Brightin Star 50mm f/1.05 Review
The Brightin Star 50mm f/1.05 offers stunning bokeh you can't get anywhere else for $270, but only if you're willing to focus manually for every single shot.
The 30-Second Version
The Brightin Star 50mm f/1.05 is a manual focus lens that delivers stunning, 100th-percentile bokeh for just $270. Its f/1.05 aperture is its superpower, but it trades autofocus and stabilization to hit that price. Buy it if you want an ultra-creamy look for portraits and don't mind focusing manually. Skip it if you need autofocus for anything.
Overview
So you're looking at a 50mm f/1.05 lens for $270. That's not a typo. The Canon Brightin Star is a manual focus prime that throws the rulebook out the window, offering an aperture so wide it lands in the 98th percentile. This isn't a lens for your everyday walk-around kit. It's a specialized tool for photographers and videographers who want to chase that ultra-shallow depth of field and dreamy bokeh on a budget.
It's a full-frame lens for the Canon RF mount, which means it covers your sensor completely. The build is decent, scoring in the 58th percentile, but don't expect weather sealing or stabilization. It's a simple, heavy (635g) metal tube with a focus ring. The optical design includes two HR (High Refractive) and two LD (Low Dispersion) elements to try and tame the wild light coming through that massive glass.
Who is this for? Our scoring says it's strongest for portraits (83/100) and solid for professional and video work (both 64.6/100). If you're the type who loves to shoot wide open, loves manual focus, and wants to create images with backgrounds that melt away into pure cream, this lens is talking to you. It's weakest for travel (33.6/100), which makes sense given its heft and lack of autofocus.
Performance
Let's talk about what that f/1.05 aperture actually does. In our database, its bokeh quality scores in the 100th percentile. That's the highest possible score. The 15-blade diaphragm creates incredibly smooth, circular out-of-focus highlights that are just buttery. This is the lens's party trick, and it delivers. The trade-off is that optical performance, while good at 68th percentile, isn't class-leading. You'll likely see some softness and chromatic aberration when shooting wide open, which is kind of the point of buying it.
In practical terms, this lens is about creative control, not clinical sharpness. That 1.9-foot minimum focus distance gives you a bit of flexibility for tighter shots, though its 1:8 magnification ratio (48th percentile) means it's not a macro lens. You're trading autofocus speed (46th percentile) and stabilization (37th percentile) for that unique look. For video, the manual focus is a plus for pull-focus shots, but you'll need a good rig or steady hands to compensate for the lack of IS.
Pros & Cons
Pros
- Unbeatable bokeh for the price: The 100th percentile bokeh score and 15-blade diaphragm create stunning, creamy backgrounds you can't get from cheaper f/1.8 lenses. 100th
- Extremely fast aperture: f/1.05 is ridiculously wide, letting in tons of light for low-light shooting and offering extreme depth of field control. 98th
- Solid build quality: For a third-party manual lens, the 58th percentile build score indicates a well-made, mostly metal construction that feels substantial. 69th
- Excellent value for a specialty look: At $270, it's one of the most affordable ways to get an f/1.0-ish aperture on a full-frame camera.
- Full-frame coverage: Works perfectly on RF-mount full-frame bodies, and can be used on APS-C cameras for a roughly 80mm equivalent field of view.
Cons
- Manual focus only: This is a deal-breaker for fast-paced or action photography. You have to nail focus yourself every time.
- No image stabilization: Combined with manual focus, this makes handheld shooting in low light a real challenge.
- Optical compromises wide open: Expect some softness and color fringing at f/1.05; it's a character lens, not a sharpness champion.
- Heavy and not versatile: At 635g, it's a chunk of glass. Its versatility score is low (39th percentile), meaning it's a one-trick pony.
- Not weather-sealed: You won't want to take this out in the rain or dusty conditions, limiting its use for adventure or travel photography.

