[Be careful with image stabilization]: This 420-800mm telephoto lens is a manual lens without electronic contacts and does not have autofocus or image stabilization functions, so slight camera shake can have a dramatic effect on image quality. I have something to give. We recommend time-lapse photography, using a tripod or shutter cable to stabilize the image and take beautiful photos. Manual focus telephoto zoom lens is recommended for professional photographers, suitable for digital SLR cameras, not suitable for mirrorless cameras;
[Tips for solving overbright/darkness]: First, meter and focus with a long focal point, then lock the exposure. Then change the focal length and take the photo. This method allows you to change the focal length and still ensure proper exposure based on the metering point you originally set. If the photo is too dark, you can improve it by: 1) changing the shutter speed from 1/500s to 1/100s or even slower (e.g. 1/50s); 2) ) Change the ISO sensitivity from ISO 100 to ISO 200, 400, or 800 (e.g. ISO 200, 400, 800); 3) Change the position so that more outside light enters the camera's image sensor through the lens;
