Which hunting flashlight should be fixed focus or zoom?

The hunting flashlight uses a zoom head to avoid the trouble of changing heads and locking the focus. Fixed-focus lenses produce good images, generally have larger apertures, constant apertures, and fast shooting speeds. They are generally high-speed lenses. Zoom heads are very convenient. They generally have floating apertures. Fixed apertures are more expensive, and large apertures are even more expensive. You can easily change the focal length to adjust the scene. What cannot be changed is that the aperture of the zoom head is too small.

The difference between zoom and fixed focus

Fixed focus can only choose a few fixed focal lengths, which are given by the camera by default, but the final image quality is better than zoom. clearer. The zoom can be within a certain range, and the range is also given by the camera. You can change the focal length arbitrarily within the range. The adjustment effect is better and the aperture is larger, but the image is not as clear as the fixed focus.

If you are a novice, buy a fixed focus, because zoom is not easy for new users to master. If the adjustment is not good, the effect will not be as good as a fixed focus. If you buy a SLR camera, you can wait until you become familiar with it before changing the lens. From now on, I will have to buy micro-focus lenses, long lenses, etc. If you want to take professional photos in the future, or you are a hardcore amateur, you will need to buy all kinds of commonly used lenses and lenses.

The difference between a fixed focus flashlight and a zoom flashlight is that the beam focus point of the zoom flashlight is adjustable. The flashlight has a battery-powered bulb and a focusing reflector. The focusing reflector is a spherical mirror made based on the principle of spherical reflection. When the luminous bead is at the focus of the sphere, the reflected light is emitted as a parallel beam. The size of the spot is theoretically The top is consistent with the lamp mouth. When the luminous beads deviate from the spherical focus, the emitted light is not parallel.
