From TTArtisan:

Break away from the ordinary— A dual-bokeh cine lens full of character

One lens, two dreamy bokeh

Unlike traditional cine lenses, TTArtisan Cine lens series offers both Bubble Bokeh and Soft Bokeh modes to deliver two completely distinct visual styles.

Using soft mode to bring a filter-like softness to the images, delivering a smooth and creamy background blur.

Every detail is delicately rendered, making it perfect for close-up portraits and emotional scenes, where every expression and movement captured through the lens is filled with emotion and depth.

In Soft mode, this lens allows you to capture softclose-up shots.

With its T2.1 aperture, this lens not only maintains excellent brightness in low-light conditions but also enhances the depth of images.

The lens features an 82mm filter thread, allowing you to pair it with a variety of filters to enhance the visual effects.

Length is the 90 mm L-Mount figure (C in the size table). The drawing gives 85 mm across the barrel and 88.5 mm across the focus and iris gear rings; diameter is 88.5 mm, the widest part. close_focus is the shorter of TTArtisan’s two figures: 0.45 m in Bubble mode (0.65 m in Soft mode). TTArtisan publishes no maximum magnification, so that field is empty. The angle of view is TTArtisan’s full-frame figure of 47 degrees.
