I imagine Pentax K-1 users can be divided into two groups. "Pros" who use the f/2.8 zooms, and "Filthy casuals" like myself, for whom the FA31 Limited is pretty much the apex lens of the K-mount catalog.
Viewed in terms of the f/2.8 professional zooms, the HD Pentax-D FA* 50mm F1.4 SDM AW is neither expensive nor especially large. This is a perspective I can't relate to, and this review is not written for that user group.
'Cuz this lens is HUGE I tell you! It's about the same size as the micro-Nikor 105mm F2.8 AF-S, and slightly heavier - and that micro-Nikkor is already a massive lens. On a K-1, you are toting 2 kg for the day. The most charitable way to put this is: it's manageable. It's not something you get used to (picking it up invariably elicits an "oof" as the wrist muscles tension) but it balances and handles well enough that's it's not unpleasant. But would I rather use a lighter system? Yeah.
The performance is everything you'd expect for an optic of this caliber. I spent a lot of time reviewing sample photos online before buying this, and I'd have to say I was pleasantly surprised. I was expecting the color fringing to be more of a concern than it is, and nothing can quite prepare you for the level of absolute clarity this lens delivers.
Inevitably, though, we get tangled up in notions of value. This is a 50mm F1,4. Perfectly good alternatives already exist on K-mount. The FA43 limited being the obvious choice, together with the FA 50/1.4, the DA 55/1.4 (works on FF), and older manual focus primes.
The silent, fast, and accurate autofocus of the HD 50/1.4 must be acknowledged as being worth paying for, however, and the weather sealing (WR) is unique to the available Pentax standard prime lenses. The manual focus is also extremely precise for an AF lens. So it's not just optics that the price reflects. But it's still mostly the optics.
So... back to value again. The basic issue here is the high quality of the cheaper alternatives. I mean, really - how many people are staring at their FA43 thinking - "no, this is not acceptable - I have to have something better"? To my mind this makes the Pentax HD 50/1,4 a hard sell for anyone outside of the group of people who above all else want a modern, weather sealed lens and for whom paying $500 more over a FA43 isn't really a big deal.
Bottom line: if you can stomach the price and the weight, this is a great lens.
