Sony E 15mm F/1.4 G SEL15F14G

This 2022 prime gives Sony E mount APS-C photographers a wide-angle view with a bright f/1.4 aperture. That pairing suits street photography, tight interiors, landscapes and the night sky. The trade-off is the single focal length. You reframe by moving yourself, not a zoom ring.

The compact body is useful in a walking kit. Check whether the wide view suits your subjects, particularly when a person must occupy much of the frame. Distant details may call for a longer lens.

Sony designed this lens for APS-C coverage. There is no built-in image stabilisation. A camera with body stabilisation can help with shake, while firm support is useful for long exposures in dim light.

The lens weighs just 7.7 oz (219 g), and its 2.74 in (69.5 mm) length keeps it compact on small bodies. A screw-in filter attaches directly to the 55mm thread, so a polariser or ND filter is easy to fit for landscape work.

The 15mm focal length gives a wide view on the APS-C sensor. That framing suits narrow streets, small rooms, group pictures and open landscapes. It also means distant subjects stay small, so you get context rather than a filled frame.

The f/1.4 aperture is the defining strength. That wide opening lets a lot of light through, so you can keep ISO settings low in dim interiors, at dusk and for night-sky work. For anyone shooting wide views in poor light, that opening is the main draw.

Depth of field depends on aperture and focus distance. At f/1.4, a close foreground detail can have a soft background. In manual focus, closest focus is 0.6 ft (17 cm) and maximum magnification is 0.15x. These are the manual-focus limits. A nearby rock, plant or doorway can become part of a wider scene.

Move the camera to adjust the relationship between foreground and background. Stop down when more depth of field is needed, then check both near and distant details. Allow space ahead of the lens for light, especially when the subject is close.

The weather sealing resists dust and moisture, which suits landscape and street work in wind, dust or damp air. It covers realistic outdoor conditions rather than unlimited rain exposure.

There is no image stabilisation in the lens. Choose a shutter speed that suits both camera shake and subject movement. A tripod supports a still composition during a long exposure, but people and wind-blown plants can continue to move.

Remove loose grit before wiping the front glass. Check for marks when photographing towards a bright window or lamp. Keep both ends capped during transport and dry the exterior before putting the lens away.

Sony arranges 13 elements in 12 groups. The design includes aspherical surfaces, which help correct the distortion that can curve straight edges in wide frames. Super-low-dispersion glass helps reduce chromatic aberration, the coloured fringes that can gather along high-contrast edges in night scenes.

Internal focusing keeps the barrel length unchanged while you focus, so the lens stays the same size in use.
