NiSi T1 Prime 50mm T1
Summary
The NiSi T1 PRIME 50mm T1.0 is a full-frame cinema prime designed to perform beautifully wide open. Where earlier T1.0 lenses softened, lost contrast and showed chromatic aberration at maximum aperture, the T1 PRIME 50mm stays clean, sharp and high in contrast at T1.0, giving filmmakers ultra-shallow depth of field and a dreamy, painterly bokeh without compromise. Built around a 16-element optical design, an 18-blade iris, and a precision focus-pulling mechanism, this LPL-mount prime is engineered for full-frame, VistaVision and large-format cinema cameras.
