How can I get a replacement viewfinder attachment (loupe) for the FS700? Similarly has anyone used a different brand loupe to fit on the screen? Kinotehnik makes a viewfinder loupe that will cover a 3.5" LCD screen. It's shorter and sturdier than the Sony one. I know the Sony one can be shortened (as I shortened my old one). But if I am going to buy a new one anyway and the price is the same, it's not a bad idea to consider another brand.
