Hey guys,
Thanks for the helpful replies. Ken, this is the first time I have heard that some 2x anamorphics are wider than others? Do you mean the angle of FOV, or the width of the rear element? To clarify, from what I understand, the rear element of the anamorphic needs to be larger than the front element of the taking lens, otherwise it will vignette? From what you're saying, sounds like the 16-D is a lost cause on S35, I'll have to shoot MFT only on my adapter.
I'm frustrated because the front elements of the lenses I mention are smaller than the rear element of my 16-D, and I still get thick vignetting. My only 58mm lens is the Minolta 58mm F1.2, which has a front diameter of 55mm, much larger than the 49mm 16-D rear element, so they are just incompatible, correct? My only 85 is the Rokinon with a huge front element so I figured it should vignette badly, though I will have to test my assumptions about that ASAP.
So elgabogomez, if I understand you correctly, the standard Cinemascope ration is 2.4 or 2.66, so cropping in results in a 'standard' ratio. That seems very liberating, since I can still use a 40mm like you said and get some extra width from the anamorphic adapter. I was hoping I wouldn't need to crop in during post, mostly because my cameras are still HD. Once I upgrade to a 4k camera like A6300 or A7RII I think can live with that compromise.
