|Adapters galore; Nikon, Schneider-Kreuznach, Leica M & L39|
On the NEX-VG900 my Nikon 15mm rectilinear lens gives me the whole picture; can't beat that!
You can get almost any lens adapter for this camcorder on eBay. I found one for my old Retina-Curtagon 28mm Schneider-Kreuznach lens. Have you got old Leica screw-mount lenses sitting around?
UPDATE Feb. 22, 2015:
I continue to use all my manual lenses with the new Sony Alpha a7s. I utilize the same adapters I used on my NEX-7 and NEX-VG900 camcorder.
