The 4-Lens Mobile Phone Kit from SIRUI combines their black 18mm Wide-Angle Lens, red FE Fisheye Lens, and blue 10x Macro Lens.
The black 18mm Wide-Angle Lens allows users to capture more of the environment in their photos. This is especially useful for landscapes, architecture, and interior photography, as well as confined spaces and environments where the photographer may not be able to move further away from a subject when shooting it. This lens offers a 95° angle of view, 6 element in 6 groups, and less than 2% optical distortion.
The red FE Fisheye Lens captures unique and creative perspectives without vignetting using a 170° angle of view, which also renders optical distortion of 75%. This lens also features 5 elements in 4 groups and can capture macro images.
The blue 10x Macro Lens lets users capture vivid details not visible to the naked eye on flowers, insects, and other small objects. This lens offers a 10x magnification, a 75° angle of view, 3 elements in two groups, and less than 1% optical distortion.
