Commander Optics Super 420-800mm / 1600mm (with 2X Teleconverter) f/8 Manual Telephoto Zoom Lens for Nikon F Mount DSLR Cameras + Photo Essential Accessory Kit

No matter how good autofocus is there are still times when manual focus is a better shooting option. When used in a night scenario, it gives a photographer more control over the photo, and in some cases, achieves effects that aren’t otherwise possible in autofocus mode. This high definition 420-800mm zoom telephoto lens incorporates not only computer optic designing, but also the latest optical multi-coating techniques. Manual Lenses with Long Focal Length: It is recommended to focus with live-view to achieve accurate focus. As with all long telephoto zoom lenses, a combination of sturdy camera support, substantial tripod, good technique, fast shutter speed, use of remote, and mirror lock up are recommended to avoid camera shake to achieve the best results.
