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.

| | 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.

| | 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.

| | 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'.

| | 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.
