It's big. It's really big. And heavy. It's really heavy. It's very similar in size to a Pentax 6x7 135/4 Macro lens, and half again heavier.
It's really big and really heavy. Mounted on the K1, it's really bigger and heavier.
Auto Focus seems quick enough, I don't have anything to compare it to. It's very quiet. There is no torque twisting, the 7.5 times more powerful motor is all good.
Manual focus is excellent. It has really nice damping and is absolutely slop free. It's as nice as any manual focus lens I've used.
In use, the K1 with this lens is a heavy rig at 1920 grams. That's 4.23 pounds. It's heavy.
However, it does balance nicely. For most people I wouldn't think this is going to be an all day walkaround camera/lens combination because of the weight, but because of the weight it's a great handholding lens.
I did a very little bit of handheld shooting, but I tend to use a tripod most of the time, and this time was no exception.
On a tripod, the K1 and D FA* 50/1.4 is a well behaved combination. I am using a fairly heavy Feisol CF Tripod and their large ball head.
Prior to this I hadn't liked this head very much as it felt a bit notchy. With the 4 pounds of camera and lens on it, that goes away and it's as smooth as polished glass.
Handheld, the weight works to advantage. There is a lot of inertia at play tp keep things steady. I noticed the same effect with my Pentax 6x7, which weighs in at ~2500 grams with the standard lens and film loaded.
I haven't tested it, but I expect the K1 with this lens could be handheld a stop or more slower than the K1 with the FA50/1.4
This is all well and good, but what is a lens for but to produce images? This one is superb for that purpose. It has meltingly beautiful bokeh. It's extraordinary. The previous bokeh king, the 77LTD has met it's match in this lens. The lens is startlingly sharp wide open, which serves to accentuate the out of focus areas. Stopped down to f/5.6 and this lens is sharp enough to shave with, while at the same time still giving very smooth out of focus areas, providing there is sufficient seperation.
Contrast is very high with this lens, colours pop right off the screen. I've only made one print so far, and it is vibrant and stunning.
This is an expensive lens, and the law of diminishing returns does hold true. F/8 is, as always, the great equalizer. If a person spends most of their time stopped down to smaller apertures, this lens won't be much of a benefit, other than giving a solid workout to upper body strength. If, like me, you shoot at mid apertures, like really nice bokeh, and razor sharp images, this lens should be on your radar.
Pentax has knocked it well and truly out of the park with this lens.
I demerited it a bit on handling because of the weight. It won't be for everyone as heavy as it is, and also for value. At the price of it, there will be many people who will pass it by.
However, if you can afford it and can live with the heftiness of it, it is truly an extraordinary lens.
Edit: This lens focuses closer than other 50mm lenses I have used. Both my FA50/1.4 and A50/1.2 focus to .45 meters ( ~17 3/4"). The D FA* 50/1.4 focuses to .4 meters (~15 3/4 inches). This may not seem like all that big a deal, but it does expand the usable range of the lens a little bit.

Just a quick first impression. I've had it two days and taken a couple of dozen shots with it:
1. The box it comes in is very protective - bigger than a Pentax KP box, with the space around the lens surrounded with corrugated card.
2. The build quality is similar to the DA* 200/300 - solid, dense barrel with smooth focus ring.
3. On the K1 it balances well in a two-hand grip. We've tried it on a KP, and it slightly overwhelms it.
4. Focus is snappy and quiet.
5. First look centre and edge sharpness is excellent from F1.4.
6. Out of focus transition is unbelievably smooth.
I'll add photos when I've got some worthy of demonstrating its performance.
Edit: price is converted from GBP with sales tax deducted. (UK price £1199 including 20% VAT)
Edit 2: photos added
Handling is fine despite weight. Out of focus backgrounds almost 'painterly'.

First to the con's:
- Yes, this lens is similar to Sigmas tries at producing lenses: large and heavy for a 50mm prime.
- Yes, it is not cheap, it falls into the middle price range.
Now to the pro's:
- Outstanding image quality overall.
- The superb bokeh quality mixed with very, very high microcontrasts even when used wide open make images "pop".
- Wide open sharp into the extreme corners, better than a good copy of a Sigma 35 Art.
- Fast autofocus, at least as fast as any other 50/55mm F1.2/1.4 lens from any maker out there.
- Weathersealing.
- Excellent build quality
- Smooth and precise manual focussing possible
- Handles surprisingly well on a K-1 and feels perfectly balanced, even better than a standard zoom like 28-105 or 24-70.
- Very pleasing color rendering.

