Sony Announces New 20mm f/2.8 NEX System Pancake Lens

Lenses Mirrorless News Sony

Sony has announced a new, compact prime lens for their NEX mirrorless camera system. The new E-mount 20mm f/2.8 pancake lens has a focal length equivalent to 30mm on a 35mm / full-frame camera. That’s a conservative wide-angle focal length – very close to the traditional 35mm focal length preferred by photojournalists and street photographers. The large f/2.8 aperture is good for shallow depth-of-field photos as well as low light photography. The 20mm f/2.8 lens’s compact pancake design helps make the Sony’s NEX camera system even smaller. The new 20mm lens is almost exactly the same size as the E-mount 16mm f/2.8, so there are now two ultra-compact prime lenses available for photographers who want a small, light and inconspicuous Sony NEX camera kit.
