which leads me to the next (obvious) question
Is there any advantage for Still Photographers to use cine lenses?
The fact you can afford to buy cine lenses and do buy them to take Still Photography will satisfy an underlying mental need to compensate for other inadequacies you may have. Much the same as buying large white lenses will for some.
Not wiling to spend the $ on something which is at best, marginally better. I'll take the $ and spend it on travel. I don't own any Zeiss glass, so Cine glass is definitely out of the question.
Just curious ..
