A little while ago, we told you about a new app for iPhones from OnOne software. They'd succeeeded in creating an app that allows you to control your camera from your iPhone. Pretty smart.

At the time, we only had info from them to go on, but now we've managed to have a play with it as well. And, in short, it's pretty impressive. 

Quite simply you need a laptop with a wifi card, a USB cable and your EOS camera. Then, with a free bit of softweare from OnOne, you can turn your laptop into a server. The sever allows the iPhone to communicate wirelessly with the laptop which, via USB, sends data to the phone, and back again. 

This means that you're not only able to trigger the camera from the phone, but you can change settings and get a Live View on the iPhone! Now, you may be thinking it'd be slow. But you'd be wrong. Ok, so it's not a fast as physically being next to the camera, but sometimes that's just not possible. It's fast enough and it seems to be a pretty robust connection. 

The only downside is that I can't find a way of focusing the camera from the iPhone as I could if I was using EOS Utility on the laptop.  But it's not a deal breaker and for the couple of £'s it costs to buy the app, it's well worth having if you have an iPhone.

Has anyone else got hold of it and had a play? What were you using it for?