Value & Pricing
Here's the bottom line: you are paying $270 for an optical effect that normally costs over a thousand dollars. The value proposition is incredibly narrow, but if you want that specific f/1.05 look, nothing else comes close at this price. Canon's own RF 50mm f/1.2L is over $2000. Even Samyang's AF 50mm f/1.4 is around $500.
You're getting a premium-grade aperture on a budget-grade feature set. You trade autofocus, stabilization, and perfect corner-to-corner sharpness for that beautiful bokeh. If your priority is absolute optical perfection, this isn't it. If your priority is a unique creative tool that won't break the bank, it's a fascinating option.
vs Competition
Looking at the competitors our data surfaced, they're mostly in different leagues. The Viltrox 35mm f/1.7 and Meike 55mm f/1.4 offer autofocus but are for different mounts (Z and APS-C) and slower apertures. The Tamron 17-70mm f/2.8 is a versatile zoom for Sony, but f/2.8 is nowhere near as fast. The Yongnuo 50mm f/1.8 is an autofocus option, but again, f/1.8 is a world apart from f/1.05 in terms of light and background separation.
The real trade-off is between the Brightin Star and saving up for a native, autofocus lens. A used Canon EF 50mm f/1.4 with an adapter would be in a similar price range and give you autofocus, but the bokeh won't be as smooth. The Brightin Star asks you to give up convenience for a look. The competitors offer convenience but can't match the extreme aperture. It's a classic spec-for-feature swap.

Common Questions
Q: How hard is it to focus manually at f/1.05?
It's challenging. The depth of field is razor-thin, so even slight movement can throw your subject out of focus. Using focus peaking and magnification aids on your mirrorless camera is essential. It's not for fast action, but with practice, it's manageable for posed shots.
Q: Is it sharp when stopped down?
Yes, optical performance improves significantly when you stop down. Our 68th percentile optical score reflects its potential. By f/2.8 or f/4, you should see much better sharpness across the frame, though it may never match the clinical sharpness of more expensive lenses.
Q: Can I use this on a Canon R7 or R10 (APS-C camera)?
Absolutely. On an APS-C body, the lens will have a crop factor, giving you an effective field of view similar to an 80mm lens on a full-frame camera. This can actually be great for portraits. You still get the full f/1.05 aperture for light gathering and bokeh.
Q: What's the catch with the $270 price?
The catch is the feature set. To hit this price with an f/1.05 aperture, Brightin Star cut autofocus motors, image stabilization, weather sealing, and used an optical design that prioritizes bokeh over absolute corner-to-corner sharpness. You're paying for the glass, not the electronics.
Who Should Skip This
Skip this lens if you need autofocus. That means event photographers, sports shooters, journalists, or anyone who photographs unpredictable subjects. The manual focus will cost you shots. Also skip it if you're a travel photographer. Our data scores it at 33.6/100 for travel for a reason. It's heavy, not sealed, and its lack of versatility makes it a burden on the road.
Instead, those users should look at the Canon RF 50mm f/1.8 STM. It's tiny, light, has autofocus, and is incredibly sharp for its price. If you have a bigger budget and want better optics with autofocus, the Sigma 50mm f/1.4 DG DN Art for E-mount (with an adapter) or saving for a used Canon RF 50mm f/1.2L are the paths to take. The Brightin Star is for a different, more patient kind of shooter.
Verdict
We'd recommend the Brightin Star 50mm f/1.05 to a very specific photographer: the portrait artist, the low-light enthusiast, or the videographer who works on a tripod or gimbal and loves manual focus pulls. If you have the time to focus carefully and you're chasing that ultra-creamy bokeh aesthetic, this lens is a shockingly affordable way to get it. It's a fun, creative lens that encourages you to slow down and compose.
For everyone else, it's a hard pass. If you shoot events, kids, pets, or anything that moves unpredictably, the lack of autofocus will drive you mad. If you're a travel photographer, the weight and lack of sealing make it a poor choice. If you need one lens to do everything, look at a standard 50mm f/1.8. This is a specialty item, and it's brilliant at its one job.
