I really love this camera. But I already owned the Alpha series, should I stay on in A mount or switch to E mount. Tough question. By the way, do enjoy the Sony official video below.

Some of the features of NEX-7:
All-new 24MP APS-C CMOS sensor
ISO 100-16000
Built-in 2.4M dot OLED EVF with eye sensor
Electronic first-curtain shutter (cuts response time from 100ms to 20ms)
‘AVCHD Progressive’ 1080p60 HD movie recording with built-in stereo mic
Tilting rear screen
Three-dial user interface
Built in flash and Alpha hotshoe (Yeah, I can reuse back my Sony Alpha Flashes)
Infra-red remote control receiver
Microphone input socket
