The video on top and the video you can find here on vimeo are the first shot with the SLRMagic 28mm f/2.8 pancake. It doesn’t look bad at all or not? By the way, I have been told by the guys from SLRmagic that this lens is not the Mitakon 28mm f/2.8. It’s an improved verison of it.
You can get that lens on eBay only (Click here).
