AF 45mm f/1.8 - Sony FE Fit

The Samyang AF 45mm f/1.8 FE is a compact normal-length prime lens designed for Sony E-mount full-frame mirrorless cameras, though it can also be used on APS-C models where it provides a 67.5mm equivalent focal length. The bright f/1.8 maximum aperture enables excellent performance in low-light conditions and provides strong control over depth of field for selective focus and subject isolation. The optical design features two aspherical elements and one extra-low dispersion element that work together to minimize spherical and chromatic aberrations, resulting in improved sharpness and color accuracy.

An Ultra Multi-Coating reduces flare and ghosting to achieve higher contrast in challenging lighting conditions, while the linear STM autofocus motor integrates seamlessly with Sony's AF systems for quick and precise focusing with manual override capability. The internal focusing design maintains the lens's compact profile and prevents front element rotation during use, and the rounded nine-blade diaphragm delivers smooth, pleasing bokeh quality.
