BENOISON 420-800mm Manual Telephoto Zoom Lens for Sony A7R A7S A7C with Multi-Layer Optical Components and Aluminum Alloy Housing, Ideal for Wildlife and Moon Photography

Experience the joy of capturing stunning details with our expertly crafted manual lenses. Each lens undergoes thorough checks to ensure optimal performance, so any issues are typically due to operational setup. Should you encounter any difficulties, our friendly team is here to assist. Please note, these manual lenses are best suited for photographers with some experience and are not ideal for beginners.

Our FULL MANUAL lenses do not have electronic contacts, meaning your camera won't detect the lens when mounted. Simply follow these steps: attach the lens with the included T-ring adapter, enable "Release without Lens" in your camera menu, and switch your mode dial to Manual (M). Focus by rotating the focus ring, and adjust the shutter speed and ISO for the perfect shot. For best results, especially with telephoto lenses, we recommend using a tripod.

Our 420-800mm f/8.3-16 Manual Telephoto Zoom Lens is compatible with an extensive range of Sony cameras, including the A7 and NEX series. Crafted with ultra-high-definition multi-layer optical components and a durable aluminum alloy housing, this lens is perfect for wildlife and moon photography enthusiasts. Elevate your photography with precision and clarity.
