TABLE 1 Change in position of front and rear lens groups locked
Carry out stability test to the frock of the change objective motor that this embodiment provided. Since the stability test is prior art, it is not described herein in detail. The experimental data are shown in table 2 below:
TABLE 2 measured impact resistance test data of mechanism
The stability test results show that:
1) after 5G impact: maximum change in sensor readings of 0.01% (about 0.12 μm);
2) after 7G impact: maximum change in sensor readings of 0.01% (about 0.12 μm);
