TTArtisan FF 50mm T2.1 E

TTArtisan FF 50mm T2.1 E – World-First Dual-Mode Bokeh Cine Lens: Switch between dreamy “bubble” and creamy soft bokeh in one click, bright T2.1 full-frame, 11-blade aperture, 320° focus throw (Soft mode), 0.8 Mod cine gears, all-metal weather-resistant build, 82 mm filter thread.

The TTArtisan FF 50mm T2.1 E is a groundbreaking full-frame cine lens that gives you two completely different bokeh personalities in a single barrel. With a simple flip of the dedicated switch, instantly transform from classic creamy soft blur to the romantic, circular “bubble bokeh” made famous by vintage Sonnar designs.

A fast T2.1 aperture delivers outstanding low-light performance and strong subject-background separation, while the 11-blade iris creates perfectly round highlights in Bubble mode and silky smooth fall-off in Soft mode. In Soft mode, the lens offers an ultra-long 320° focus rotation for pinpoint 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 both focus and iris rings, declicked aperture, and aviation-grade aluminum construction, it feels solid yet weighs only ~727 g (Sony E). 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 character-rich, emotional rendering.
