Review on Samyang SY8MBK28-FX 8mm F2.8 UMC Fisheye II Lens for Fuji X Mount Digital Cameras - Black by Craig Shah

I am very impressed with Samyang's 8mm fisheye lens. It's manual focus only, but with an 8mm lens that's not too much of a problem (although a proper distance scale with depth-of-field markings would be nice). I mostly just use the sharpness indicator on my XE-1. At f/5.6 it's pretty sharp all around with little light falloff in the corners.
