Why is my image blurry or out of focus?
Quick answer
Blurry images can be fixed by adjusting the diopter, focusing the lens, performing image calibration, selecting the right amplification and color modes, and fine-tuning contrast and brightness.
If your image is blurry or out of focus, try the following steps to adjust and improve the clarity:
- Adjust the diopter:
Use the diopter adjustment on the eyepiece to make the icons on the display and status bar appear sharp. - Focus the lens:
Adjust the lens focus to clearly view your target. Remember, re-focusing may be necessary as the distance to the object changes. - Perform image calibration:
Calibrate the image using either manual mode (with the lens cover closed) or automatic mode. - Choose the right amplification level:
Select the most suitable level—Normal, High, or Ultra—based on the observation conditions. - Explore color modes:
Cycle through the different color modes to find the one that works best for your environment. - Adjust contrast and brightness:
Manually adjust these settings, ensuring they remain at similar levels. A large difference between contrast and brightness can negatively affect image quality.
