I too have this lens since this week. As there wasn’t a K-1 specific review I thought I should add my thoughts. Before purchase I read a few reviews, including these:
This is my first Samyang lens and my very first impression was that they skimped on packaging, it looks cheap. The supplied accessories are a flimsy pouch and a plastic hood that seems thinner than most. The build quality of the lens is fine. The aperture clicks nicely but does jump from 1.4 to 2.0. Focus is nice, not too loose or tight. From infinity to 1 meter is about 1.5 cm, after that its quite a throw to the closest focus of 25cm. I have not tested the infinity stop yet. I have seen on youtube that this is something you can adjust yourself should you wish.
The Pentax-version has a A setting on the aperture ring — which not all mounts have — so you can use manual exposure and aperture priority on the camera. This way you can select 1.6 or 1.8. Focus confirmation works — again which not all mounts have — but only on the central AF point. Precise focus is hard with the optical viewfinder because it is a wide lens. I used Liveview for most photos below (if not all).
I had read reports of poor quality control by Samyang so I was eager to test it first for obvious defects. The first results exceeded my expectations and I could not find anything unexpected. On the contrary: centre sharpness was beter than I was led to believe from my research. There is a slight veil at 1.4 and contrast is somewhat low but is excellent by 2.8. Centre sharpness seems to peak at 4.0 in the middle and the corners follow at 5.6.
Colours are very nice and out of focus rendering is nice and smooth; the rounded blades working as intended it seems. There is quite some distortion but luckily Lightroom comes with a lens profile that can fix this easily. That profile cannot completely correct aberrations around dark tree branches on overexposed grey skies.
This is not a cheap lens (which lenses are now a days?) but what is does, it does very well. My first impressions were better than expected and I am looking forward to seeing how well it does at astro photography.
About the cons and rating
I listed manual focus and size as cons. Yes: you know what you get in advance but I would like these optics in an AF lens even better. And yes: the size is comparable to Sigma, Canon and Nikon 24mm f/1.4 lenses but we as Pentax users are somewhat spoilt with compact primes.
I would be very hesitant to rate any lens a ‘10’, for that it must be perfect. My ‘9’ might be another’s ‘10’.
PS: Should you have a specific question regarding this lens, feel free to PM me.

***Update per March 2014****
I have used and tried de 8mm, 14mm, 16mm, 85mm and like all of them
This 24mm was on my wishlist...but I waited untill the price dropped appr. to the price I just paid.
The field tests have been (again) positive on this new item...and I agree with all of the '++' and some '-' that have been mentioned (e.g. Lenstip):
++ IQ is very good across the whole frame and corners
++ you can focus closely on subjects
- it takes time to focus correctly (the lens has a long throw...and adjustment to the optimal focus needs to be done using sight focus screen...maybe Katz-Eye with Optibrite would be an improvement...but in my case I will just go for the practice); **Update**: I have bought the KatzEye and also use the LiveView/Info button approach; this works ok.
Here's a close focus:
Here's an example with moving objects; It takes time to focus correcly on the K5..but with some practice you will succeed
like this example
**Update**: And recently shot with K5IIs:

@f1.4: contrast is a little bit low, sharpness is okay (not as sharp as my Samyang 35mm f1.4)
@f2: good contrast and sharp
@f2.8: very good contrast and very sharp
@f4: as sharp as possible
I love this lens. I love my Samyang 35mm a little bit more, but this one comes with me if I just want to take one lens with me. It is 36mm (full frame) and so it is ideal for walk around. F1.4 allows you to make sharp pictures in dim light, but image qulity is better with f2 than f1.4 (but that is very normal for such a fast lens). It is expensive for a full manual lens, but it has an A-Setting so you can choose your aperture by your body.
I have a lot of fun with this lens and I pray for a long life of my copy.

Very interesting lens, producing great image quality.
IQ is definitely superior to Sigma 24/1.8 already in the center but mostly at the edges and in the corners. Same applies vs. FA*24/2.
Fully usable at F1.4.
Sample full res at F1.4:
Is large and heavy though:
But keep in mind that other camera manufacturers 24/1.4 are even more heavy and do not offer image stabilization.
Better than with the Nikon/Canon versions you can use Av Mode and set aperture via the camera as it has an A-Setting.
It also correctly writes the aperture data into the picture exif metadata.
Can be used quite well using a S-Type focussing screen.
Edit: I created an Adobe Lens correction profile for the lens and submitted it to Adobe, so it should become available any time soon through the lens profile downloader. Say goodbye to distortion, vignetting and cas.
Edit2: Here an idea of the bokeh, which I like a lot:
