## New Lens Features
Brightin Star's MF 50mm F2.0 Tri-Sight lens has user-selectable rendering modes for out-of-focus highlights.

> Choose from Smooth bokeh (soft highlights), Prime (sharper, more defined highlights), or Foams (dreamy, bubble-like light flares)
## How It Works
A dedicated control ring adjusts a floating lens group to change bokeh style by altering light convergence.

> This moves a floating group of lens elements back or forth within the barrel to vary the focus distance, altering the convergence characteristics of light rays passing through the lens.
## Aperture Inserts
Four circular plate inserts create butterfly, star, triangle, or four-leaf clover shapes for out-of-focus highlights.

> These turn what would otherwise be round out of focus highlights into a choice of butterfly, star, triangle, or four-leaf clover shapes.
## Unique Mounting
Brightin Star unscrews a locking ring to fit inserts, unlike standard drop-in 37.5mm filters.

> Rather than slotting them down into the barrel, you unscrew a locking ring at the lens mount, fit the plate, then re-attach the ring.
## Physical Specs
The lens weighs 429g to 454g, measures 70mm to 74mm, and has an 11-blade de-clicked aperture.

> Weight ranges between 429g and 454g, and length between 70mm and 74mm, depending on mount option.
## Availability
Available now for Sony E, Canon RF, Nikon Z, and L-mount cameras at $349.99 or £263.99.

> The Brightin Star MF 50mm F2.0 Tri-Sight lens is available now for full-frame and APS-C Sony E, Canon RF, Nikon Z, and L-mount cameras, priced at $349.99/£263.99
## Key takeaway

Brightin Star launched a manual focus lens with rendering modes that change out-of-focus highlights and four-leaf clover-shaped bokeh.
