Purely speculation: Even if the optical formula is the same as the older one, they may be making it with better tolerances and thus may get better results from that.

What does SA and COF means?
Is it me or is the curve only on one side only, and more visible vignetting on the other side..The curve appearing on one side is probably due to a slight tilt of the camera. The vignetting looks about the same both sides to me. Be careful as the image is cropped on my forum view, so you have to move the slider to see all of it.
Thanks for the info. I didn't realise they had updated the design since I got mine early on. That makes it a bit more interesting for full frame use, even if it doesn't cover the whole sensor.Attached shows the coverage of the Samyang on a full frame body. You can kinda see the image circle it gives which you can expand into if you cut off the hood. There are some examples out on the internet of people who have cut off the hood.
The latest Samyang fisheye has a removable hood.

There are some examples out on the internet of people who have cut off the hood.The Rokinon (a.k.a. Samyang) is a crop sensor lens. It'll fit on a full frame camera but you get a small rectangular image due to the built in lens hood. If you cut off the hood, you get a cropped circle in the middle instead, but still wont cover the whole sensor. Note the lens cap fits onto the hood if you're considering that. All in, I wouldn't recommend this lens for a full frame sensor, unless you have a very particular need for it to fill. It is great value for crop bodies though.
On the other hand, it's on sale for $229 at adorama today.
