According to Moment, "Most existing mobile and iPhone accessory lenses are OK in the center of the frame but degrade quickly towards the edge of the frame. They also exhibit significant chromatic aberration and in most cases, significant geometric distortion."
Moment says that the glass type and larger size of its lenses help to to minimize distortion and chromatic aberration (the effect of colored fringes appearing on objects within a photo), as well as improving the quality of images from the center to the edge of the frame. Its aim, it says, is "to maximize image quality, while not degrading the resolution of the native camera."
Lenses will be produced to work with iPhones, iPads and Galaxy phones, with two types of lens produced to begin – wide and tele. Whilst the lenses are fairly similar in design, the wide model will feature a lens hood on its front to protect against scratches and sunlight.
The wide lenses will have a magnification ratio of .63x, TV distortion of less than 0.5 percent and resolutions of 300 LP/mm (axis) and 250 LP/mm (corner). The tele lenses will have a magnification ratio of 2.0x, TV distortion of less than 0.25 percent and resolutions of 300 LP/mm (axis) and 150 LP/mm (corner).
Moment expects to start delivering lenses in June. Watch the video below to find out more about the story behind the product.
