The Exmor R camera sensor is one of the key highlights for the upcoming Sony Ericsson Xperia arc. The back-illuminated CMOS sensor allows light directed onto the silicon from behind, which leads to enhanced low-light shooting.
Sogi.com took the Xperia arc out on the streets of Taiwan to put this to the test. They managed to test the camera on both automatic and night settings and the results look pretty good. Check them out below.
