The Sigma 45mm f/2.8 Contemporary E Mount is from Sigma's Contemporary line of high-performance lenses and a part of Sigma's Global Vision series. It has been designed specifically for high megapixel full frame E mount cameras. Contemporary lenses strike a unique balance between premium quality and portability. Equipped with a high-speed stepping motor, this lens will support continuous AF when shooting video. The aperture ring has a newly developed "click feel" that is comfortable, while manual focusing has just the right amount of torque.

Special care has been taken with the expression of bokeh on this lens. Spherical aberration control is present not only for bokeh both at the front and rear of a target, but there is also softening at the periphery of intentionally-blurred images giving a three dimensional impression for enhanced isolation of your subject. This design adds a subtle swirly bokeh when shot wide open, making it reminiscent of classical lenses. When stopped down, it is extremely sharp.

The Sigma 45mm f/2.8 Contemporary E Mount is the ideal lens for portraits, but it is just wide enough to also be a wonderful street photography lens. With a high build quality that includes a dust and splash-proof mount, this lens can be taken with you anywhere.
