Sony FE 50mm F1.2 GM

Reviewers rank it among the best fast standard primes on any mount. Centre resolution is excellent from f/1.2, with corners close behind by f/2. Bokeh is described as smooth with little onion-ring texture, and focus breathing is well controlled for stills and hybrid video.

The usual complaints are size and price. At 778g it is far bigger than the f/1.4 alternatives, and some testers say the FE 50mm F1.4 GM gets most of the way there for much less. Vignetting at f/1.2 is strong without correction.

Owners mostly shoot portraits, weddings and low light, and they say AF hit rate wide open is the reason they bought it over manual f/1.2 lenses. The aperture ring, de-click switch and two focus-hold buttons get regular praise from video users.

Common complaints are the weight on smaller bodies like the A7C series and the large 72mm hood. A few owners mention cat's-eye highlights toward the corners at f/1.2, which is normal for the design.
