Use Tips
Quick focusing technique
First, lock the target at a low magnification of 25 times, then gradually increase the magnification and fine tune the central focus knob
When observing moving targets, it is best to maintain a distance of 16-18mm between the eyepiece and the eye exit pupil
Scenario optimization suggestions
Bird watching: Use a medium magnification of 25-40 times, combined with a light shield to reduce glare
Shooting range: When activating the 75x magnification, ensure that the tripod is placed on a stable surface
Mobile shooting adaptation
When connecting a smartphone through an adapter ring, it is recommended to turn off digital zoom to preserve image quality

Usage Guidelines
Maintenance requirements
To clean the lens, it is necessary to first use air blowing to remove dust, and then use a dedicated lens pen to wipe it unidirectionally
Keep the desiccant inside the tube during long-term storage to avoid high temperature environments
Usage restrictions
When magnified 75 times, the field of view is only 1.8 °, and it is necessary to predict the target's movement trajectory in advance
The waterproof function is not suitable for underwater use, and the silicone grease at the interface needs to be checked annually
