- 【Setting】: This is a manual lens, NO Electronic Contacts, your camera will not detect the lens when mounted, that's why we can't press the shutter (for most Canon cameras). In this case, please find the "Release shutter w/o lens" in the menu and "Enable" it. Then it will work fine. If you still can't press the shutter, please set the camera to "MF".
- 【Manual Focus】: Please rotate the focus ring of the lens to achieve focus. Shutter speed and ISO need to be adjusted in general, so it is recommended to use it at "MF". At the same time, due to the large magnification of the telephoto lens, the slightest shaking of the hand greatly affects the quality of the picture, so pls use it with a tripod.
