Brightin Star 50mm f/1.05 50mm

The Brightin Star 50mm f/1.05 gives you an f/1.05 aperture for 255 USD, which is basically unheard of. User sentiment sits at the 91st percentile with a 92/100 score, so owners genuinely love this thing. But it's manual focus only, has no stabilization, and optical quality lands at the 41st percentile, so it's a specialty tool for patient shooters.

Let's talk about that f/1.05 aperture, because it's the entire reason this lens exists. At maximum aperture, you're letting in an enormous amount of light, which means you can shoot handheld in conditions that would send most lenses crying for a tripod. The 10 elements in 8 groups do a decent job controlling aberrations at wide apertures, though optical quality overall sits at the 41st percentile. That's not a knock on the lens, it's just reality: ultra-fast budget glass always makes compromises somewhere. The bokeh quality lands at the 57th percentile, which is solid for a lens this cheap. The 15-blade diaphragm helps here, producing smoother out-of-focus areas than you'd expect at this price point.

The minimum focus distance of 570mm (22.4 inches) gives you decent subject separation for portraits and product shots. Macro performance sits at the 54th percentile, so don't expect true macro capability, but you can get close enough for detail shots. The manual focus ring is smooth and well-damped, which matters a lot when you're trying to nail focus at f/1.05 where the depth of field is paper-thin. We'll be blunt: focusing this lens wide open takes practice. The autofocus score is 15th percentile because there is no autofocus, and that's going to be the dealbreaker for a lot of people.

Stacked against the competition, the Brightin Star occupies a strange niche. The Meike MIX Series 85mm F1.4 II is probably the closest rival in spirit, another budget manual focus portrait lens, but it's an 85mm and doesn't hit f/1.05. The Sigma Contemporary 18-50mm f/2.8 DC DN is a completely different beast, a versatile zoom with autofocus, but it can't touch the Brightin Star's light-gathering ability or depth of field control. The Tamron Di III VC 28-300mm f/4-7.1 offers stabilization and autofocus but at much slower apertures. What the Brightin Star gives up in versatility (34th percentile) and autofocus (15th percentile), it makes up for in raw aperture speed and price. It's not competing with zooms, it's competing with your willingness to slow down and focus manually.

At 255 USD, this lens is punching way above its weight class. You're getting an f/1.05 aperture for less than the cost of most f/1.8 primes from first-party manufacturers. The value proposition is simple: if you want the shallowest depth of field possible without spending a grand or more, this is basically your only option. The build quality at the 44th percentile means it's not going to survive a drop onto concrete, but the all-metal construction feels more premium than the price suggests. For portrait shooters on a budget who don't mind manual focus, this is a steal. For everyone else, the compromises might outweigh the savings.

The Brightin Star 50mm f/1.05 is a weird lens, and we mean that in the most interesting way possible. You're getting an f/1.05 aperture on a full-frame Canon RF mount for around 255 USD, which is frankly absurd when you look at what first-party glass costs. That aperture sits at the 52nd percentile in our database, which sounds middle of the pack until you realize most of the lenses ahead of it cost four figures. The trade-off? Manual focus only, no stabilization, no weather sealing, and a build quality that lands at the 44th percentile. This is a specialty tool, not a daily driver.

But here's the thing: user sentiment for this lens sits at the 91st percentile with a 92/100 sentiment score. People who buy this lens know exactly what they're getting into and they love it for what it is. The social proof is even stronger at the 99th percentile, which tells us this lens has built a small but passionate following. If you want razor-thin depth of field and dreamy bokeh on a budget, this thing delivers. If you want autofocus, look elsewhere immediately.

Skip this lens if you need autofocus, period. The AF score is 15th percentile because there is no autofocus, and that's a dealbreaker for event shooters, sports photographers, or anyone shooting moving subjects. Also skip it if you shoot in wet or dusty conditions, since there's no weather sealing. The stabilization score at the 35th percentile means handheld shooting at slower shutter speeds is going to be rough, especially combined with the 614g weight. If you're a hybrid shooter who needs video autofocus or a travel photographer who wants something light and versatile (travel score is 20.8/100, the weakest area), this lens will frustrate you. This is a studio and portrait lens for people who enjoy the manual focus process.

The Brightin Star 50mm f/1.05 is a specialty lens that knows exactly what it is. The 92/100 user sentiment score and 99th percentile social proof tell the real story: the people who buy this lens are thrilled with it. The f/1.05 aperture delivers genuinely unique images at a price that's hard to believe. But the manual focus, lack of stabilization, and mediocre optical quality at the 41st percentile mean this is not a lens for everyone. If you're a portrait shooter who wants dreamy, ultra-shallow depth of field and you're willing to work for it, this is a fantastic buy. If you need autofocus or shoot in unpredictable conditions, keep looking.
