What is the difference between optical zoom factors 3, 4 and 5?

The differences of optical zoom multiples of 3, 4 and 5 are: different zoom focal length, different zoom range and different wide-angle shooting ability.

First, the zoom focal length is different.

1, optical zoom factor 3 times: zoom focal length 3 times of optical zoom factor is 28mm-72mm.

2. The optical zoom factor is 4 times: the zoom focal length with the optical zoom factor of 4 times is 35mm- 105mm.

3. The optical zoom magnification is 5 times: the zoom focal length of 5 times the optical zoom magnification is 35mm- 140mm.

Second, the scope of narrowing is different.

1, 3x optical zoom: 3x optical zoom can zoom objects beyond10m to 5m.

2.4 times optical zoom factor: 4 times optical zoom factor can zoom objects beyond 10 meter to 2.5 meters.

3. Optical zoom factor of 5 times: An optical zoom factor of 5 times can bring objects beyond 10 meter closer to 2 meters.

Third, wide-angle shooting ability is different.

1, 3x optical zoom: 3x optical zoom has weak wide-angle shooting ability and small shooting area.

2. The optical zoom factor is 4 times: the wide-angle shooting ability with the optical zoom factor of 4 times is average, and the shooting area is average.

3. Optical zoom factor 5: Wide-angle shooting with optical zoom factor 5 has the strongest shooting ability and the largest shooting area.
