why no servo zoom lenses for 5D or GH4 ?
 

why? the GH4 can servo via remote, problem is that there is no servo zoom wide to tele (and it will NEVER be one, in my opinion). Same for the 5DIII . why? maybe because of of some sort of agreement between lens manufacturers and cameras to protect the sales of the new camcorders for 7x the price? If not agreed and calculated then why? There most be a reason, no?
