    No disrespect but if what I'm saying is untrue, Jarred's findings are untrue just the same...

    Front element moves within the housing.

    The lens moves back and forth, but within the housing, it never protrudes from the housing. The lens body stays the same length at all times.

    It's not 'internal' focus, the lens has a cover!
    Vantage has some Leica macro lenses that they claim to be internal focus, however they are just still lenses that move forward in a barrel.

With that much being said, you can still get some pretty images out of this lens.

    There is no vignetting when aspect ratio is 5K Wide and below.

    Correct Joseph, as you know I love to shoot 2:1, so yeah I should have read a bit slower what He posted, I just sow 5K, but I do shoot 5K 2:1, now 5K Wide, so there is absolutely no vignetting there.

    Not even tested on 5K, which right now as it stand is the new 5KFF... So I must apologies Carl for misleading you on this one, my Bad for not carefully paying attention on what you were asking, and this time Joseph is correct in correcting me... ;)

    The hard vignette is apparent only on 5kFF at 17mm to about 18.5mm

    I'm not denying that. What I said earlier that after zooming in, you have a diffused looking vignette on 5KFF.

    When the v2 is shipped from RED upon its upgrade over the weekend, I'll be happy to post a demo Motion/Stills of exactly what I mean...unless someone wants to beat me to it.
