In terms of a lens for interviews with the FS 100 is this a combo you would advise?
NIKON Nikkor 85mm F 1.8
SONY 16-50mm f.28
(Nikon F to E mount adapter)
(Sony Alpha to E mount adapter).
Without spending a billion dollars, would this combo of lens compliment the 35mm
super sensor of the FS 100?
And, in terms of image, what am I getting for the SONY 16mm f2.8 wide angle?
Is it too wide for interviews, and how close would I have to be to a subject to
make a lens like that work?
You may miss not having the 51-84mm range if these are the only two lenses in your kit but it is a good start. Also, while having an f1.8 piece of glass is very nice in certain situations, for interviews I find that if you choose to shoot wide open at 1.8 it is very distracting for the viewer. Usually this will put one eye in focus and one eye out.
I have found for interviews that an F4/5.6 at that focal range keeps the entire face in focus and still gives you a nice soft out of focus background. This being said, I have recently picked up the Canon 24-105mm f4 L series lens (which in only about a grand brand new) and find it is a nice "utility lens" for the money and typically my lens of choice for interviews unless we have the budget to rent better glass.
