I believe my cord came with the camera. I know the previous canon versions came with the cord, so I can't say for sure if I use an old cord or new one.

No cable was included with camera.

There is not an interface cable included, I just happened to have one from a previous camera. Sorry I don't know the part number, but it is a standard cable, just take the camera with you when you go to pick one up.

The camera can turn on very quickly. Just hit the button twice on the back of the phone, and it opens up directly with the camera app and snaps the picture.

As for video, yes it does stay in focus when one zooms in.

My camera turns on within 2 seconds. I carry it in my pocket or purse to capture interesting views. I don't use it for video, so cannot answer that question.

We have used a gorilla which attaches at the bottom to the camera, then we use the delay timer after setting up the focus we want. Works well for us.

Yes, you can.

Yes - it has wi-fi - just connect and download

The camera has built in WiFi which enables you to transfer pictures to your iPad air through the internet.

That issue is with your iMac, not the camera. Mine works great. Try rebooting your iMac.

Facebook - yes when you sync it will create a folder for the pictures it sends you can control who sees them and even add comments. Also when posting to facebook you can send single pictures or a group of them. In the book it says you can also share to Twitter, YouTube, Flickr and Google Drive. I only use it to post to faceboom so can't comment about the others
