I too have been considering the Sigma 85mm f/1.4 for my next lens purchase. I think the magic for this lens is the fact that it is f/1.4 so the options given for f/2.8 lenses are of no interest to me personally. Have considered the FA 77mm f/1.8 instead of the Sigma though as it is a few hundred dollars less and a legendary lens. Also not that huge of a difference in focal length.
I would be much more inclined to buy a 77mm over the Sigma too. I just saw a FA* 85mm available and I could not pass it up. The only reason I would consider the Sigma over the others is if I needed quiet motor-in-lens focusing for weddings or something.

I would like to second this lens choice ... the older, non-is Nikkor lenses are very easy to convert to Pentax, and create beautiful portraits, at a budget price. The manual focus ring is huge which makes them pleasure to use, both outside and in-studio.

I shall mention manual-focus 85's on eBay.

* I bought a Nikkor 85/2 (CHEAP! but I was lucky) that I easily modded for Pentax mount. I've seen these sell for under US$75, and an 85/1.8 for around US$135.

We haven't heard from the OP since the question was posted -- I wonder if a choice was made? And should I mention a rather different cheap option? It requires:

* M42 focusing helicoid, probably 17-31mm (~US$85)
* cheap wide-flange no-infinity-focus M42-PK adapter (~US$5)
* cheap non-auto M42 macro tube set (~US$8)
* 75-80-85-90mm lens scavenged from MF folding cam, OR
* 75mm enlarger lens, very common ($US5-20)

I recommend the helicoid rather than cheap bellows because naked lenses shorter than 90mm often cannot focus to infinity on bellows, whose minimum thickness may be 35-45mm.

To use this stuff, run some numbers. A scavenged or re-purposed lens needs to be its focal length away from the frame (film or sensor) to reach infinity focus. The dSLR body is ~46mm from mount to frame; the helicoid's minimum depth is 17mm; the M42-PK adapter adds ~1mm. Those add up to 64mm. Fudge a little, and figure that the shortest lens to reach infinity would be 70mm. Add a 10mm macro tube, and that Zeiss Tessar 80/3.5 pulled from a trashed Ikonta will focus from infinity down to 1m maybe; use a thicker tube for closer work or a longer lens.

Just seen a APO Lanthar go for GBP 135 here in the UK on Ebay....thats got to be a good deal in comparison to something like the M 85mm. I used to have the 85mm M but prefer the 100mm M for sharpness. What about the old Tamron SP f2.5 90mm macro? Its actually 85mm...I've read nothing but glowing reviews of it, and it takes 49mm filters.

Well, I guess it's better to be 85'd, than to be 86'd, eh?

Except when I got a Nikkor 85/2 for US$9 shipped. Modding it for PK was nervous but cheap. I paid a whole US$70 for a Jupiter-9 85/2. I've scavenged a couple of 85's from MF folders for about US$5 each. Pretty close: my 90mm ELs were about US$7 each. I use those on tubes or bellows. Gotta get a focusing helicoid one of these days...

So yeah, if you go for a premium 85 at a BIN price, it ain't cheap. If you can improvise a bit, costs drop dramatically. Think outside the box, eh?

Not true, you just gotta know what to look for.
You can always consider the Mitakon 85mm f/2 a double Gauss design that is supposed to be based on the Nikkor 85mm f/2.
How the lens looks like:

As other had stated, first choice is FA*85/1.4, daylight overall use is K85/1.8. if weight is an issue then M85/2, for AF and combined with macro is Tamron 90/2.8 (or Sigma105/2.8). Flare resistance FA77/1.8. Tilt setup with Exakta80/2.8. All lenses are very sharp, if not razor sharp stepped down onw two clicks, all with different uses. Also zoom is Tamron28-75/2.8.

If you are okay with Manual Focusing,

Vivitar/Samnyang/Rokinon 85mm 1.4 offers great IQ for its price ($250USD-ish new).

I love that lens so much.

Samyang disproved that with their 85/1.4 and, as creampuff mentioned, you can also find the Mitakon at an even lower price.

It's actually Mitakon - Makinon was a different brand. I have this lens and it's a great deal - being f/2 it is also very nice and compact. I reviewed it here. I recommend it.

In my opinion, all Pentax manual lenses are far cheaper than their value, a very underappreciated brand. But, they're potentially overpriced relative to other lenses in the range.

I find the M 100/2.8 far sharper than the M 85/2. I believe that the rarity alone accounts for the price of these old 85mm lenses, and it has little or nothing to do with people actually printing photos out, and spotting any special magic.

Just printed a couple of photos of my baby, taken with the M100/2.8 taken with Fuji Acros (capable of 130lp/mm), and its possible to wet print the negatives something like 10x to get a 10x15 inch print. The background blur is lovely, even though taken at f5.6.

I can support this opinion, I also had Contax CZ Sonnar 85/2.8 and it easily is on par with 77 limited. Nice feature about Zeiss lenses (not Jena) is also T* coating, which is pretty much like Pentax's own SMC coating - both well ahead the competition.
I own the following lenses: CZ 85mm f2.8, Zeiss ZK 85mm f1.4, Pentax M 85mm f2, Pentax 77mm ltd.

I think the 'best deal' is the Contax Zeiss 85mm f2.8. If you can live with the slow maximum aperature (and manual focus) it is a gem.

It is at least as sharp as the 77mm ltd. However, it has that wonderful Zeiss colour. When compared to the Zeiss ZK, the Contax Zeiss version is (a) sharper; (b) much smaller; (c) much cheaper; and (d) much easier to use (no focus shift).

If you're shopping for the Contax Zeiss lens, make sure you get the MM version. I don't think that the AE version will convert to Pentax K mount.

Just to throw a spanner in the works, consider 75mm lenses as well, Zeiss biotar 75mm f1.5, yummo.
