The Sony FE 50mm F1.8 is the cheapest way into a fast full-frame prime for E-mount cameras. It is small and light at about 6.6 oz, with a bright f/1.8 aperture for low light and shallow depth of field. It is a simple lens: five groups, seven blades, no stabilization, and a basic DC focus motor. Reviewers like the optics for the money but complain about slow, noisy autofocus and plasticky build. It suits beginners and budget full-frame shooters; the Sony Zeiss 55mm f/1.8 and the Sony 50mm f/2.5 G are sharper and faster to focus for more money.
