Description — Sony SEL50F18
The Sony E 50mm f/1.8 OSS is a prime lens designed specifically for Sony E-mount APS-C mirrorless cameras. Its f/1.8 maximum aperture provides solid light-gathering performance and the ability to work with selective focus techniques. One of its standout features is built-in Optical image stabilization (OSS), which helps deliver sharper results in situations where camera shake could be a concern — especially valuable on bodies without in-body stabilization.
Autofocus is fully supported alongside manual focus, giving photographers control over how they acquire focus in any situation. The 49mm filter thread keeps this lens compatible with a compact range of filters, and at just 202g, it is genuinely lightweight and easy to carry all day. As a standard focal length prime in the APS-C format, it covers a versatile range of shooting applications.
Mount compatibility is Sony E only, making this a dedicated solution for that mirrorless ecosystem.
