Sigma 90mm f/2.8 DG Contemporary Lens | Sony E, Black

The Sigma 90mm f/2.8 DG Contemporary Lens is an excellent choice for portrait photography. This compact mid-telephoto prime lens provides a selective field of view and a modest maximum aperture, making it particularly suitable for headshots, group photos, close-ups, and compressed landscapes, all while being versatile enough for daily use.

The 90mm focal length is a traditional narrow field of view that enhances portrait subjects, while the f/2.8 maximum aperture provides sufficient brightness for controlling depth of field and working with available light, all without unnecessarily increasing the lens's weight and size. Additionally, this compact 90mm lens serves as an advantageous tool for landscape photographers aiming to create more concentrated and focused compositions, allowing them to emphasize particular subjects from afar.

The Contemporary Line lens boasts a sleek and compact design, measuring around 2.5 x 2.4 inches and weighing slightly more than 10 ounces. This lightweight construction ensures it is easily portable for daily photography requirements, all while maintaining high standards in optics and speed. Its internal focusing mechanism, combined with a stepping autofocus motor, delivers quick and efficient focusing capabilities, making it ideal for both still photography and video recording.

The optical design features five SLD elements and one aspherical element, aimed at enhancing sharpness and minimizing aberrations. Additionally, it incorporates a Super Multi-Layer Coating to effectively manage flare and reflections. The rounded nine-blade diaphragm enhances the aesthetic quality of bokeh when utilizing selective focus methods. Furthermore, the construction is resistant to dust and splashes, complemented by a brass bayonet mount that ensures precision and longevity.
