For the photography aficionados in the audience, $399 is chump change compared to the kinds of glass in your collection, making Lytro a no-brainer and worthy companion of space in your camera bag. For the rest of us, though, patience is a virtue.

Right now the Lytro is essentially a one-trick pony, but let’s not forget that it’s quite the trick. Think of it this way: this camera captures multiple depths of field with one shutter click, a feat only possible previously with either a whole room filled with lenses or taking multiple versions...

After two weeks with the Lytro camera, I still can’t decide if it’s a highly refined proof-of-concept or an uneven look at the future of photography. It’s simultaneously addictive and frustrating. It’s also, as advertised, a truly unique photographic experience.

The potential of light-field photography is great — that whole “don’t have to focus” thing is maybe even more impressive than focusing after the fact — but there’s a difference between a great technology and a great product.

The Lytro Light Field Camera rethinks photography with its unique hardware and fascinating image output. But if you're not a gadget-loving, Mac-owning early adopter, steer clear until Lytro makes improvements.

For now, Lytro isn't a very practical alternative for consumers who rely on camera phones and point and shoots. Seasoned photographers might throw it in their camera bags with other gear. Despite its limits, Lytro's technology is exciting and well worth focusing on.
