It's the kit lens 24-105 F4.
I shot it using the Iphone app and Wifi. It's a pretty cool feature. Next time I am going to bring my Ipad so I can instantly see a good size version of the image and make adjustments remotely to the camera at the same time .
App is called "EOS Remote". It basically allows you to control shutter, aperture, focus, and ISO from a IOS/Android device. You can also review photos on the camera straight from the app and immediately after the photo is taken. It is slighty buggy, but it has a ton of potential IMO. Especially if it allowed more camera controls.
