I have a Samyang (European branding) 8mm Nikon mount with removable hood and electronic circuit that communicates with the camera
There were some complaints that in the old version you needed to set infinity focus by adjusting the mechanical stops in the barrel. I didn't need to do that. I have found myself using this lens more and more, even for situations where I would not normally have thought of using a super wide angle lens
If your manual focusing skills are good it is an amazing lens, especially on Nikon because the chipped version has all EXIF data. This comes in handy in LR, and even the non-chipped works well on Nikon. I have not used any manual focus lenses on my Canons but I hear it may not work as well as Nikon. But the lens itself is amazing, it renders skin beautifully. I am now a Canon shooter and the 85mm 1.8 is an amazing bargain, critics say it has too much fringing, but it is no worse than Samyang/Rokinon and the AF is amazing. I am more than willing to sacrifice 2/3 of a stop for more focused photos.
it has auto aperture but does not have auto focus -
I don't believe that is true (disclaimer, I used Canon and missed Nikon in the first post when I originally answered).
My understanding is the Nikon version is chipped, so it will report the aperture, but it does not have an automatic aperture.
By automatic aperture, I mean if you set the lens at f8, the lens stays at f1.4 until you press the shutter, and then it closes down to f8 for the expose, and then it reopens to f1.4 to focus for the next picture. Per the Nikon version description at http://rokinon.com/product.php?id=2 " The lens is manual focus and the aperture needs to be controlled directly from the lens"
I have had the 85mm f1.4 for the past few years (Olympus 4/3 mount) and it's a fantastic lens, got it for $250 when it had just come out, now it regularly goes for around $375. Sharp right from 1.4, although I get some ghosting there, so I usually stop it down to f2 unless I need that extra stop.
Check here for samples, most of these are mine. I put them under Vivitar 85/1.4 because pbase doesn't have Rokinons catalogued and Vivitar is another name the same lens is marketed under.
Ronkionon is just a rebranded lens, like Bower, and several other brands. Samyang is ghe OEM for most of them. They used to be known for pretty budget-oriented lenses, but have really turned out some good glass lately. The 85 f1.4 is in par optically with last-generation Nikon or Canon glass. Most Samyang lenses come in an 'electronic' version that allows electronic control of aperture, auto-exposure and electronic rangefinder operations, but only with Nikon.

When the BJP ( British Journal of Photography ) magazine had an extensive testing process it found the image quality of the Samyang 85mm F1.4 to be superior to the Nikon AF-D version ( the G was not released back then ). Where it lost out was no AF.

Don't know where you get that. I had one and I have to say its as good as the best of portrait lenses out there with a warmer tone but not superior. Also it does not autofocus which I find detrimental to my workflow.
Could not find anything on dpreview, where they did an A-B-C optics test that proves that any Rokinion lenses are superior to any Nikon, Canon, or Zeiss lenses.
They are cheaper by a mile though, and I don't see how Rokinion can make superior lenses without using good glass, which is why Nikon, Canon, and Zeiss lenses cost more. Just saying, as I do have a Rokinion lens, that I bought years ago, when I couldn't afford the good glass.

Wellsome times you can. Most fixed lens designs from all manufacturers are copied from Zeiss, who had their patents taken off them after WW2. Which is why almost every maker has, for instance a 50mm f/1.8. Zooms are a different matter since they have been designed since then.
Fantastic image, by the way, it almost makes me want to go out and buy one!
