The Pentax SMC A*300/4 is a gem!

If you can find one the Sigma 100-300mm F/4 is very nice paired with a K-1 full frame.

I saw one in the used equipment store for Henry’s in the time BC (before COVID). I think it was going for about $600 cdn. You might want to check in line if interested.

I really love my 300mm f4.5 F lens. Incredible and a great manual focus as well as autofocus lens.I see a couple without the tripod foot on ebay for sub $600. It's a stellar lens.

The 55-300 DA is also a very nice cropped lens and very inexpensive for what you get.

Similar to previous comments I would venture the best choices begin with DA 55-300mm, other older Pentax variants, other K-mount variants such as Sigma.

A little known / not very popular film era lens that used to offer decent performance given its very low resale value was the 'Olympus-OM Zuiko Auto-T 300mm F4.5':

Prior to the MILC popularity excellent copies used to sell for USD $60. However it appears that the going rate is now about $130. This also requires a 'Leitax' (USD $70) or similar adapter. Consequently running the total cost up to about $200. Likely not so great against other prospects. The lens can be subject to very strong CA / color fringing in some conditions. However it is also capable of delivering some very good results in less contrasty lighting. Ironically I didn't care much for the results of the lens on my Olympus film cameras, but I have experienced some very good results with the Pentax digital aps-c sensor in my K-5. Examples follow- including a very bad CA / purple fringing case:

Aye, optically the tair is the one. But they aren't just like a tank, it IS a tank. The 3A/300A is the one to get, that is basically a (variant) t-mount - I haven't tried a photosniper with its distinctive focus mechanism (though they are a bit cool..). But the bug with the 300A's is that there is a felt wedge around the inner focus barrel, with time it gets gummed up and sticky and then focus movement is like a misfiring wartburg with the handbrake on.
I have both models - my 300A is every bit as gummed up as you described. The Photosniper model is pleasant to use and most importantly both are sharp from wide open f4.5.

There is also the Pentax-m 300mm F4. Same as A without the A-contact. But I wonder when I see the prices the good 300mm lenses go for, it would maybe be a better Ideal to look for a used DA* 300mm F4.
