[Fully Manual Telephoto Lens]: This 420-800mm telephoto lens requires no adapter ring and installs in just 2 seconds. After attaching the lens, you'll need to use your DSLR camera for full manual focusing: 1. Set it to M mode. 2. Twist the lens's focus ring to focus, and adjust the ISO and shutter speed. (The lens aperture is not adjustable and varies with focal length.) Using a manual lens gives you complete creative control over your images, offering unparalleled creative expression and versatility.

[Note: Image Stabilization]: This 420-800mm telephoto lens is a manual lens with no electronic contacts, so it does not have autofocus or image stabilization. Therefore, even slight camera shake can dramatically affect image quality. For time-lapse photography, we recommend using a tripod or shutter cable to stabilize the image and capture beautiful photos. This manual focus telephoto zoom lens is recommended for professional photographers and is suitable for DSLR cameras, not mirrorless cameras.
[Tips for Resolving Overbright/Dark Images]: First, meter and focus at a long focal length, then lock the exposure. Then, change the focal length and take the photo. This method ensures proper exposure based on the metering point you initially set, even when changing the focal length. If the photo is too dark, you can improve it by: 1) changing the shutter speed from 1/500 second to 1/100 second or even slower (e.g., 1/50 second); 2) increasing the ISO sensitivity from ISO 100 to ISO 200, 400, or 800 (e.g., ISO 200, 400, 800); 3) changing the position of the lens to allow more ambient light to reach the camera's image sensor.
[Warm Tips]: 1) This lens is not compatible with Canon EOS R, Ra, RP, R1, R3, R5, R5 Mark II, R5 C, R6, R6 Mark II, R7, R8, R10, R50, and R100; EOS M, M3, M5, M6, M6 Mark II, M10, M50, M100, and M200. 2) It is not suitable for sports photography. 3) Avoid prolonged use in windy, sandy, or dusty environments. Prolonged exposure to humid air may cause mold to form on the lens, affecting its use. We recommend using a drying box if the ambient humidity is high.
