Sony FE 50mm F/2.8 Macro SEL50M28

This Sony prime is a macro lens for full-frame E-mount cameras. It handles close-up subjects such as plants, insects and small products, where fine detail matters. The 50mm focal length frames people and everyday scenes naturally too, so it can double as a walk-around lens.

Its trade-offs are the f/2.8 maximum aperture and no built-in stabilization, which matter most in low light at close working distances. Sony launched this lens in 2016, so it is an older design, but it remains in production. Those who mainly shoot static subjects will notice these gaps least. A tripod offsets the missing stabilization for tabletop work.

At 8.3 oz (236 g) and 2.8 in (71 mm) long, it is a small, light lens that carries easily. The body measures 2.79 in (70.8 mm) across.

The front takes screw-in filters on a 55mm thread. A polariser can cut glare on wet leaves, and a plain filter guards the front element.

The headline specification is magnification. This lens reaches 1x, which is true life-size macro: the subject appears on the sensor at actual size. That suits tiny subjects such as insects, coins, stamps and jewellery, where fine texture is the point.

It focuses as close as 0.5 ft (16 cm). At that distance the subject sits close to the front element, so light can struggle to reach it. A small LED panel placed beside the lens solves that without spooking live subjects.

The maximum aperture is f/2.8. Depth of field at life-size magnification is extremely thin, so close-up work usually stops down for usable sharpness across a subject. Focus stacking, taking several shots at slightly shifted focus, is the common fix.

For people and general scenes at ordinary distances, the 50mm focal length gives a natural perspective. Food and indoor product shots also work well at this focal length. At f/2.8, portraits get less background blur than a faster 50mm prime gives wide open. Its optics specification score is 78/100.

There is no built-in stabilization. At macro distances even small hand movements show in the frame, so a tripod, a focusing rail or a flash becomes part of the routine. Faster shutter speeds carry the rest of the load, but they demand more light in return. The features score is 32/100.

It does carry weather sealing, which helps in damp or dusty outdoor conditions when shooting plants and insects. There is no fluorine coating on the surfaces, so cleaning dust and smears takes a little more care. The sealing matters when working low among plants in dew.

The eight elements in seven groups include aspherical surfaces and low-dispersion glass. The aspherical surfaces help correct distortion and spherical aberration. The low-dispersion glass helps reduce chromatic aberration, which appears as coloured fringes along high-contrast edges such as a shiny beetle's back. Fringes show most easily on small, detailed close-up subjects, so the glass choice suits this lens's purpose. Its construction specification score is 31/100.
