Here are the key specifications:
- 17 lenses and sensors
- each sensor is 1/3.2" 8mp BSI (backside illuminated) sensor
- fully spherical view
- f/2.2 aperture
- photo resolution: 136 megapixels
- video resolution: 4k @ 30fps
Besides the ultra-high resolution, I was also surprised at the Staro's size. The sphere is only about 2 inches (5 cm) in diameter, smaller than even the Samsung Gear 360. Besides the convenience of a small size, it also means that there is a smaller distance between the lenses for less parallax stitching error.
Another feature of the Staro is that unlike most 360 cameras, it does not use fisheye lenses. This has the advantage of having more consistent sharpness across the field of view of each lens. (By contrast, the Nikon Keymission 360 and Ricoh Theta for example have noticeable drop-off in sharpness toward the edge of each lens).
The rep said it stitches the images in-camera, although that part sounds too good to be true, so it could be just a miscommunication. I will inquire further.
The Staro costs about $1,500 (slightly less than the Panono). However, the rep said they are planning to create a consumer model with a lower resolution but otherwise similar design, with a target price of $500. Here is their official webpage. Here are sample photos.
