Manual focus telephoto zoom lens is recommended for professional photographers, suitable for digital SLR cameras, not for mirrorless cameras;
Resolving Overbright/dark Tips: You can start by focusing and metering at a position determined as the exposure reference using a long focal length, then locking the exposure and then changing the focal length to take the picture. If the photo is too dark, you can remedy the situation by the following methods:1) Reducing the shutter speed from 1/500 sec. to 1/100 sec, or slower, such as 1/50 sec, 2) Increasing the ISO value from ISO 100 to ISO 200/400/800, etc, 3) Switching the position so that more ambient light enters the camera’s imaging sensor through the lens;
