Through proprietary Sony Translucent Mirror Technology™ and subject size detection, Lock-on AF continuously adjusts target frame size, based on various subject characteristics and dramatically increases the in-focus rate. Lock-on AF combines with your selected AF area mode to instantly lock on your subject and take advantage of highly accurate, Full-time Continuous AF.
ou can now capture every scene beautifully with fine details and rich tonal gradations, thanks to Sony's proprietary Exmor™ APS HD CMOS sensor. Its large sensor size delivers high sensitivity, attractive defocusing effects, and low noise in various situations including dimly lit environments.
Framing, focusing and real-time preview of exposure adjustments are much easier with the OLED Tru-Finder™ electronic viewfinder. All thanks to the Translucent Mirror Technology™ that enables you to accurately monitor the results of your settings by faithfully displaying details exactly as they appear.
