Focus On The Lytro: A Visual Tour
Alternatively, you can activate the camera simply by pressing the shutter button, which is integrated into the top of the rubber grip. You'll be amazed at how fast Lytro is--there is virtually no lag after pressing the shutter button, and it's ready to take the next photo after a quick preview of the image just recorded.
The top of the camera is also where you'll find the camera's unusual zoom control: a row of touch-sensitive raised bumps. To zoom in, you run a finger across the bumps left to right; to zoom out, you swipe right to left. The Lytro keeps the last zoom level active between uses, which might trip up some users. The touchscreen displays a small visual indicator for the zoom level but it's easy to miss; some users will no doubt turn the camera on and accidentally take zoomed photos. We've photographically enhanced the shutter button and zoom slider to make them easier to see here.
