Not for spying or anything but a nice SLR type optical zoom would be awesome! Safer flying in those hard to reach areas..... I'm sure those huge 13'' blades could handle it with ease.....
I think it's pretty much up to Sony to develop something new..... before we where waiting for Go-Pro & now we wait for Sony.... it's just trading in 1 dictatorship for another.... maybe a new release of some new hyper camera will come about in the future.... but until then it' the 4K battle between the 2 turds.
