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!
