De K|Lens, een light field-lens met 3D-beeldinformatie

This article was translated from Dutch with the help of AI. Read the original.

In 2011 werd er een light field-camera aangekondigd: de Lytro. This made it possible to choose your focus point afterwards, because the direction of the light was also stored.

The Lytro never became a success. But the concept did not die with Lytro. K|Lens brings the principle to your own camera.

The Lytro was an odd one out. The camera was nothing more than a rectangular box. It had a low resolution and you could not do much with the images without the special software.

Now there is the K-lens, a project on the infamous Kickstarter platform. It promises to bring a light field lens to the market in 2022. So it is not a light field camera, like the Lytro, but a lens that you can get for Nikon F and Canon EF mounts.

The lens can capture different directions of light thanks to an internal mirror housing. Cleverly positioned mirrors generate nine images that show the subject from a slightly different angle. This combined image is then projected onto the sensor.

The image projected by the K-lens looks a bit like a kaleidoscope, hence the K in the name. The mirror housing that splits the image makes this lens large and heavy. Although it has a focal length of just 80mm, it looks more like a 400mm telephoto lens.

The image result has to be converted into a depth profile using the manufacturer's SeeDeep software. This depth profile can be read by Photoshop.

It is also possible to combine the nine images into a super-resolution image. Do bear in mind that initially you only have an image with just 1/9 of your sensor's resolution.

The target audience for this lens is probably very small. The price is also very high, almost 3,600 euros, although you get a 45 per cent discount when pre-ordering. For now it is available in Nikon F and Canon EF mounts, but it will also be made for other mounts on request.
