the wifi option in this camera isnt just meant for just uploading pics to the web.. much like the gopro helmet cams, you can completely control the camera from a remote or from your smart phone. you can set and control every aspect of the camera from it. It could be an incredibly powerful feature if Canon ever opened up the SDK (software development kit) to software developers. If they were to ever do that, a developer could write an application for a computer or smart phone that could completely control the camera and add new modes of shooting or different functionality. This is just the start i hope.
This is actually one of the major reasons I want this camera over the 5D2. I often shoot things at odd angles or locations, and being able to control the camera remotely would be awesome. Also I carry around a iPad most of the time, and being able to review photos quickly on that without any cables, adapters, etc, would also be a fun feature to have. I process RAW before I upload anything, but still for checking the images it would be good.
From a consumer point of view, I could see this being the ultimate self-portrait camera. Using a phone to get your framing and focus right while away from the camera would be awesome.
From a pro point of view, being able to wireless transfer images to a computer in studio would also be handy.
I would love it if they would release the API, or if someone could reverse engineer the API. I could see doing some really cool things with that.
Is WiFi a need to have feature? I actually don't think so, but it could sure be a nice to have feature.
Excuse my ignorance here guys, but my understanding of a wifi camera is that it is WIFI enabled
i.e. can connect to a wifi network
So all the features of wireless control,viewing on ipad instantly,and writing to laptop, are all only available if all items are on the same wifi network i.e. at home !
if you're in the field,so to speak, they won't be on wifi....
it's not like bluetooth where one item can communicate with another
or am i missing something.......?
