Here are a few from the K 50 1.2 I picked up a few weeks ago. I know some think it's a bit of a novelty lens, but I think I like it. Build quality, of course, is much better than the FA lens, and I think it behaves better wide open. Not that I don't like the FA, but let me get blasphemous here and say that some of the buzz might be exaggerated. I'm biased towards MF lenses, though.
You could buy the somewhat rare K for $250 and, if you didn't like it, resell for no loss at least. You could buy the FA anytime for about $200 and resell for slightly less. I bought the 50 1.2 as part of an outfit with five other lenses included, fully intending to sell it to recover the cost of the whole package. Well, guess what.
I've not posted before, so let's see if this works:
ISO 400, 1/90 sec. wide open or close to it.
ISO 800, 1/90 sec., wide open or close to it. You might be familiar with the Seafair pirates in Seattle?
ISO 800, 1/45 sec., wide open or close to it.
I'm not certain I have many shots from the lens that aren't high ISO and pretty wide open, but if I can turn any up I'll try and post them.
