Firmware Limitations with Canon R3 / R5C and EL-1 Flash – Feedback Request

Subject: Firmware Limitations with Canon R3 / R5C and EL-1 Flash – Feedback Request

Dear Canon Global Support Team,

I am a professional photographer using the Canon R3 and Canon R5C camera bodies along with the Canon EL-1 Speedlite flash. While I am generally satisfied with the system's performance, there are two recurring software limitations that significantly hinder my workflow:

1. High-Speed Sync (HSS) must be manually re-enabled each time the flash is attached or the camera is turned on.
This is disruptive in fast-paced environments. Competing systems retain the HSS setting automatically. It would be very beneficial if Canon firmware allowed this setting to persist.

2. Exposure Simulation is disabled when the flash is connected.
In many creative lighting situations, I still need to evaluate the ambient exposure before firing the flash. Disabling Exposure Simulation by default when a flash is attached restricts this ability. Other brands like Nikon, Fujifilm, and Sony allow users to override this.

Both issues appear to be software-related and should be adjustable via firmware updates. I sincerely hope Canon considers offering users more flexibility with these functions in future releases.

I remain committed to the Canon ecosystem, but improvements like these would greatly enhance usability for working professionals like myself.

Thank you for your attention to this matter.

Kind regards,

Fatih Akbörü

Greetings fatihakboru,

Sometimes things can be more efficiently resolved by discussing the issue in real time with a live agent. Given the nature of this particular issue regarding the flash unit and your EOS camera, I would recommend for you to call our technical support department by phone. Technical support can be reached at 1-800-652-2666 between Monday and Friday from 9:00 am to 6:00 pm EST.

Hi everyone,

On the Canon R3, the exposure simulation feature has never worked when a flash is attached, and unfortunately this hasn’t changed with the new 1.9 firmware update. I was hoping it would be fixed, but the option is still completely unavailable.

I have contacted Canon Turkey, Canon UK, and Canon USA regarding this issue, but I haven’t received a clear answer — only general responses. I also tried to reach Canon Japan directly but wasn’t able to.

Is anyone else experiencing the same issue? Has anyone received an official statement from Canon about this?

Thanks.
