R7/R10 button customization bug?

[NewJerseyGuy]

While I love the button customization flexibility of the R10 and guessing it's very similar to the R7, I think I've stumbled upon an undocumented shortcoming, which if resolved by Canon, could actually be a big help to a lot of us. It's about the focus point selector button that's also the zoom button when in the picture review mode. I set mine to Control Dial Function as I often want to switch from Focusing to Control as all my other buttons that permit customized have already been taken. And it works great until... I'm in picture review mode and want to zoom in. Nope, it doesn't work anymore. It would be so easy for the camera's software to see that I'm now in the picture review mode where the focus/control ring/dial is useless and revert the magnifier button to it's intended behavior in that mode. No? Let me know what you guys think. For anyone interested, I have AF button set to AF start; * set to Eye AF; Shutter set to meter only; Video(red button) to exposure lock; and AF/MF button set to toggle Servo/Single. I've had to hijack my ISO on the 4-way for exposure compensation which is a shame as is the fact that the lock button does nothing for my needs though I'm sure some folks get some mileage from it. Perhaps assigning short-press and long-press options for custom functions and lock respectively is something that Canon could consider implementing to empower that little guy 🙂 For those of you embarking on your customization adventure, make sure you have page 832 of the manual bookmarked and open. All said, what an amazing machine in that tiny package!

Why do you feel this behavior is a bug?  Rebel DSLRs have a similar behavior.

I'm new to the Canon world so I have no frame of reference and a quick search on the forum for button customization did not yield the ton of results that I was expecting to see and read through. It just seems so much like an oversight than a limitation. The fact that it's not documented in the manual just reinforces that assumption. Has this been discussed here before? Please point me to it if it has, I'd love to read through such a discussion.

The R10 and R7 have only been shipping for a short time.  So, you may not find much discussion about them, much less something as specific as your issue.

Here is the way I see it.  You have changed the default functionality of the button to something completely different.  I’m not sure what the button is now set to, but it really does not matter.

What matters is that you have changed and removed the default functionality.  Now you are complaining that the default functionality is gone.  It seems that only the default setting includes the dual functionality when the camera is in Playback Mode.

I’m not sure if that is a bug, or not.  You removed the default behavior.  It is what it is.

Thanks for the reply. Of course, that's all in my C1 and I still have the defaults if I switch back to one of the standard modes. Having said that, I still want my anti-lock brakes even when I'm not in D and most cars recognize the need to keep acceleration and braking isolated  😉 Fingers crossed that Canon will see this or a similar post soon...
