The 7artisans Photoelectric Sony E-mount 85mm f/1.8 AF Lens is a lightweight and compact prime lens tailored for full-frame mirrorless and DSLR cameras. The 85mm focal length is particularly advantageous for portrait photography, as it slightly compresses the background, ensuring that the subject is highlighted within the frame. This lens incorporates two extra-low dispersion elements in its optical design to significantly reduce color fringing and chromatic aberrations. Furthermore, the 85mm f/1.8 features swift and accurate autofocus, complemented by a customizable function button for added convenience.
