Q: Why does my camera say “Lens not attached” or unrecognized ?
A: This is a manual lens, no electric contacts, your camera will not detect the lens when mounted, that’s why showed this notice, pls setting camera mode to M mode or “Release w/o lens” in the camera to make lens work.
Why does my picture out of focus and very blurry ?
Pls lock the”Lock-Open” ring, then rotate the focus ring on the front body of the lens until the subject is in focus , and focus with live-view to achieve accurate focus. Recommend use with a tripod and remote to keep image stable
Why picture are too dark/ too white ?
if picture is black , pls setting more slower shutter speed. such as 1/500 seconds to 1/400 seconds until image normal. if image is white, pls increase shutter speed more faster, such as 1/500 seconds to 1/800 to 1/1000 seconds until image normal.
Why it show “F00” on camera? and How to adjust the aperture value?
Manual lenses do not have an electronic contact, no auto focus, “F00” is displayed because the camera is unable to acquire aperture information. For manual lenses, the aperture value can only be adjusted with the aperture ring on the lens.
