Quote:The Samyang 85mm f1.2 avoids the heavy vignetting by only being available with the much wider EF mount. It vignets less than the Canon 85mm f1.2, apparently. :ph34r:I'm sure most Nikonians wouldn't mind higher vignetting. I guess Samyang went the Canon-only route just because the lens' huge rear element and the narrow F-mount are physically incompatible.
Talking about vignetting: yes, the AF-S 105 vignettes wide open, of course. 1.8 EV, to be precise. However, if that's the lens' only flaw and nothing else shows up during field-testing (like terrible flare for example), it's still on track to a 5-star rating
