Why can't my camera press the shutter after installation?

This is a full manual focus lens, no electric contacts, your camera will not detect the lens when mounted, switch camera to M mode and then you can press the shutter and take photo.

Why does my picture seem to be blurry, out of focus?

Fine tune the front focusing ring to make your target in focus.

How to do if the image turns out dark?

Increase the ISO and decrease the shutter speed. If the image turns out too bright, reverse the above steps.
