The bottom line The Sony FE 14mm f/1.8 GM Ultra-Wide Prime Lens is the lightest f/1.8 ultra-wide for full-frame mirrorless at $1599. The f/1.8 maximum aperture pulls in two stops more light than the f/2.8 zoom alternatives, the XA element and three aspherical lenses crush coma and sagittal flare for clean astro star fields edge to edge, the 460g weight stays manageable on the A7 IV body for travel, the two XD linear motors drive AF that snaps without hunting in low light, and the rear filter holder accepts gel filters for landscape work where front 95mm round filters fail. The trade is the bulbous front element that blocks screw-on filters and the $1599 price that runs hot for occasional ultra-wide users.
