Further to my previous post, my "Cyber Monday" HD FA35 f/2 arrived from Amazon UK yesterday. I only just got around to opening the package, checking it over and testing it, about an hour ago.
I knew the lens came with a hood, but was pleasantly surprised that a carrying bag is also included. Build quality is good and quite solid - it feels exactly like you'd expect; an FA35/2 with slightly different texture. The focusing ring feels nicer to me than my FA50/1.4 and an FA35/2 - smoother and better damped; but that could simply be due to this being a new lens. Certainly, the textured rubber focusing ring is much nicer in use. With AF, it was already quite accurate at zero fine adjustment on my K-3, but -2 seems to be spot-on... or maybe -1; I'm still testing to decide which. Optically, I pretty much knew what to expect, both good and not-so-good. The not-so-good includes busy-ish bokeh transitions when shot wide open, and fringing on high contrast edges at wide apertures. It's not likely to be an issue in most use cases, and is nothing that a good raw processor can't deal with. Contrast is better than I'd expected, even wide open.
Overall, it's a really nice lens - clearly an older design, and probably wouldn't satisfy those who want D FA*50/1.4-level performance across the frame at all apertures... but I think it'll work very well for me. I haven't had an opportunity to use it properly yet, but initial testing suggests it's a good copy. So... I'm very happy
