Best budget options for a prime 30-35mm f1.2-1.8 AF lens for Pentax APS-C?

I'm looking for a budget (under 200$) 30-35mm f1.2-f1.8 AF (no MF leses) lens for My K-3II.
I've got the f2.8 zooms covered, but when it comes to low light, none of them are ideal. I've been looking at the Sigma 18-35mm f1.8 which would be amazing, but besides the AF issues and the weight, it's extremely expensive. The 35mm f2.4 is nice, but not fast enough. And the 50mm f1.8 is not wide enough for everyday use (for me, anyway).
That leaves some sigma/tamron primes and perhaps some older pentax primes.
What would you recommend?

Not saying it isn't out there, but your budget is very low for a fast prime with AF. When I saw your post I was ready for my standard answer... (DA 35 2.4) The only options I see for you are the MF Samyang lenses. The fast 35mm and under lenses are expensive and your only option would be to find a used deal somewhere.

Probably the cheapest you will get is a Sigma 30mm 1.4 lens. You will have to find this used as well. If not this, you may need to consider what you are really needing, AF or Fast aperture.

Such lenses do exist however, not at a sub-200 dollar price point. Even the cheap (but optically decent) Nikkor 35mm f/1.8G is well over $200 new.

I'm really not sure that's going to happen, at least not in the autofocus world and definitely not new. You might be waiting for a while on that one. Stranger things have happened, though - I've seen at least one example of someone picking up a coveted 50mm f/1.2 lens on E-bay for under $100, but that sort of luck is rare.

And there is a good reason that lens is cheap on the second hand market: optically that lens is only sharp in the center - and soft everywhere else....at all apertures. Not much difference from a lensbaby.

There is a sigma 30mm f1.4 for sale in marketplace for a little over your budget. It's $250 but maybe try to negotiate a lower price.

For Canon en Nikon there is a cheap Youngnuo 35mm F2 €129 in The Netherlands. But the best budget lens you will get is the DA 35mm F2.4

For all options, no matter whether AF or MF, you should carefully read all available user revues. Many of these are quite soft fully open.

Depending on what you will use it for, this could mean you would not gain much compared with the 2.4/35. You may have to close the aperture to at least 2.8 to get really sharp pictures. And even then maybe only in the center.

perhaps this should be looked at in a slightly different light. Perhaps the best option is the 35/2.8 macro but use ISO 200-400 to get access to low light. Very sharp lens that perhaps offers what you are after from a low light on a budget veiw point.

These are your options, and none are under $200. Even the super affordable, plastic fantastic DA 35mm, with only f2.4 is not far from $200 brand new.
OP is asking for a unicorn. IF anyone finds an AF lens around 30mm, faster than f1.8 and under the $200 mark, I'm buying a couple... and Im sure 90% of other Pentax users will be waiting in line, as well.
A used old version (not Art) of Sigma 30mm f1.4 might come closest in terms of fitting all of the criteria. If you can live with the triangular bokeh highlights

One option to consider is the Samyang 35mm f1.4 - fast, big, not super expensive. But it has no AF. Kerlee will soon start selling the 35mm f1.2, not super expensive, but again, only MF. And both of these are big lenses.
Basically, these are your only options, the ones mentioned in the quoted text, and in the previous paragraph. None of them fit all of the criteria, but they fit at least some. Good luck.

Write a note and leave it under your pillow at night. Maybe the lens fairy will leave one while you sleep.

I know Digitalis hates the Sigma 30/1.4, but I like mine. It's practically useless for landscapes at any aperture, but quite nice for taking pictures of "things", near the center of the frame, and having the background nicely washed out. It's my go-to for indoors family gatherings.
