Sony Camera E:64:00 — Lens Motor Fault Fix Guide

What Does This Error Mean?

E:64:00 is a lens motor fault — the focus or aperture motor inside the lens isn't responding correctly.
Most often the lens is the problem, not the body.
Power off, swap to a different lens, and test.
If E:64:00 disappears with another lens, your original lens has a failed motor — Sony lens repair (200–500 USD) or replacement.
If E:64:00 appears with any lens, the body's lens controller has the fault.

Affected Models

Sony Alpha A7 series
Sony Alpha A9 series
Sony Alpha A6000 series

Common Causes

Lens focus motor failed
Lens aperture motor stuck or jammed
Lens dropped or impacted causing internal damage
Body lens controller IC failed
Aftermarket adapter blocking motor signals

How to Fix It

Power off and remove the lens.

Standard reset: turn off, remove battery, remove lens.
Wait 30 seconds.
This clears any latched controller state in both body and lens.
Test the lens manually.

With the lens off the camera, switch it to manual focus.
Turn the focus ring — should rotate smoothly with light resistance.
If it grinds, sticks, or won't move, the focus motor mechanism is jammed.
Same test for aperture if your lens has a manual aperture ring.
Try a different known-good lens.

Mount a different Sony E-mount lens.
Power on and try focusing.
If E:64:00 doesn't appear, your original lens has a failed motor.
If E:64:00 appears with any lens, the body has the fault and needs Sony service.
Remove any adapters.

If using EF-to-E or other lens adapters, remove the adapter and try the body with a native E-mount lens.
Cheap adapters can block motor control signals.
If E:64:00 only appears with adapter+lens, the adapter is the issue.
Use Sigma MC-11 or Canon's official adapters for reliability.
Send to Sony service.

Lens motor repair: 200–500 USD typical for prime lenses, more for telephotos.

Frequently Asked Questions

Will E:64:00 always block shooting?

Mostly yes — without working lens motor, autofocus and auto-aperture don't work.
Some bodies allow shooting with manual focus and manual aperture ring (if the lens has one).
For lenses without manual aperture rings, you're stuck.
Plan for repair to restore normal use.

Can a drop cause E:64:00?

Yes — direct impact on the lens can shift focus motor components out of alignment or break internal connectors.
If E:64:00 appeared right after a drop, that's almost certainly the cause.
Service the lens — running a drop-damaged lens often makes things worse over time.
