Sony FE 50mm f/2.5 G Full-Frame Ultra-Compact camera lens

Ultra-compact 50mm f/2.5 G lens

The Sony FE 50mm f/2.5 G is a full-frame E-mount prime built for photographers who want G-series optical quality in the smallest possible package. Its f/2.5 maximum aperture supports low-light shooting and shallow depth of field on both full-frame and APS-C bodies. Three aspherical elements and one extra-low dispersion element deliver corner-to-corner sharpness with minimal aberrations. An aluminum exterior adds durability without bulk.

Upgrade from slower kit zooms

This prime replaces variable-aperture standard zooms that struggle indoors or at dusk. The constant f/2.5 aperture lets you hold lower ISO values and maintain consistent exposure while zooming with your feet. Dual XD linear motors and internal focus provide quick, quiet autofocus for stills and video. The jump is worth it when you need faster shutter speeds, cleaner files, or a lens that disappears in a small bag.

Sustained shooting performance

Dust and moisture resistance protects the mechanism during long sessions in humid or dusty environments. Internal focusing keeps the lens length constant, so balance on a gimbal or tripod does not shift as you rack focus. The physical aperture ring with de-click switch gives tactile, silent iris control for video work. A 13.8-inch minimum focus distance allows close-up detail without changing lenses. Rounded seven-blade diaphragm produces smooth background rendition at any aperture between f/2.5 and f/22.
