It's pretty amazing! Very little to no CA wide open and it's both sharp at near and far distances. AF is silent and fast, OOF areas are buttery smooth, it's tack sharp wide open and sharpens up nicely when stopped down. Colors are warm (almost Nikon like), but can easily be adjusted in raw. I like this lens a lot better than the Sony 85mm 1.8 FE, which I found soft at further distances. The Samyang 85mm can easily be used as fast short telephoto lens due to it's sharpness at all distances, minimal CA and fast focusing. I also use back focus Eye-AF with the lens and it's able to stay locked on even with obstructions in the way.
John, I think you'll like this lens a lot especially if you have the Samyang USB dock already!
