We recommend time-lapse shooting, using a tripod or shutter cable to stabilize the image and take beautiful photos. This manual focus telephoto zoom lens is recommended for professional photographers and is suitable for DSLR cameras, but not for mirrorless cameras; ・[Tips for Solving Overbright/Dark]: First, meter and focus at a long focal length, then lock the exposure. Next, change the focal length and take a picture. This method ensures proper exposure based on the initially set metering point, even when changing the focal length. If the photo is too dark, you can improve it using the following methods: 1) Change the shutter speed from 1/500 second to 1/100 second, or even slower (e.g., 1/50 second); 2) Increase the ISO sensitivity from ISO 100 to ISO 200, 400, or 800 (e.g., ISO 200, 400, 800); 3) Change position so that more external light enters the camera's image sensor through the lens; ・[Warm Tips]: 1) The lens does not support Canon EOS R, Ra, RP, R1, R3, R5, R5 mark II, R5 C, R6, R6 mark II, R7, R8, R10, R50, R100 | EOS M, M3, M5, M6, M6 mark II, M10, M50, M100, M200. 2) Not suitable for sports shooting. 3) Avoid prolonged use in windy, sandy, or dusty environments. Contact with humid air for extended periods may cause mold to grow on the lens, affecting its use. If the surrounding humidity is high, we recommend using a drying box.
