Lens Not Detected
Panasonic Camera
Severity: ModerateWhat Does This Error Mean?
Lens Not Detected means the camera cannot communicate with the lens. The lens may not be fully mounted, the contacts may be dirty, or the lens is incompatible. Remove and reattach the lens firmly.
Affected Models
- Panasonic Lumix S5
- Panasonic Lumix GH6
- Panasonic Lumix G9
- All Panasonic interchangeable-lens cameras
Common Causes
- Lens not fully seated — twist until it clicks
- Dirty lens contacts
- Incompatible lens (wrong mount)
- Lens adapter not making proper contact
- Lens electronic failure
How to Fix It
-
Remove and reattach the lens — twist until it clicks.
Make sure the alignment dots match and the lens locks into place.
-
Clean the gold lens contacts.
Use a microfiber cloth or pencil eraser on the contacts. Clean both the lens and camera body contacts.
-
Check lens mount compatibility.
Lumix S: L-mount lenses (or adapted via adapter). Lumix G: Micro Four Thirds lenses. Do not mix without the correct adapter.
-
If using an adapter: clean the adapter contacts too.
Adapters add another set of contacts between lens and body. All three connection points must be clean.
Frequently Asked Questions
Can I use Canon lenses on Panasonic?
With an adapter (like Sigma MC-21 for L-mount), you can use some Canon EF lenses. Autofocus may be slower than native lenses.
What is L-mount?
L-mount is the lens mount shared by Panasonic Lumix S, Leica, and Sigma. Any L-mount lens works on any L-mount body.
