Troubleshooting
If you have a problem with your camera, refer to this section. Consult your dealer or a Canon Service Center if
the problem persists.
Power source
The camera will not turn on or it turns off by itself.
- The battery pack is depleted. Replace or charge the battery pack.
- Remove the battery pack and reattach it correctly.
Shortly after turning it on, the camera turns off on its own.
- You are using a battery pack that is not compatible for use with this camera. Use a recommended battery pack
(A 234).
Cannot charge the battery pack.
- The temperature of the battery pack is outside the charging range. If the battery pack's temperature is below 0 °C
(32 °F), warm it before charging it; if it is above 40 °C (104 °F), let the battery pack cool down before charging it.
- Charge the battery pack in temperatures between 0 °C and 40 °C (32 °F and 104 °F).
- The battery pack is faulty. Replace the battery pack.
The battery pack is depleted extremely quickly even at normal temperatures.
B
- Check the [ System Setup] status screen (A 212) to check if the battery pack has reached the end of its battery
life. If so, buy a new battery pack.
Recording
The camera's controls are not responsive/disabled.
- The camera grip's plug may not be correctly connected to the camera's GRIP terminal. Disconnect the camera grip's
cable and then connect it again, firmly (A 41). If you changed the angle of the camera grip, make sure you did not
partially disconnect the plug by mistake.

Pressing the REC button will not start recording.
- The card is full or it already contains the maximum number of clips (999 clips). Delete some clips (A 147) or save your
recordings and initialize the card (A 46) to free some space. Alternatively, replace the card.
- The REC button that was used may be disabled. Change the current settings in the
[Camera REC Button] or [Camera Grip REC Button] setting to enable the use of the desired REC buttons.
- Power supply to the camera or the optional expansion unit has reached the level set for the power level warning
(A 205). Check the power source.
- The camera cannot record while the [Color Correction] settings in the custom picture file (A 136) are being adjusted
(except for the [Revision Level]/[Revision Phase] settings).
The point where the REC button was pressed does not match the beginning/end of the recording.
- There may be a slight interval between pressing the REC button and the actual start/end of recording. This is not a
malfunction.
The camera will not focus.
- The camera may not be able to focus on certain subjects using autofocus. Focus manually (A 82).
- When the AF mode is set to AF-boosted MF, start focusing manually until the AF frame changes to white (automatic
adjustment range).
- The lens is dirty. Clean the lens with a soft lens-cleaning cloth.
When a subject flits across in front of the lens, the image appears slightly bent.
- This is a phenomenon typical of CMOS image sensors. When a subject crosses very quickly in front of the camera, the
image may seem slightly warped. This is not a malfunction.
