Sony FE 50mm F1.4 GM

Reviewers placed it among the sharpest 50mm f/1.4 lenses available, with very good corners wide open and excellent results by f/2.8. Longitudinal colour fringing and coma are well controlled, autofocus is fast and accurate, and focus breathing is low enough for video work.

The main reservations are price against strong third-party f/1.4 fifties, some vignetting wide open, and bokeh that a few testers rated slightly less smooth than the F1.2 GM's. Build is considered excellent, though much of the barrel is engineering plastic over a metal mount.

Owners call it the sensible G Master 50: nearly as good as the F1.2 for much less weight and money. Portrait and wedding shooters praise the AF hit rate wide open and the clean rendering.

Complaints are mainly about the price, the fact that it is not much smaller than third-party alternatives, and occasional cat's-eye highlights toward the corners at f/1.4. A few users find the aperture ring's grip a little shallow.
