This Adaptimax Nikon Lens with External Aperture Ring Adapter allows you to use Nikon lenses with external aperture rings on your Sony PMW-EX3 video camcorder. Sigma and Tamron lenses will also work, as long as they have external aperture rings. Lenses will have a magnification factor of 5.4X when attached to the Sony PMW-EX3. This is perfect for shooting telephoto and macro footage. You can now get images that were impossible with the stock Sony PMW-EX3 lens.
The Adaptimax adapter is CNC milled from high grade aluminum, before being anodized. It is then fitted with a brass Nikon mount that is chrome plated. This durable adapter is built to last.
