I have to respectfully disagree with your take on those old super-speeds :)
I love the way old glass looks on an Epic.
I use to own a set of Zeiss "b-speeds (I think they were the predecessors of the MK-1's you used). In terms of pulling focus they were absolute shit... 1/2 turn rotation for focus and no matter how many times you had them calibrated they never seemed to hold.
On the other hand they were soft on skin and fell off beautifully around the edges (both focus and light) - I grew to love them for this reason.
These lenses were essentially doing (optically) what a colorist may be asked to do in post (adding mild softening and vignette's). Obviously they should be used only when you're fully committed to that particular look & they certainly don't compare in any respect to Master Primes.
You wrote in your original post: "So the moral of this post is.. sometimes.. not all the time. Bad lenses actually look good... but are saved by the EPIC's 5k image quality."
I would re-phrase and say: So the moral is, sometimes, old lenses actually look better and enhance Epic's 5K image quality.
I don't mean to imply there is anything wrong with the image an Epic produces (I love the Epic)... I'm just saying "good" is subjective and depends on what look you want.
It's all very subjective.
PS. Your footage looks great.
