Quote: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.That is what I am saying, making the back element smaller gives more vignetting (less illuminated corners) and mechanical vignetting (term used to describe the cutting off of the bokeh discs towards the edges, creating cats eye and more funny shapes and causing a "swirly" effect).
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
I know that the light fall off and swirly bokeh are its only faults. Like I said, lovely lens, and as i pointed out, both the "fault" of the narrow mount diameter.