It took Pentax quite some time to deliver a FF camera and now we are seeing the first new FF prime specifically designed for a digital FF camera. So far FA Ltd with old AF engine, no weather sealing and old designs had to be used. I still have my 77mm lens and really like the bokeh, but I was waiting quite long for the new 50mm to arrive. The wait is over - still waiting for the 85 mm and some wide angle with alrger aperture.
This is the first Pentax lens that really shines in all aspects. f/1.4 is already sharp and quite sharp in the corners. AF feels fast and snappy, focus shift is not really an issue. Lens weight is OK, feels nice on K1 - more obstrusive than the FA 50s or the FA Ltds, but a lot of glass is needed to get this performance. For the photographer I see no issue wrt weight, (potential) models may be scared a little by the size. Bokeh is VERY nice and you can use the lens from f/1.4 and down. At f/5.6 the lens is bitingly sharp, but not yet plain technical. I use the lens for portraits and street photography where field curvature is less important. As far as I can see field curcature is well controlled. Filter diameter is 72mm, a little smaller than 77mm standard that is used for several Pentax lenses. This lens will get its own polarizer and everything else is attached by filter holder. It would be nice if other lense in the expected D-FA* line could also have 72mm filter diameters.
This lens competes against Canon 50L, Nikon 58, Zeiss Otus, Sigma Art
 I need to correct the statement above after working with two Sigma 35 ART copies and looking at image from relfex 50L and Nikon 58.. So far I have not found a lens with performance to the Pentax. You may complain that f/1.4 is too sharp, but here I prefer phyical performance and apply digital filters where needed.
Add weather sealing, AF, and its a Pentax lens for Pentax cameras. Price fits performance and market placement.
A wide angle and a medium tele portrait lens are on the roadmap and must follow this lens - Pentax has many 50mm lenses in their lineup, it is time to re-cover new bases.

| Pros: | Feel and Balance on K-1, overall performance. | | Cons: | very minor spherochromatism | |
Overall Outstanding.
Has slightly more spherochromatism (green/magenta on defocus) than I was expecting, but it's very minimal and not a major concern but I guess I was expecting it to be perfect.
When doing live view preview in Av mode, it's so nice how much quieter the electronic aperture is. It's not totally silent, but it's pleasingly quiet compared to mechanical aperture models.
On My K-1 Autofocus performs much better with Pdaf rather an live view Cdaf.

This lens has impeccable IQ, definitely the best I've used. The only one that comes close is the Sigma Art and this seems to share some of the same DNA of big and heavy with stellar optics while managing to feel better balanced; I think more of the weight is in the back in that "heavy focus group" that is discussed as compared to the sigma I used.
Can't speak to how it is on APS-C but it seems like it'd be a waste of the corner-to-corner sharpness.

Only reason why i cant give it a 10 is the weight. After using it for coupe of hours with K1, i had to rest for sometime before resuming. Apart from that, this lens is a gem. The first thing that i love about this lens is AF.. in my experience, no other pentax lens was as fast as this one.

The impossible lens! When the first 1:1 images popped up on my computer screen from my first outing with this lens, I physically jumped. Wow, I never realised a photo could be that sharp. And when I scanned across to the edges, nothing changed. They are just as good! I didn't bother checking for front or back focus, as it was clearly spot-on.
And the bokeh is to-die-for. Creamy-smooth, perfectly accentuating the sharpness of the subject.
The autofocus is very accurate and fast. It didn't miss once (other than due to my own error). I haven't tried it yet with AF.S and targets moving toward me.
Colours seem consistent with other good Pentax lenses. Nothing to complain about there.
The only aberration I have noticed is some purple fringing in a few wide-open shots of out-of-focus dark features against a bright background. It is easily removed in post-processing, though unusually simply clicking the "Remove Chromatic Aberration" button in Lightroom doesn't do the job; I need to go to manual and use the slider. I don't know if this is a problem with the LR profile for this lens.
f/1.4 (575x419 crop)
Despite its heft, this is a lens that every Pentax shooter should aspire to .... unless they don't want to be spoiled.
Sorry, I don't have any portraits of dogs.
These are from my first proper outing with the lens, walking around the arcades and alleyways of Melbourne.

