Sony Alpha 700 digital SLR replacement videoMocked-up version of new, high-end Sony camera
28 March 2011
Sony has unveiled a mock up of the replacement to its mid-to-high range Alpha 700 digital SLR.
There aren't many details surrounding the new camera, but we know it will be an SLT rather than an SLR and therefore feature an electronic viewfinder rather than an optical viewfinder.
Sony Alpha SLT cameras
SLT stands for single lens translucent, and instead of having a mirror that reflects the light passing through the lens through the optical viewfinder (as with a typical digital SLR), the Alpha 700 has a translucent imaging sensor. This lets the light through to a secondary sensor that reproduces the image electronically in the viewfinder - rather like a smaller LCD that you raise to your eye.
In an SLR the mirror moves out of the way of the sensor when the shutter is released. In theory, the lack of moving parts in an SLT makes it faster between shots. SLT technology was first introduced by Sony in last year's Alpha 33 and Alpha 55 SLT cameras.
The mocked-up Sony Alpha 700 replacement indicated that the finished product would support Full HD video shooting at 1080p resolution.
