Can binoculars choose zoom?
Yes, but it's better not to have too much variable multiple.
Zoom telescopes are very convenient and suitable for many purposes at the expense of the following indicators:
1. The price is slightly higher;
2. The structure is complex and easy to be damaged;
3. The angle of view is generally small;
4. There are many lenses with poor resolution;
5. Backlight performance is not as good as fixed multiple, the contrast will be lower.
