Lytro introduced the second generation Plenoptic Camera.
Lytro company, founded by a native of Stanford University, Ren Ng, is engaged in the commercialization of plenoptic photography, or photography of a light field, when the matrix using the microlens system captures not a flat picture, but full information about the light field of the subject - focusing such images already after the shooting, and the frames obtained by such a camera allow you to get a stereo image. A very detailed and great article about the principle of operation of such a camera was published by Antelle habrauzer . The first Lytro camera was more like a funny toy than a serious camera, and the quality of the pictures was not too high - when rendering into a plain flat image, the resolution was only about a megapixel.
The second generation camera, called Lytro Illym , is already much more like a real camera, both in appearance and in characteristics. The diagonal of the sensor has been increased from 1/3 "to 1", the resolution of the images is 40 megalouch (in these units the resolution of the plenoptic cameras is measured) against 11 in the first Lytro. Flat prints from Lytro Illym images can now have a resolution of around 4 megapixels, and the focusing accuracy has increased proportionally. Most of the camera takes a zoom lens with an equivalent focal length of 30-250 mm and a constant aperture of F2. The camera has a rotating 4-inch viewfinder with a resolution of 800x480 pixels. Her price - 1600 dollars. First deliveries are expected in July.
The camera weighs a little less than a kilogram and has dimensions of 86x145x166 mm. The minimum shutter speed is 1/4000 seconds, there is the possibility of macro photography. The lens consists of 13 optical elements. According to Lytro CEO Jason Rosenthal, the camera’s unique plenoptic sensor not only allows you to focus shots after shooting and get a three-dimensional image, but also makes it easier to correct lens aberrations using the built-in software.

Theoretically, light field cameras can have significant advantages over conventional ones. In addition to the already mentioned post-focus and stereo images, they can work much faster than usual, since they do not need to spend time on focusing. Also the ability to refocus reduces problems with a low depth of field with the maximum open aperture, which can be beneficial in poor light. In general, the creators of the camera Lytro believe that plenoptic cameras can potentially make the same revolution that digital ones have made.
