Nikkor adapter for NEX-6
I have the following Nikkor lenses:
Nikon 18mm - 55mm f/3.5-5.6G AF-S DX Lens
Nikon AF-S DX VR Zoom-Nikkor 55-200mm f/4-5.6G IF-ED Lens
Nikon AF-S DX NIKKOR 35mm f/1.8G DSLR Lens
Of all the adapters that would work with these lenses and allow me to change aperture which adapter is..
(a) the most compact
(b) the cheapest
(c) the most functional in terms of speed, AF, etc.
