An ideal match for your compact Sony full-frame format E-mount camera
One of the big advantages of having a camera that uses Sony's E-mount system is the continued addition of premium lenses from Zeiss. This legendary manufacturer, in partnership with Sony, has introduced yet another "must-have" lens optimized for full-frame cameras like the Sony A7 and A7R. This "normal" prime lens, with its superb sharpness and bright f/1.8 maximum aperture, is sure to be on a lot of photographer's wish lists.
The lens's large f/1.8 maximum aperture gathers lots of light so you can use faster shutter speeds to "freeze" moving subjects. It's also ideal for taking great-looking photos at twilight, or indoors without a flash. Nine rounded aperture blades create a nearly perfect circular opening that allows you to softly defocus background details for crisply focused subjects that pop. The 55mm focal length makes it a great choice for dramatic portraits, landscapes, and all-around picture taking.
