I think the price is fair for what I'll get. And I know one that was on sale a few weeks ago in The Netherlands, that went for EUR 850 too. That was the first one I saw for sale for a few years. But I meant to say that on the worldwide market, there are always a few available. Not necessarily cheap, though.
this is probably one of the things I envy about you guys in the EU. you got more access to some rare lenses which are harder for us to find (some for a cheap price). although you have to pay double for the new lenses that we enjoy here of paying less.

Yes, being a collectors' item could retain or blow up it's value, but until when? it can really be tricky as well. the C/FD 85/1.2 for example was only selling for a short change a few years back and could get one easily for a bargain ($50-$200). this was because the FD mounts were deemed unusable for the modern dslrs a few years back. now they are starting to jack up again starting from $500 to as much as over a $1,000. this maybe have to do more on usability on the new systems due to adapter use rather than collector's value or both.
Quote: Agreed on the price and availability, but not on the optical design. There haven't been huge leaps in optical design; many lenses still rely on design principles which are older than most of the forum members. What I still don't understand is why nobody makes APO versions of a 50/1.4 or 85/1.4 so that these show absolutely no CA. I think this is due to the fact that supercorrected lenses are sharp and free of PF/CA, but have a not so desirable bokeh. This is especially important in f/1.4 lenses.
I'm waiting for samples of the Sigma, but I think I will have a hard time justifying a purchase
APO version for such lenses could be tricky especially on the IQ compromises you've mentioned, aside from the cost which would make a Sigma 50/1.4 sell for around $1,000 due to APO production costs (rough estimate). making the image totally free of CA/PF could really impact bokeh rendering, especially at such wide aperture opening (f1.4).
as far as CA/PF is concerned, some optical design on some lenses have pretty impressive control over CA/PF. one particular lens that I'm impressed with is the Sigma 70/2.8, which also have a pretty good bokeh. so Sigma might had used the CA/PF control concept on this lens and could had improved CA/PF control further on the 85mm without sacrificing bokeh.
let's hope that the added SLD glass, mold glass elements and rear focusing system that supposedly would combat CA/PF perform as it is advertised.
I think it would be a hard time for you to consider a purchase, especially if you already have an FA*85. I would be in the same dilemma as well if i were in the same position.
