Although it is a full-frame lens, this model is compact and weighs only 6.56 ounces. Whether on the camera or in your bag it won't be a burden, and it'll be ready whenever needed. The size and weight of this lens are an excellent match for compact α7 series bodies, providing outstanding overall portability and handling.
An updated double-gauss optical configuration with an aspherical element minimizes spherical aberration and coma for sharp, high-quality rendering throughout every frame. The double-gauss design also suppresses field curvature and distortion.
A large F1.8 maximum aperture and 7-blade circular aperture work together to create beautiful background bokeh that can make subjects stand out. Placing a sharply focused subject in front of a smoothly defocused background is an essential technique for producing deep, dimensional images.
The large F1.8 maximum aperture is an advantage when shooting night scenes or in dimly lit interiors. When used with an α series camera body that features in-body image stabilization, even greater low-light capability enables handheld capture of clear images in dark scenes without having to use excessively high ISO sensitivity.
A new DC motor drive system has been carefully designed and implemented for optimum focus precision and speed as well as quiet operation. This system provides the same smoothness for autofocus and manual focus control. Note: Focus motor sound may be recorded when shooting movies.
A metal mount adds a sophisticated feel as well as solid durability.
