How to connect a 5D III (hardwired) to a iPad 4 Retina?

[mkg]

I am trying to connect my Canon 5D III to my iPad 4 Retina so I can review photos as I shoot. I want a wired connection.  I have the correct cables. One end is connected to my camera, the other is connected to my iPad. This is as far as I got. The camera will not fire. I'm looking for a detailed description of what I need to do. Help. Bob

So far this is not a really good way to view your photos.  A Macbook or laptop is way better.  But it can be done.  There is/are apps availble for iPad and andriod.  There are camera controlers too.  You just need to find them and buy one.   They are not free.

I have it working, but my canon 5D III keeps switching to BUSY. So, I turn the camera off and then on.  I can take a few pictures, then it goes BUSY again. REGARLESS OF HOW LONG I WAIT IT WILL NOT WORK UNTIL I TURN IT OFF THEN ON.

Sounds like the problem is on the computer's side. Evidently it's not reliably informing the camera that it has completed its downloads. How do I know it's not the camera's fault? I don't, but in cases like this, the smarter device (here, the computer) has more opportunity to get it wrong. Presumably you didn't program the camera to talk to the computer; you programmed the computer to talk to the camera. When you power cycle the camera, it of course forgets that it was waiting for a transmission to complete.

It is a sloppy technology right now.  Go to a laptop.

The best way is with a CamRanger.  It's reliable, doesn't require any 'hacking', and is wireless to boot.  But it requires additional hardware and isn't cheap.

I know they got DSLR controller to work with iPad if you jailbreak it, but I don't know if they've updated it for the iPad 4 yet.  Or if "they" have even jailbroken the 4 yet. 

I didn't think you could do it hardwired, via OTG cable, without jailbreaking it.  Has that changed?  I don't follow Apple too closely, and this is actually why.  If you're willing to jailbreak it I have no doubt it'll work.  I'm sure there are forums out there that would have far more information on this than here.  I use XDA forum for Android, but I don't believe they do iPad.
