The cryptic abbreviation is not important - whats important is that MEMS cameras can focus 7 times faster than current cameras and take multiple images extremely fast. Those extremely quick capture times will allow for a quick succession of shots, and if the object is not moving fast, you'd be able to shoot first and focus later, like on a Lytro camera. Be it daylight or night time, a MEMS camera locks focus in a fraction of a second and multiple times faster than current cameras. The Nexus 5 will likely be the handset that brings the technology to the mainstream.
The secret is hidden in Nexus 5 logs where we see a mention of some component referred to as imx179. Doesnt ring a bell, does it? Google will quickly reveal however that such a component exists and it is the MEMS camera we just told you about, manufactured by Digital Optics. Altogether, we have the following details about the Nexus 5 camera:
- 8-megapixel unit that is not backside illuminated (not BSI)
- f/2.4 aperture
- sensor size of 1/3.2 (a bit smaller than top shelf smartphones)
