Vivitar 420-800mm f/8.3 Manual Telephoto Zoom Lens Bundle for Canon RF-Mount Camera with 2x Converter

420-1600mm f/8.3 HD Manual Telephoto Zoom Lens — This manual telephoto zoom from Vivitar features a front focusing ring for precise focus adjustments. If images appear underexposed, try these adjustments: lower shutter speed (for example from 1/500s to 1/100s or slower such as 1/50), increase ISO (ISO 100 up to ISO 200/400/800), use a tripod with a remote shutter release to reduce camera shake, or change your shooting position to let more environmental light reach the camera. Vivitar 2x Professional Teleconverter — The included teleconverter multiplies the focal length of your T-mount lens by 2x, effectively extending reach so you can get much closer to distant subjects. It can also be used to connect a camera to a telescope for direct prime-focus photography conveniently and easily. Vivitar T-Mount Adapter for Canon EOS R Mount Mirrorless Cameras — The T-Mount (screw mount) adapter lets you use T-mount lenses on Canon EOS R / Canon RF-mount mirrorless bodies. This Bundle from Teds Electronics Includes: Vivitar 420-800mm f/8.3 Manual Focus Telephoto Zoom Lens, Vivitar T-Mount to Canon RF-Mount Adapter, Digital 2X Converter for SLR & Digital Lenses, 12-Inch Ultra Flexible Super Steady Tripod with Ballhead, Professional Cleaning Kit.
