Magnification: 2.2x teleconversion factor; mounts between the camera body and lens to extend the effective focal length (e.g., 200mm becomes 440mm).
Optics: Multi-coated (MC) Japan-manufactured optical elements; HD4 4-element construction reduces flare, ghosting, and chromatic aberration.
Mount: Precision-machined metal barrel with locking pin; available in Canon EF, Nikon F, Sony A, and other SLR/DSLR bayonet mounts.
Autofocus: AF-compatible electronic passthrough maintains autofocus and aperture control communication between the body and the lens (performance depends on the base lens's maximum aperture).
Exposure: Reduces effective aperture by approximately 2.2 stops (f/2.8 becomes ~f/5.6 equivalent); TTL metering fully supported.
Accessories: Includes padded carrying case/pouch and front/rear lens caps.
