The Xperia Z and Xperia ZL are priced at Rs 38,990 and Rs 36,990, respectively. Both phones will go on sale in India from March 12.
The Sony Xperia Z has a 5-inch full HD 1080p Reality Display, and is powered by a Snapdragon S4 Pro quad-core processor.
Despite its slim 7.9 mm body, Xperia Z is said to be durable with tempered glass and anti-shatter film on the front and back.
According to Sony, the Xperia Z also includes Battery Stamina Mode that is said to improve the standby time by four times or more by automatically shutting down battery-draining apps whenever the screen is off and starting them up again when the screen is back on.
Both phones are water and dust resistant.
