question

Hey so Im trying to take a photo with this lens and i cant even hear the shutter. Why wont it work for my camera.
Asked by: Isaac M.
What model camera are you using? Most likely, the camera is not recognizing that the lens is mounted on the camera, which sometimes happens with third-party lenses. Make sure the lens is on securely; it has a little play on my camera, and you can jiggle it around to see if there is a point where it works. It occurs to me, It may be mounted wrong; make sure that the white line for the distance scale is on top, and that the lens's mount is flush against the body's mount. If these ideas do not work, you will need to contact your camera's manufacturer, and maybe Opteka, and ask them.
