1. When the lens is opened to the highest point with slight force, one of the lens levers will follow.

2. The one circled in the figure is the spring bar, and the other side will spring accordingly.

3. Push the button upward slightly (remember not to push too hard), and your fingers will feel pushed away.

4. Push it to the specified position, and the other side is the same. Push the pull rod upward slightly.

5. At this time, the lens pull rods on both sides have been pushed to the position where the lens can be removed.

6. Then put down the lens levers on both sides. We normally turn off the camera. You can see that the lens lever will pop up again, which means that our lens has been correctly installed.
