4. Focusing and Aperture

The camera's focal length and aperture have been set by technicians at the factory. If you need to refocus the camera or adjust the aperture during use, take the Mars 2H as an example (note that some camera models do not allow adjustment of focus and aperture. If the camera's focal length and brightness appear abnormal during use, please contact our technical engineers promptly). There are two rotating axes in the middle of the Mars 2H camera: the front one represents the focal length, and the back one represents the aperture. When adjusting the focus or aperture, rotate slowly while observing the image until the desired effect is achieved.
