TTArtisan FF 50mm T2.1 L – World-First Dual-Mode Bokeh Cine Lens (L-Mount): One-click switch between dreamy “bubble” and creamy soft bokeh, bright T2.1 full-frame, 11-blade iris, 320° focus throw (Soft mode), 0.8 Mod cine gears, durable all-metal build, 82 mm filter thread.
A 50 mm full-frame cine lens with manual focus and a T2.1 aperture. A switch on the barrel selects between the bubble bokeh of Bubble mode and the smooth, creamy blur of Soft mode.

In Soft mode you focus from 0.65 m and the focus ring turns 320°; in Bubble mode from 0.45 m with 131°–258° of rotation. The switch changes both the look of the blur and how focusing behaves.
Manual control, 11 aperture blades.
Optics designed for full frame.
50 mm on full frame.
Standard cine gear for follow focus.
The mode switch sits right on the barrel, and the focus ring carries two distance scales, one for each mode, because Bubble and Soft have different minimum focus distances.

The TTArtisan FF 50mm T2.1 L is a revolutionary full-frame cine lens that delivers two distinct bokeh personalities in a single barrel. A dedicated switch instantly toggles between classic creamy soft blur and the romantic, circular “bubble bokeh” made famous by vintage Sonnar designs.
Its fast T2.1 aperture excels in low light and delivers powerful subject isolation, while the 11-blade iris produces perfectly round highlights in Bubble mode and silky-smooth fall-off in Soft mode. Soft mode offers an ultra-long 320° focus rotation for surgical cinematic focus pulls; Bubble mode shortens rotation to 131°–258° for faster handling when needed.
Built to professional cine standards with 0.8 Mod gears on focus and iris rings, declicked aperture, and aviation-grade aluminum construction, it weighs only ~744 g (L-mount). Consistent 82 mm filter thread and near-identical front diameter across the TTArtisan cine trio make filter and matte-box swaps effortless. Perfect for narrative films, weddings, music videos, and any project that demands emotional, character-rich rendering on L-mount cameras (Panasonic, Sigma, Leica).
