Sorry if I am not doing this right but I'm not clear on the process for reporting issues.
Just thought I'd report a behavior I am seeing on my 70D when running ML (2016Apr23.70D111A). With ML installed and running, if I take a shot and then review it on the LCD, then press the MAGNIFY button, the image zooms in fully, rather than just magnifying to the next level. In order to zoom in only partially I have to hit the magnify button which zooms in full, then zoom out with the REDUCE button.
If I power down the camera, insert a non-ML SD card and then power the camera back up, the MAGNIFY and REDUCE buttons function normally.
If I power down the camera, re-insert the ML SD card and then power the camera back up, the MAGNIFY and REDUCE buttons again function improperly.
Hope this helps
