The SEL11F18 is the Sony FE 11mm F1.8, a compact ultra-wide-angle prime lens for Sony APS-C mirrorless cameras (E-mount).It features an 11mm focal length, which gives an extremely wide field of view (around 16.5mm full-frame equivalent). This makes it perfect for landscapes, vlogging, architecture, interiors, and astrophotography, where you want to capture a very wide scene in a single frame.
The lens has a bright F1.8 aperture, which helps in low-light shooting and night sky photography, while also allowing some background separation even in a wide-angle lens. As part of Sony’s G series, it delivers high sharpness, minimal distortion, fast and silent autofocus, and a very lightweight design (~181g), making it ideal for travel and handheld shooting.
