Marques Brownlee published a quick review of the Sony Xperia Pro-i smartphone, which has a 1-inch camera sensor, and he disclosed something I didn’t know. Almost all current smartphones employ plastic lens components instead of glass in their camera lenses. This information came as a surprise to me because I assumed that all camera lenses, whether from handheld cameras or smartphones, were constructed of super-polished glass.
It seemed sensible to contact Zeiss and inquire about the lens production process, as well as if Nokia smartphones use plastic lens elements. Well, Zeiss confirmed it (I’d post a screenshot of the response, but I don’t have Zeiss’ permission to do so).
Today’s smartphones, according to Zeiss, necessitate exceedingly complicated high-resolution lens elements that must be compressed into a very compact space in order to produce sharp photos. To do so, double-aspherical lens elements must be created, which is impossible to achieve using optical glass. As a result, today’s smartphone camera modules are made of molded plastic materials.
However, Sony succeeded to make its Xperia Pro-i camera the best in the smartphone world by using genuine glass lens elements. As a result, the Xperia Pro-i is a fantastic smartphone that costs up to 1800 USD.
This doesn’t surprise me, because I believe such plastic materials have excellent light diffusing capabilities, resulting in clean, clear shots.
