Just an observation. We know that an iPad will connect to a Canon DSLR, eg I have CamRanger running and integrated, in clunky way, into my ML-based workflow, eg for my TS-E workflow:
- connect CamRanger (CR) via USB
- use CR to compose
- use CR to tilt and rotate the plane of sharp focus, ie CR has focus peaking and it is clearer to see focus than on the small MZ focus box in ML
- shift as required
- use ML Auto-ETTR to set the optimum shutter speed
- take picture :-o)
In other words convergence between Canon, CamRanger and Magic Lantern means a content photographer!
