Obiettivo Sony SEL50F18 50mm f/1.8 OSS

The Sony SEL50F18 is a 50mm prime lens for Sony E-mount MILC cameras. With a bright f/1.8 maximum aperture, built-in Optical SteadyShot (OSS) image stabilization and a compact lightweight design, it is designed to deliver sharp images, smooth bokeh and reliable low-light performance for portraiture and general photography.

Advantages

The lens combines a fast f/1.8 aperture with OSS to allow clearer handheld shots in low light and smoother video capture. A 7-blade circular aperture produces rounded, natural defocusing (bokeh). Internal focusing keeps the barrel stationary for faster autofocus response and a compact form. Optical design minimises distortion and chromatic aberration for refined image quality.

How to use

Attach the lens to a compatible Sony E-mount camera and ensure it is properly locked. Use the maximum aperture (f/1.8) for shallow depth of field and low-light situations; stop down toward f/5.6–f/11 for greater depth of field and increased sharpness across the frame. Enable the camera’s OSS functionality if required — the lens also contains Optical SteadyShot to reduce camera shake for handheld photos and videos. For autofocus, half-press the shutter or use the camera’s AF controls; switch to manual focus on the camera body if fine control is needed.

Recommendations

For portraits, position the subject several metres from the background and use the f/1.8 aperture to create pronounced background separation. Use a 49 mm UV or protective filter to protect the front element and keep the lens cap on when not in use. For sharper results in bright conditions, stop down slightly and use a tripod for critical work.
