I found this Android App today DSLR Contoller https://play.google.com/store/apps/d…dslrcontroller it enables you to connect certain Canon cameras and get various levels of control over them…….as most of my gear is getting on then I was limited as to what worked as I only have one DSLR with Liveview it only costs afew pounds and all you need is a OTG cable for the nexus and a USB cable to connect to the camera.

My S70 compact ……….Nothing…………to old
My 5D…………………….Nothing ………..to old and no liveview
My EOS-M ………………Nothing………… (seems disabled by Canon)

My 40D………………….Worked a treat and the list of cameras seem to be after that date probably as this is the oldest I have that can use Liveview .

There is a list of cameras it can control on the website and the images are transferred to the nexus for review after shooting.
Supported Canon EOS models:
– Full support: 1D mk IV, 5D mk II, 5D mk III, 50D, 550D, 6D, 60D, 600D, 650D, 7D, 70D, 700D, 750D, 1100D
