Has anyone gone on a similar journey searching for a good android phone app?
Well now you've got me started looking again... ;-)
The first hurdle to evaluating different apps is getting to grips with Canon's WiFi options. Although my 5Div came with a 180 page manual
just for the WiFi, a fair bit of the functionality isn't really explained well and some aspects are rather unintuitive.
I would expect to just connect to the camera with the phone, then fire up any app and connect. However it seems you need to configure a new 'connection set' for each app with a different WiFi network, so no easy flipping between apps.
Next problem is that there are only three connection sets possible.
Once you start to look at the apps available, some seem very patchily supported and developed.
I've now tried a few more and the only recently developed product is qDslrDasboard, which seems the best alternative to Canon Connect so far and has the extras the Canon app lacks eg timelapse, focus stacking and more bracketing options.
I can't understand why Canon don't sell firmware updates, or premium apps, for additional functionality. Sony seem to have managed this.
