Brightin Star 12mm f/2.8 12mm

★★★★★ 4.7 (286)

Its 11mm focal length and f/2.8 aperture deliver a full-frame 180-degree field of view, and the 8-blade diaphragm creates pronounced eight-point sunstars during night shooting. The 0.17m minimum focus distance enables extreme close-up shots with exaggerated perspective, supported by an optical design of 8 elements in 11 groups with one ED lens for edge-to-edge sharpness. This lens suits astrophotographers and architectural photographers who need a manual-focus, ultra-wide fisheye for dramatic low-light compositions.

  1. Q4 202572/1004.0★5 レビュー

    Most buyers praise the lens for its wide field of view, light weight, and good value, but one report cites poor focus and vignetting.

    • Wide field of view and lightweight design praised by multiple buyers.
    • Good value for the price, with robust feel noted.
    • One review reports low quality, poor focus, and vignetting.
    • Excellent image clarity and low distortion, exceeding expectations.
  2. Q3 202567/1003.6★9 レビュー

    Buyers praise the lens for its unique ultra-wide rectilinear view and build quality, but many note serious optical issues like softness, vignetting, flares, and durability concerns.

    • Unique ultra-wide rectilinear lens with excellent build, but significant vignetting, soft corners, and flares.
    • Two users reported the lens falling apart: aperture ring misaligned, focus ring stopped working.
    • Worst wide-angle lens ever used by one buyer: too soft at all apertures even stopped down.
    • Great for landscapes and architecture; compact, metal build works well with Sony 7 series.
  3. Q2 202590/1004.8★5 レビュー

    Buyers praised the lens for sharpness, build quality, and value, especially in bright conditions, but noted low-light softness and a learning curve for this specialty lens.

    • Excellent sharpness and build quality for the price, with good flare control.
    • Includes ND filters for long exposures, enhancing creative options.
    • Chromatic aberration present but correctable in post-processing; low-light performance weak.
    • Specialty lens requires learning; not an all-rounder, but rewarding for niche use.
