I'm not saying I only use the INFO button. I'm saying that Canon uses it in their manuals & Canon users as a whole think of it as a button to go to for "info" on the screen.
I'm suggesting a further change to the UI of the system so we can click the INFO button for a rotation of GD info.
Of course I use GD constantly when doing shots, but right now the only way to turn it on/off is through the ML menu, not with a hard-coded button.
I know AF-ON and Expo lock both have issues, this is why I think we should reroute them to other more useful functions. Overall, we just have many many buttons on the 50D that could be rerouted and used to our benefits as ML shooters instead of browsing constantly through the huge ML menu.
Some people love timelapse, some love ETTR, some love RAW. If we restructure the hard-coded buttons so we can toggle on/off what our fave uses of ML is, then it makes our equipment much more useful. While in stock canon mode, I never take my eye off the viewfinder in my photoshoots. I don't have that luxury when in ML mode due to lack of hard-coded buttons that I'm capable of using.
The few buttons i mentioned with the ability to reroute to a slew of 12 common functions people use would be a weclomed asset by all, I would think?
