There's also the Nikkor 85mm f/1.8
Nikon | Telephoto AF Nikkor 85mm f/1.8D Autofocus Lens | 1931

B&H sells it for $450 and it's supposed to be a very nice lens.
I just picked up a Pentax 77mm Ltd for almost twice that price, and would have preferred 85mm focal length.

IMO a reasonably priced 85mm f/1.8 (FA not DA) is a glaring hole in the Pentax lens lineup.

B&H Photos sells:

85mm f/1.2L II USM from Canon for $1830.
Nikkor 85mm f/1.4 AF-D IF - $1025
CZ for Sony/Minolta 85mm f/1.4 with Auto Focus - $1300
Plannar 85mm f/1.4 Manual Focus for Pentax & Nikon - $1033

Why are these lenses expensive? I think there’s a large demand for quality portrait lenses and the companies know this.

I know the 85mm f/1.8 AF-D is not very expensive and it's a very good portrait lens. It is priced at around $400. If you can get it to work on Pentax getting good results but it may be easier to buy a used D70S or D50 which are not expensive.

Am I correct that this thread about 85mm glass doesn't even mention the Vivitar/Samyang/Opteka/Bower/Rokinon/Polar/Sakar 85mm f1.4 lens? (Not that I have one, but still, seems worth mentioning...)

Sorry for a bit of an off-topic, but what does "pre-set" aperture (diaphragm) mean?

A preset aperture lens is a lens with a completely manual dual aperture control. One control (pre)sets the aperture to a certain level. The other control actually opens and closes the aperture. The reason is so that you have a convenient way to focus wide open while easily returning to a specific stopped down position for your shot. So you decide your aperture and set it. Then you focus with the aperture open and close it down to its preset to meter and shoot.

Here you go: Zeiss ZF 85mm f1.4: First Impressions

Canon 85mm f1.2 L (Mark II) vs.
Pentax SMC-A* 85mm f1.4

They seem to share the blows.

First, I've wanted the Nikkor AF 85/2.8D for my D40x kit for quite awhile but I've read several comments stating it's a little prone to CA. I think a person would just have to give it a try.

Secondly, generally speaking the 85mm focal length falls between those of normal and true telephoto lenses. The manufacturers don't seem too anxious to publish lens diagrams that really show much more than a few blobs lined up on a centerline so it's hard to tell what's what. The Nikkor 85mm mentioned above has a 62mm filter thread whereas my 50/1.8 Nikkor still has the old 52mm thread. Jumping up to the older 105 Micro drops back to the 52mm thread. It's hard to tell at what focal length most manufacturers shift from their normal or long lens formulas to their telephoto designs. The 85/1.4 designs on the market use large elements which require very high grade glass and a limited use of plastic and hybrid elements. Add it all up and you get expensive.

By the way, I don't mean to sound any alarms or anything but I happened to check the KEH Incoming Pentax page and they have an A85/1.4 on the way. To quote the King, it's now or never.

I agree! I even made a thread about it before seeing this thread.

Nice to see someone else agreeing with me
I said DA, though, since I doubt we'll see any new FA lenses before Pentax releases a full frame camera.
