Description — Sony SEL50F18F
The Sony FE 50mm f/1.8 is a prime lens designed for Sony E-mount mirrorless cameras with full-frame coverage. The 50mm focal length sits squarely in the standard range, making it a natural fit for a wide variety of photographic subjects and scenarios. The f/1.8 maximum aperture is one of the lens's most notable attributes, providing meaningful light-gathering capability and the ability to work effectively in a range of lighting conditions.
The lens supports both autofocus and manual focus, giving users control over how they engage with their subjects. Weighing just 186g, this is a compact and light option that pairs well with the slim profile of modern mirrorless bodies. The 49mm filter thread keeps filter accessories affordable and easy to source.
