Overheating During Video Recording

One of the primary complaints with the Canon R5 has always been overheating, especially when shooting 8K videos. Initially, approximately 20% of Canon R5 users reported experiencing this issue. However, this is primarily a past problem, as Canon has released firmware several times that address the issue. However, there is still a chance your Canon R5 may "overheat" while shooting in 8K. Some steps you can take to solve that problem are:

Solution:

  • Reduce the recording resolution or frame rate.

  • Limit continuous shooting duration.

  • Switch off the camera when not in use to allow it to cool down.

  • Use an external fan to keep the camera cool when shooting for extended periods.

Battery Drain

15% of users report rapid battery drain with the R5. The R5 is a power hungry camera with features like the high res electronic viewfinder, in body image stabilization, continuous autofocus, Wi-Fi and Bluetooth and more. Each of these features uses up power. When used extensively or at the same time they can really drain the battery.

(Example: You use Wi-Fi or Bluetooth to transfer images to your phone to share. But that uses up battery too.)

Solution:

There are several measures you can take to mitigate battery drain on your Canon R5:

  • Monitor Brightness: One of the simplest ways to save battery life is to lower the monitor's monitor's brightness. You can adjust this in the camera settings, but remember that the screen might be harder to view in bright conditions.

  • Turn off Wi-Fi/Bluetooth: When you're not transferring files or using your phone as a remote viewfinder, consider switching off Wi-Fi and Bluetooth.

  • Limit Use of Power-Intensive Features: If you plan to shoot for an extended period, consider how often you use power-intensive features like image stabilization, continuous autofocus, or high frame rate video recording. While incredibly useful, these features can significantly reduce battery life when used consistently.

  • Extra Batteries or Battery Grip: For extended shooting sessions, invest in additional batteries or a battery grip that can hold two instead of one. This effectively doubles your shooting time without the need for recharging.

  • Firmware Updates: Canon periodically releases firmware updates for its cameras, which can include improvements and optimizations that enhance battery performance. Always make sure your camera's firmware is up-to-date.

By implementing these strategies, you can significantly improve the battery life of your Canon R5, allowing you to focus more on capturing great shots and less on preserving battery life.

Autofocus Issues

About 12% of users report problems with the camera's autofocus system, which can sometimes struggle to lock onto subjects, particularly in low-light situations. These challenges range from slower focusing speed to occasional struggles with subject tracking, especially in low-light conditions.

Achieving sharp focus is fundamental to capturing high-quality images, and understanding how to use and adjust your camera's autofocus settings is crucial. Here are three general tips for getting Sharp Focus:

Tips For Focus in General

  1. Use the Right AF Mode: The Canon R5 has several autofocus modes suitable for different situations. Single-point AF is excellent for static subjects, while Zone AF or Large Zone AF can be better for subjects that move unpredictably. Experiment and understand each mode to choose the right one for your scenario.

  2. Control Aperture: A wider aperture (lower f-number) creates a shallow depth of field, making the focus more critical. On the other hand, a narrower aperture (higher f-number) gives a larger depth of field, offering more leeway with focusing.

  3. Stabilize Your Camera: Even the slightest camera movement can cause your image to lose sharpness. Use a tripod or image stabilization (either in the lens or in-body) to ensure the camera remains steady, especially in low light conditions or when using slower shutter speeds.

Solution

  1. Increase ISO in Low Light: Boosting the ISO can better help the camera's autofocus system detect subjects in low light. However, higher ISO settings can also introduce more noise into your images.

  2. Customize AF Settings: The Canon R5 has customizable AF settings that you can tweak according to your needs. For instance, you can adjust the tracking sensitivity to match your subject's movement speed or change the AF point auto-switching speed when shooting in Zone AF or Large Zone AF. The Canon R5 provides a wealth of customizable autofocus settings that allow you to adjust the behavior of the AF system to suit your specific needs. Here are some key settings that you can tweak to optimize your autofocus performance:

    1. AF Method: This lets you choose how the AF points are used. Options include Spot AF (small point for precision focusing), 1-point AF (single point), Expand AF area (surround points aid the central point), Zone AF (group of points), Large Zone AF (bigger group of points), and Auto Selection AF (camera chooses AF point).

    2. Subject to detection: This setting can significantly impact your focusing results. For example, if you're shooting portraits, choose ''People'' to enable the camera to detect faces and eyes. If photographing birds or animals, select ''Animals'' to utilize the animal detection feature.

    3. AF Case Settings: The R5 has case settings (Case 1 to Case 4) that control the tracking sensitivity, acceleration/deceleration tracking, and AF point auto-switching. These settings are invaluable when shooting subjects with unpredictable movements, like sports or wildlife.

    4. Lens electronic MF: This setting lets you adjust the focus manually after the camera has focused in the One-Shot AF mode, offering an added level of precision. For instance, for a subject that moves erratically, you could use Case 2, which adjusts the tracking sensitivity to stop the AF from accidentally jumping to a new subject. For a subject that changes speed abruptly, Case 3 modifies the acceleration/deceleration tracking to help maintain focus on the subject.

    5. Regularly Update Firmware: Canon often provides autofocus improvements in their firmware updates. Always ensure your camera's firmware is up-to-date to benefit from these enhancements.

By following these suggestions and understanding the ins and outs of your camera's autofocus system, you can alleviate many common autofocus issues and capture sharper, more dynamic images with your Canon R5.

Slow Write Speeds

Approximately 10% of Canon R5 users have reported issues with slow write speeds, mainly when shooting in burst mode or recording high-resolution video. Slow write speeds cause the camera to stop recording sometimes with little to no obvious notice.

Solution:

  • Use CFexpress cards instead of SD cards for faster write speeds.

  • Limit the use of burst mode.

  • Consider reducing the image size or video resolution if write speeds continue to hamper your shooting.

Firmware Issues

Firmware issues can happen with complex devices like the R5 and 8% of users have reported them. They can manifest in many ways, system glitches, lags, crashes and even unexpected shutdowns. For example one issue has been the camera freezing while in use and needing a restart. Another common firmware issue has been not being able to connect or maintain a connection with the Canon app.

These firmware issues can be frustrating because they interrupt your workflow and you might miss the shot. But the good news is Canon addresses these bugs and issues through firmware updates and continually improves the R5.

Solution:

  • Regularly check Canon's official website for firmware updates and install them as soon as they are available.

  • Before updating, ensure your battery is fully charged to prevent disruptions.

  • Follow the instructions provided by Canon carefully when updating your firmware.
