Brightin Star 50mm f/1.05 Review

The Brightin Star 50mm f/1.05 is a manual focus lens that offers an exceptionally wide aperture at a shockingly low price. It creates stunning, creamy bokeh and excels in low light, but requires patience to focus and isn't the sharpest tool wide open. It's a fantastic creative option for portrait and video shooters on a budget.

If you're looking for a lens that can blur a background into oblivion, the Brightin Star 50mm f/1.05 for Nikon Z mount is a fascinating option. It's a manual focus prime lens that offers an aperture so wide it's almost comical, letting in a massive amount of light for a price that's surprisingly low. This isn't your typical autofocus workhorse, but for portrait photographers, videographers, or anyone chasing that dreamy, cinematic look, it's a tool that demands attention. At around $270, it's a fraction of the cost of other ultra-fast lenses, which makes it a tempting experiment for creative shooters.

Let's talk about what this lens does best: bokeh and light gathering. With an f/1.05 aperture, it sits in the 98th percentile for aperture speed. In practice, that means you can shoot in near-darkness and get a depth of field so shallow you can isolate a single eyelash. Our data shows it scores a perfect 100th percentile for bokeh quality, and the 15-blade diaphragm helps keep out-of-focus highlights looking smooth and round. The trade-off is in other areas. Its optical performance lands in the 68th percentile, so expect some softness and chromatic aberration wide open, which is pretty typical for a lens this fast. It's a specialist, not an all-rounder.

At $270, the value proposition is simple: you're paying for the aperture. You simply cannot get another f/1.05 lens for anywhere near this price for the Z mount. The closest competitors in speed cost thousands. You are making clear compromises for that speed—namely, giving up autofocus and some optical perfection—but if your goal is to achieve a specific look on a tight budget, it's a compelling deal. It's the lens you buy for the shots you can't get with anything else in your bag.

This lens exists in its own weird niche, but let's look at some alternatives. If you want autofocus and more versatility in a normal prime, the Viltrox 35mm f/1.7 Z is a similar price but gives you AF and a slightly wider field of view, though it's much slower at f/1.7. The Tamron 17-70mm f/2.8 for Sony (or similar zooms for Z-mount) offers a huge zoom range and stabilization, but its f/2.8 aperture can't compete with f/1.05 for background separation. For Nikon shooters wanting a fast 50mm with AF, the native Nikon Z 50mm f/1.8 S is optically superb but costs more and is 'only' f/1.8. The Brightin Star is for when the number after the 'f/' is the only thing that matters.

Skip this lens if you shoot fast-moving subjects like sports, wildlife, or active kids, as manual focus will be a constant struggle. Travel photographers should also look elsewhere, as its weight and lack of versatility score poorly. If you need pin-sharp results across the frame for commercial work, the optical compromises at f/1.05 might not be acceptable. In those cases, a sharper, autofocus prime like the Nikon Z 40mm f/2 or the Viltrox 35mm f/1.7 would be a better fit.

Should you buy the Brightin Star 50mm f/1.05? Only if you know exactly what you're getting into. This is not a do-everything lens. It's a creative tool for specific moments: moody portraits, low-light street scenes, or cinematic video where manual focus is part of the workflow. If you're a photographer who loves to shoot wide open and doesn't mind slowing down to nail focus, it's a blast and offers a look that's hard to replicate. But if you need reliable autofocus for kids, pets, or events, or if you prioritize razor-sharp corner-to-corner performance, you'll be frustrated. It's a purpose-built toy for grown-ups.
