Just a quick post.
I purchased DSLR remote for the iPhone. In brief, it's a remote for certain Canon DSLRs. The setup still requires (for now) a tethered computer, to which the iPhone communicates wirelessly through a wifi network (I assume it can be ad-hoc as well as on the same network). You might wonder what the point is, since you can just use the tethered computer to take shots. And you'd have a point. It doesn't add THAT much, but it does mean you can take pictures away from your setup, such as hide in another area, or to take easier self portraits. It's also just plain 'handier'.
You can adjust basic exposure settings (shutter, aperture, iso), as well as change image quality and white balance. You can capture images to either your computer or both your computer and camera (strangely lacking an 'only camera' option). You can also set the shutter speed to bulb and use it as a timer.
You can review pictures taken (but only ones in the computer folder - perhaps why you can't capture to camera only), and even rotate to landscape and double tap an area to zoom in at 100%.
Perhaps the coolest features are a liveview mode (if your camera has it), plus also an intervalometer, allowing you to take a series of images at a particular interval, for say, time lapse shots.
All in all, it works fairly competently. There're a few quirks, but it's very simple to set up and use (requires a computer side server program, but it's all pretty much just one click, at least on the mac). It's slightly more simple to use than the EOS utility (but not as comprehensive - you can't focus for example), if only because of the touch controls.
I think it's worth the $9.99 introduction price, especially if they update and improve it with additional features, most importantly, if they release a hardware cable or dongle allowing you to tether your iPhone directly to the camera. Is it worth the $19.99 full price, though? That's a different story.
also the lense is about $350 in the US and about $500 or more in the UK etc... wtf
