Lytro's innovative camera eschewed the megapixel wars and instead featured a new, focus-everywhere sensor technology. The light-field sensor in the Lytro is the only one of its kind, and as one of the few truly new technologies released in 2012, it's one of Gizmodo's most important gadgets of the year. Plus, they're really fun to play around with.

But being on the bleeding edge is expensive, and we didn't expect to see any sales on Lytro for a while. But until tomorrow, with the coupon code 50SECRET, you can save $50 on any Lytro on Amazon. That brings the cost of the 8GB model down to $350 and and the 16GB down to $450. That's the first discount for a unique camera that continues to improve through software.
