Sigma 100-300mm f/4.0 APO EX DG (mark 2 version) which performs very well with the matched, 1.4X APO DG teleconverter. These do come up in PKA mount from time-to-time, but tend to sell quickly. I've had one from new and it'll probably be interred with me
Tamron 70-200mm F2.8 Di LD Macro - far easier to find than the above and can be had in excellent condition, even from dealerships and with a warranty (my copy came from Ffordes) for under £300.00. Don't believe everything you read about the AF performance of the Tamron. Whilst not whippet-like, neither is it sloth-like. Sharpness and contrast increase dramatically above f/2.8. Has excellent close-focus capability. See also link
Happy hunting

The Pentax DA 55-300 old version performs remarkably well on the K1, is readily available, relatively inexpensive, lightweight and compact for travelling. Yes it's still APCS an you do get a bit of vignetting but nothing so serious that can't be lived with or rectified in post.
If max aperture is really criitcal to you then maybe the Sigma 100-300 as has been suggested but even that only has a max aperture of F4, is not cheap and somwhat heavy. F2.8 limits one very much to a 70-200. For a good alround general purpose though I still reckon the Da green band 55-300 is a good option to consider.
Just a thought.

Hi Peter, I'm not looking for something as large, heavy and expensive as this. I have a DA*300, which I love and will never sell, also a 1.4 TC, so this is my go-to wildlife setup. The 150-450 is definitely not what I'm looking for.
Kind Regards

Thanks Defragged, I have owned several 55-300 lenses and this is not one I would consider, I want one that has no compromises on full frame, i.e. no vignetting. I prefer my 80-320 to the 55-300.

DA* 60-250 is worth a shout if found cheap enough. Once the baffle is removed it's near perfect in FF mode.

You don't really need AF - assuming your subjects are not moving. There are dozens of top quality vintage offerings out there going for peanuts.

I second the Sigma 100-300. Super lens. Got rid of mine as at 2010 I was going the other way thinking Pentax wouldn't go FF and sold my Sigma 70-200 and 100-300 to get the DA*60-250. The longest focal length I have now, since I only have film and K-1, is 200 mm (D-FA* 70-200).

I have a Sigma 100-300mm f/4.0 APO EX DG (mark 2 version) which I bought off a forum member a few years ago. It came without a case so I bought one, put a UV filter on and put it away. I have never actually taken it out or used it other than to check it worked by snapping a neighbour's aerial when it arrived. I've cut down on my Pentax gear and sold a few lenses to other forum members. PM me if you're interested

Thanks to everyone for the suggestions, I've now managed to source a suitable lens, which is one of those suggested in the replies.

No suggestions for the DA* 60-250mm. Rear baffle removal is dead easy to do, even I managed it and a great telephoto that's weather sealed also.

Missed that, brain fog and Covid, that's what I'm blaming it on

I've just acquired another K-1 Mk1 (have 2 now), so am thinking about ditching all my APS-C kit, including all of my APS-C lenses. This leaves me with a slight issue in that I will be lacking a high quality full-frame telephoto zoom lens, something in the region of the 70-300mm focal range. I have a Tamron Di LD 70-300, which for what it is (a cheap lens) performs miracles, but does suffer from the dreaded purple fringing and the max aperture is not very wide. I also have a Pentax 80-320, which I do like very much, but again it's not the last word in IQ.
Can anyone suggest for me please what lenses I may be able to find that will better my two existing telephoto zooms for image quality and max aperture, and will work at all focal lengths on a K-1 without vignetting.
Thanks in advance for your advice and suggestions.
Kind Regards
