Brightin Star officially launched its MF 50mm f/2 TRI-SIGHT full-frame manual focus lens today at a $349.99 introductory price. The launch had been a long time coming — the lens first showed at CP+ in February 2026, and now it is on sale simultaneously across Sony E, Canon RF, Nikon Z, and L-Mount, with a regular price of $399.99.
The headline feature is the three rendering modes you can swap on a single barrel ring: SMOOTH for a soft-focus look, PRIME for a standard, neutral rendering, and FOAMS for bubble bokeh. That's unusual for a manual focus prime at this price — most 50s give you one personality and expect you to commit. PetaPixel, which covered the launch on September 28, notes that the FOAMS mode also has a different minimum focus distance than PRIME (0.7m vs 0.8m) and SMOOTH (0.9m), so each mode is slightly re-engineered, not just a software preset.
Behind the mount there's also a drop-in filter slot. Brightin Star ships four rear inserts — triangle, star, clover, and butterfly — that reshape out-of-focus highlights. If you've used a Lensbaby, the idea is familiar. The lens itself is 7 elements in 6 groups, has an 11-blade aperture, and weighs between 429 and 454 grams depending on the mount. Nikon Rumors' spec sheet lists 459g; Photography Talk measured an L-mount copy at 436g.
On the spec side, this is a fairly simple lens: f/2 to f/22 on a de-clicked aperture ring, 47° angle of view, 37.5mm filter thread, manual focus only. It's not trying to compete with the Sony 50mm f/1.4 GM on sharpness — Sony's lens lists at $1,398 at B&H, Nikon's Nikkor Z 50mm f/1.4 sits at $1,248, and Sigma's 50mm f/1.4 DG DN Art was launched at $849 and currently lists under $700. At $349.99, the TRI-SIGHT is asking to be evaluated on a different axis. The point is character, not clinical rendering.
I haven't handled this lens, and I haven't tested it. So I can't speak to whether the three modes feel meaningfully different in the hand, or whether the de-clicked ring is smooth enough to pull focus with. What I can say is the concept lands. A $349 lens that gives you three different renderings and a slot for shaped bokeh is closer in spirit to a Lensbaby or a Voigtländer than to a Sigma Art, and that positioning is what Brightin Star seems to be going for.
For owners of a Sony A7 IV, a Nikon Z f/1.8 shooter, or anyone running an older L-mount body who wants to spend less on a creative prime than on a clinical one, this is the most interesting 50mm to launch this month. The CP+ preview generated real discussion back in February; the September 28 release closes that loop.
The lens is available now at Brightin Star's official store and on Amazon. If you want a 50mm that does something different for under $400, this is one to read carefully before the introductory price expires — Brightin Star hasn't said when the price goes back to $399.99.
