The new Wide Pro provides better image quality, with more details and improved color reproduction. This new version presents almost no distortion (0.5% against 1% for the previous version). Like its predecessor, it has a focal length of 18mm and it can capture 2 times more image than the lens of your smartphone.
The new Wide Pro also ensures better compatibility with the newest smartphones, whose sensors are getting bigger and bigger. By optimizing the optical construction of their lenses, they are now able to erase the vignetting sometimes present on the edges of the image, while improving the overall quality.
