7Artisans Spectrum 50mm T2.0 25mm
The 50mm full-frame design pairs a constant T2.0 aperture with a 12-blade diaphragm for smooth bokeh and a 270-degree focus throw for precise manual pulls. ED glass and high-refractive-index elements suppress color fringing, while the stepless gear ring adapts directly to follow-focus rigs. Best for indie filmmakers and videographers needing a deliberate, full-frame cinema lens with controlled focus on Sony E, L-mount, or Nikon Z cameras.
