ISO 102400 bug with R6?

Peter — Fri, 29 Mar 2024 18:23:39 GMT

When changing ISO with R6 I get 102400 two times. ISO 51200 > 102400 > 102400 > H.

See https://drive.google.com/file/d/1asFb5Yrsg-VHygpk-9TTAVMqL5FbJsUc/view?usp=drivesdk

This is only true if whole ISO stops are chosen or if maximum ISO is H.

Changing ISO from menu works flawless.

This is with firmware 1.8.4. I don't use ISO 102400 often so I don't know if it has been like that before.

Hi Peter,

I have just checked and found the the same on my EOS R6 which has firmware 1.8.3 installed.

ISO goes 51200 > 102400 > 102400 > H when changed with the quick control dial 2.

I also tested out the operation with a control ring mount adapter and RF lens with control ring. If I assign the control ring to change ISO either with a half-press of the shutter or directly then the ISO changes 51200 > 102400 > 102400 > H.

Thanks!

I wonder if it is the same with R5?

Where to report this to Canon?

Greetings,

R5 C, v1.0.6.1. Bug not present. ISO-H

Mine goes from 51200 > H. If I do M-Fn button then select ISO, I get the scale across the screen, I can scroll

51200 > 102400 > H. Single without duplicate 102400.

Peter, You can call support or CPS. You could probably also forward your video to Danny, Stephen or Chris.

I do not see the issue in my R6 mark II, no matter the increment setting

It seems like Canon never solved this bug and that there will be no more firmware updates for R6.
