Sony Camera E:62:00 — Lens Electrical Fault Fix

What Does This Error Mean?

E:62:00 means the lens electrical communication failed — body and lens can't communicate, or the lens reports an internal electrical fault.
Power off, remove the lens, clean the contacts on both sides, reattach.
If E:62:00 persists with one lens but not others, the lens has damaged contacts or internal electronics issue.
If E:62:00 appears with any lens, the camera mount has the fault.

Dirty gold contacts on lens or body mount

How to Fix It

Power off and remove the lens.

Turn the camera off.
Press the lens release and rotate the lens off carefully.
Set both camera and lens on a clean surface to work on contacts.
Clean lens contacts.

On the back of the lens, look for the gold contacts (typically 8-11 contacts in a row).
Wipe with a clean dry microfiber cloth.
If discolored, use a pencil eraser very gently then wipe again.
Don't use chemicals or moisture — they leave residue that causes further issues.
Clean camera mount contacts.

Look inside the camera's lens mount.
You'll see matching gold contacts.
Wipe with a clean dry cloth.
For sticky grime, use a cotton swab very lightly dampened with isopropyl alcohol — let dry completely before mounting a lens.
Reattach and test.

Mount the lens until it clicks into place.
Power on the camera.
Take a test shot.
If E:62:00 doesn't return, contact issue was the cause and you've fixed it.
If E:62:00 returns, isolate by trying different lens.
Try a different lens.

Mount a different known-good Sony E-mount lens.
Power on and test.
If E:62:00 doesn't appear, your original lens has internal issues — Sony lens repair (200–500 USD).
If E:62:00 appears with any lens, the camera mount has a fault — Sony body service.

Frequently Asked Questions

Can a third-party lens cause E:62:00?

Yes — third-party E-mount lenses (Sigma, Tamron, Samyang) sometimes have communication compatibility issues.
Update the lens firmware via the manufacturer's USB dock if available.
If E:62:00 persists with a third-party lens but not Sony lenses, the third-party lens needs firmware update or repair.

Why does E:62:00 only appear at certain temperatures?

Marginal contacts behave differently with temperature changes.
Cold mornings or hot afternoons can expose connection issues that work fine at room temperature.
If your E:62:00 is temperature-related, the contacts have marginal connection — clean thoroughly and consider replacement if it persists.
