete unknown to me. From the USA may be easier, but I've not done this either.
Thoughts please ?