This is close to a reference quality lens. It is designed to excel at wide apertures where traditional 50mm lenses might struggle to produce good contrast and to a lesser extent good sharpness. Both weaknesses are mostly gone with this new lens. However you need to be careful because of the shallow DOF, which combined with a bit of LoCA can produce purply/green halos around bright out of focus objects. However, you need to really push the lens at F1.4 to see this. The colours are very punchy compared to traditional Pentax lenses.
I would say from a pure sharpness perspective, the FA50/2.8 Macro is almost as good. However, it has drawbacks such as a very sharp-edged 8-blade aperture, more blue/red CA, and finicky focus near infinity.
The DFA*50/1.4 is almost absurdly large; I think it's literally the size/weight/cost of 4-5 FA50/1.4 lenses or 2-3 DA*55/1.4 lenses. However, in addition to better IQ in all respects, it also has better AF (confident and quiet), and manual focus feel (similar to the DFA*70-200). The filter diameter is also a big step up to 72mm; compare against 58mm of the DA*55/1.4 and 49mm of the FA50/1.4.

With the exception of size and weight (which is entirely subjective), this is a FANTASTIC lens that has exceeded all my expectations. The center sharpness of this lens at f/1.4 is incredible. Beautiful compression and the Bokeh is perfectly round (no hexagons, cats eyes, etc.) and creamy. Lovely colors and contrast.
In certain settings in bright light, some slight CA at f/1.4. Nothing egregious and easily addressed in Lightroom.
Focusing is smooth and quiet. It's not going to win any races, but it won't leave you frustrated and annoyed. Calibration was needed with my lens/body combination.

Unbelievable lens - the best lens I've ever shot (and I've shot a *lot* of lenses from the 1950's era to current). This is a quick shot of my cat (overcast day even). F1.6, quick autofocus. I'm going to have to sell my 1950 Zeiss 58mm Biotar and my 50mm f1.4 8 element Takumar. Pentax + Tokina really did an amazing job building a cost-is-no-object world class lens - Happy 100th birthday Pentax! Check out the sharpness and out of focus and completely natural color. Slight foreground chromatic aberration in the metal grid in front of the cat's paws:
Overall after comparing results, this new 50mm is better than the 1950 Zeiss 58mm f2 Biotar, the 1964 50mm f1.4 8 element Tak and the 1970s era 50mm f4 Macro Tak which I also currently own. Sharpness is great on all when stopped down but the improvement is most obvious at the tougher wider apertures f2.8 and below, chromatic aberrations are good in all (sometimes very slightly worse in the newest one) but contrast is always best on the new 50 by varying margins depending on how close to the sun you shoot. While flare can be used for creative artistic shots and be superior in those cases, in general I avoid it and of course it can be added in post but not easily taken away. Autofocus, weather sealing and the coatings are the biggest areas of improvement when comparing to these similar focal length lenses from the past 70 years. Size and weight have gotten steadily worse so if you are backpacking, take the 1950 Zeiss 58mm f2 which is a tiny jewel of a lens with great results if not shooting into the sun. The flare difference in images (all shot at f4 with sun just outside upper right frame with a lens hood):
2019 Pentax 50mm f1.4 HD AW 
1950 Zeiss 58mm f2
1964 Takumar 50mm f1.4 8 element
1970's Takumar 50mm f4 Macro 1:2 (Tessar)
The above is a stress test to show the biggest optical differences as the lens options have gotten better (flare), but as I mentioned, the size and weight of equivalent focal length lenses has grown enormously. The 1950 Zeiss 58mm is an early tiny M42 mount jewel that you can hide in your fist and is great for low weight and has gorgeous results when not shooting so close into the sun and when stopping down. Check out the natural color and fantastic sharpness in this sample shot with the oldie (based on the serial number, I think this lens was made in the East German area after the war just as the Cold War was beginning and was built using parts eventually rescued by the Russians from the Dresden factory after the war. The Allies had bombed it in the infamous Dresden bombing. Interestingly, I bought this lens from a guy in Russia - via Ebay): 1950 58mm Biotar f2
crop of bird in photo above (sharper Raw, this is a JPEG): 1950 58mm Biotar f2
Update: I kept the 1950 f2 Biotar 58mm for its portability to complement the 50mm 1.4 FA D. I also kept my 300mm f4 which is a very very nice Pentax lens that I've sent in and had repaired when the autofocus failed. I sold all my other lenses on Ebay.
Another update: over time I've noticed that manual focus has a slight design issue. It is too stiff. I noticed that the initial release of the lens was delayed and in the interview with the lead of product engineering he mentioned the work they did to get the tension for the focus just right. A trick you can use is to avoid "gripping" the focus ring tightly. If you do that, it is very hard to turn. I find if I put my hand lightly under the focus ring and ensure I don't "grip" it much at all, it is more manageable. Note that the new 85mm doesn't have any issue with stiff manual focus.
