[420-800mm Manual Lens] The 420-800mm lens is a fully manual lens with no electronic contacts or autofocus functionality, so you must perform all manual operations before shooting. The procedure is as follows: 1) Attach the 420-800mm RF lens to the camera. 2) Find "Lensless Release" in the menu and set it to "On." 3) You will need to perform manual focus and adjust the ISO and shutter speed. (Aperture can be adjusted using the lens alone.)
[Adjusting the lens focal length/focus ring] 1) Release the LOCK-OPEN/ZOOM LOCK manual on the lens. 2) Adjust to the desired focal length (adjustable from 420-800mm). After adjustment, lock the focal length. 3) On the front of the lens, slowly turn the focus ring until the subject you want to focus on appears clear and sharp. 4) Adjust the ISO sensitivity and shutter speed according to your shooting needs.

[Note: Image Stabilization] This 420-800mm telephoto lens is a manual lens with no electronic contacts and no 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. If you have any questions, please feel free to contact us.
[Tips for solving 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 you change 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;
