The Sony E 16mm F2.8 is a wide-angle prime lens for the Sony E-mount, announced by Sony on June 11, 2010. [1] [2]
The E-mount is a lens mount designed by Sony for their NEX and ILCE series of camcorders and mirrorless cameras. The E-mount supplements Sony's A-mount, allowing the company to develop more compact imaging devices while maintaining compatibility with 35mm sensors. E-mount achieves this by:
Despite featuring the shortest focal length of any prime lens currently manufactured by Sony, the 16mm lens is infamous for its strong pincushion distortion, heavy chromatic aberration, and overall image softness. However, some of this can be digitally corrected in the camera. [3] [4]
In photography, the term "acutance" describes a subjective perception of sharpness that is related to the edge contrast of an image. Acutance is related to the amplitude of the derivative of brightness with respect to space. Due to the nature of the human visual system, an image with higher acutance appears sharper even though an increase in acutance does not increase real resolution.
The lens can also be adapted with a 12mm ultra-wide angle or a 10mm fisheye converter, which are both sold separately from the lens itself.
