Brightin Star AF 12mm f/2.8

The Brightin Star AF 12mm f/2.8 is an ultra-wide autofocus lens designed for Sony cameras, offering a 122.5-degree field of view in a rectilinear design. This makes it a capable option for landscape, architecture, and interior work where you need to capture expansive scenes without the circular distortion of a fisheye. Reviewers note that the lens maintains straight lines across the frame, a critical feature for rectilinear ultra-wides.

Sharpness is a highlight, with reviewers praising good edge clarity and overall image quality. The f/2.8 maximum aperture also makes it suitable for low-light shooting and video work, where its performance is specifically called out. Vignetting is present but described as manageable, meaning it won't be a deal-breaker for most use cases. For Sony shooters looking for an affordable ultra-wide with autofocus, this lens delivers solid optical performance in a practical package.
