An inexpensive K 50/1.2 is going in the marketplace. Not affiliated with the seller but I have owned the lens and it's a "cracker", as some say.

If you have more money, buy the FA43 Limited.

For even more, get the FA31 Limited.

Why has no-one bought this?

Many fast lenses have this issue but it's absolutely no reason not to buy one. First, once can take shots where it is not an issue. Second, one can look at photos at realistic sizes (eg. not pixel peep) and never be bothered by it. Third, one can remove it in a trice in PP. Four, one can shoot black and white.

My FA77 purple fringes like a beast if I let it. But I wouldn't trade it for anything.

(Full disclosure: I would trade my FA77 for the 200mm macro or some other lens of vastly inflated price. But only so I could make a killing and repurchase the FA77.)

Choosing An SD Card might help.

And I too use MyMemory for their prices and service.

Actually, you haven't been able to get it for years. When rarely it shows up used it fetches three times its list. I am sure it is nice, but there are cheaper options. Namely:

Vivitar 135mm f/2.8 Auto Telephoto Close Focusing [M42 or K]
Pentacon 2.8/135 [M42]
Vivitar Series 1 135mm 1:2.3 [M42 or K]
SMC Pentax 1:2.5 135mm
Super-Multi-Coated TAKUMAR 1:2.5/135 (model 2)

I can get the shot with a prime much faster than certain other shooters who need to try different zoom settings, machine-gun 40 shots of basically the same thing and chimp a bunch of exposures.

Inevitably these are the same people using a camera that beeps with every action... drives me crazy!

Primes have the advantage of weight, size, ergonomics, fast aperture and rendering. I carry my camera with me everywhere. There is no zoom that would fit into my bag that can beat any of these:

Vivitar 24/2 [Komine]
FA 43 Limited
FA 77 Limited
Vivitar Series 1 105/2.5 Macro [Kiron]
Vivitar 135/2.8 Close Focusing [Komine]

To which can be added lenses I do not currently own:
A 50/1.2
FA 31 Limited

The only zoom I use is the DA 12-24mm and while it cannot match any of the above for quality it wins by covering a range none can manage.

As for "limiting" I am quite happy to leave the house with only the FA77. Then I know it is my ability, the light and subject availability that are the constraints, not my equipment.

Cameron deliberately used a soft focus technique for her portraits, including being OOF. My understanding is that she was criticised even in her own time for this, and that it took some time for appreciation to grow. I would not call this poor technique since the methods and result were exactly her aim.

Maybe a better and more recent example would be sports and journalism photos, where precision of representation is a standard criterion. Lots of shots of iconic value would never pass muster with an editor today.

Er, sorry for straying. Came back in to the thread on this page and forgot to look at the actual subject line.

I offer you £450 and the chance to make a tidy profit.
