I need to get myself around to downloading/installing PT Lens - does it correct for color shift, too? I notice my 14mm has a slight cast to green in the corners when I shoot into the sun.

Not sure, but LightRoom should with plugin from Adobe. Or Capture One. Or CornerFix.
Yes it is, but you loose quite some angle with this correction here, making it a 18 or 19 mm lens. And that's a pity. But unavoidable in architecture pictures with such distortion I suppose.

Agreed - there is a fairly significant crop, and that is a concern of using any super wide-angle. It is not so much due to the design of the Samyang / Rokinon 14mm.
This is a before / after of an image that was treated with PTLens, and then with "Adaptive Wide Angle" in Photoshop CS6. My take on it is that the most appropriate correction of the distortion depends on the image subject.
So i'm strongly considering this lens, which retailer do you guys suggest in case one needs to return the lens? Also any tips on how to quickly tell a good vs bad copy would be appreciated!
I (still) think that B&H has a great return policy, but so do Amazon and others. My 14mm has blurry right edge wide open and I consider that not ideal, but I did not find it bad enough to return the lens. The blur disappears at f:8.
I just received my 4th copy from B&H. The previous ones either were decentered or had asymmetric field curvature. This new copy isn't perfect either - one corner is smudged...but I think it'll be good enough. Here is a 36MP image from my D800 at f/8:
I bought one of these second hand and it won't focus to infinite.. at all.. only focuses on things close up.. gets slightly better stopped down but things far away are out of focus, with the focus ring as far left as it will go
I tried to buy a used one, but people kept bidding them up to near new prices, so I got a new Rokinon from Adorama. Tack sharp at f/16 and f/2.0, close and infinity
just keep trying. When I bought mine used here in January, the guy I bought it for used it for a shoot. He tested it for the variances - and it was 100% working.
Pros and cons of buying new is that you can return it, but may have to go through a few copies. Buying used you can know it works, but they don't come up for sale very often.
After all these 14mm shots, given the thread really doesn't say 14mm, I am going to go off the reservation with some different kind of Samyang love - this is all with the Rokinon 85mm f/1.4, picked up used for $170 a while ago when I still had a DX body, and it is probably still the sharpest lens I own

Actually, it says 14mm right in the thread title. Good shots with that 85mm though, SR-71 will always be my favorite jet.
I had the 85mm when I had my 1Ds - and it was great and sharp! I really like the samyang lenses. I am thinking of getting the 35mm next, but don't know. the 24mm would be nice as well
