General

The Sony FE 50mm F/1.2 GM SEL50F12GM and the Sony FE 50mm F/1.4 GM SEL50F14GM are G Master prime lenses for the Sony E mount, so either fits the same full-frame bodies. Both cover the full-frame format. The F/1.2 GM arrived in 2021 and the F/1.4 GM followed in 2023, two years apart.

The F/1.4 GM is the lighter carry: at 516 g it saves 262 g over the 778 g F/1.2 GM. It is also more compact, at 96 mm long and 80.6 mm across, against 108 mm and 87 mm for the F/1.2 GM.

The F/1.4 GM takes 67 mm front filters while the F/1.2 GM takes 72 mm, so existing filters fit only one of them directly. Both accept front filters, so a polariser or ND stays an option on either lens.

The F/1.2 GM is the stronger choice for very low light and the shallowest depth of field, because its f/1.2 maximum aperture is wider than the f/1.4 of the newer lens. That extra width keeps shutter speeds usable for evening portraits or candlelit interiors, and it thins the plane of sharpness for isolating a subject.

The F/1.4 GM focuses slightly closer, reaching 38 cm against 40 cm for the F/1.2 GM, and offers 0.18x magnification instead of 0.17x, enough for tighter framing on flowers and detail shots. The two share the same 50 mm focal length, an 11-blade automatic diaphragm, autofocus and a manual focusing ring.

Features

Weather sealing and fluorine coating are shared strengths, so both lenses are built for outdoor use and both front elements shed dust and fingerprints more easily than uncoated glass. Neither offers in-lens image stabilisation or teleconverter support, so steady low-light shooting relies on the camera body or shutter discipline.

Construction

The F/1.2 GM uses three aspherical elements, one more than the F/1.4 GM, in a 14-element, 10-group design. The F/1.4 GM splits its 14 elements into 11 groups and adds a low-dispersion element, glass that helps reduce chromatic aberration. Both share one bi-aspherical element and internal focusing, so neither extends its barrel while focusing.

Verdict

Pick the Sony FE 50mm F/1.2 GM for dim-light portraits, indoor events and cinematic shallow-focus work. Its f/1.2 maximum aperture is the widest of the pair, a lead the newer lens cannot match.

Pick the Sony FE 50mm F/1.4 GM if you carry a camera for hours at a time. It is 262 g lighter, and its 38 cm close focus suits tighter framing of flowers and small objects. Both are weather-sealed GM primes for the same Sony E system, so the choice is maximum aperture against carrying comfort and close reach.
