Alpha Technology

Sony redefines the DSLR with award-winning Translucent Mirror Technology in its SLT (Single-Lens Translucent) camera design. The translucent mirror is fixed in position to reduce blackout time between shots, while its innovative design also enables SLT cameras to be smaller, lighter and faster than conventional DSLR cameras.
The new 24.3-megapixel full-frame Exmor R™ image sensor used in the a (alpha)99 gives you finely detailed images from corner to corner. Combine the image sensor with Sony's interchangeable lenses and accessories and you can fill all your shots with creativity.
