Brightin Star 50mm f/1.05 50mm

★★★★★ 4.8 (258)

The f/1.05 maximum aperture delivers extreme light gathering and razor-thin depth of field, while the 8-group, 10-element optical design with high-refractive and low-dispersion elements maintains sharp center resolution wide open. Its multi-layer coatings achieve 99.8% light transmittance to suppress flare, and the redesigned aperture ring improves manual handling despite the substantial 898g all-metal build. This lens is best for Nikon Z-mount photographers who prioritize low-light capability and distinct background separation over autofocus convenience.

Snapshot

The 30-Second Version

The Brightin Star 50mm f/1.05 is a manual focus, all-metal prime with an absurdly bright aperture and gorgeous bokeh. It's soft wide open and has zero modern conveniences, but at USD 270 to USD 300 it's a bargain for the look it delivers. Buy it for portraits and night shooting, skip it if you need autofocus or weather sealing.

Cons

What owners think

The Word on the Street

4.8/5 (258 reviews)
👍 Owners consistently praise the sharpness and snappy feel when paired with high-resolution bodies, with several saying they have no regrets about the purchase.
🤔 A few buyers mention a thud or shifting sound when the lens is off the camera, though most confirm it's normal and disappears once powered on.
👎 Some users note the manual focus system takes getting used to, especially for fast-moving subjects where nailing focus at f/1.05 is tricky.

The proof

Performance

Optically, this lens sits right around the middle of the pack in our database, which is honestly impressive for a budget f/1.05. The 10-element, 8-group design with 2 ED elements keeps chromatic aberration mostly in check, though you'll still see some purple fringing wide open if you go looking for it. Sharpness at f/1.05 is soft and dreamy, which some portrait shooters love, but stop down to f/2.8 or f/4 and it cleans up nicely. The manual focus ring is smooth and well-damped, but nailing focus at f/1.05 on a moving subject is a skill, not a feature. The 606g all-metal body feels solid in hand, though the lack of weather sealing means you'll want to baby it in rain or dust.

vs Competition

Stacked against the competition, the Brightin Star is in a strange lane. The Sigma Contemporary 18-50mm f/2.8 DC DN is sharper, lighter, and has autofocus, but it's an APS-C zoom that can't touch f/1.05. The Tamron Di III VC 28-300mm f/4-7.1 is far more versatile and stabilized, but it's slow and bulky by comparison. The Sony E 18-135mm f/3.5-5.6 OSS is a practical everyday lens, but it's boring next to this thing. If you want a dedicated portrait or low-light prime with character, the Brightin Star wins on vibe alone. If you need one lens that does everything, look elsewhere.

Price

Value & Pricing

Pricing is all over the map depending on where you shop. In the US, you'll find it between USD 270 and USD 300 across ten listings, with Amazon typically offering the best deal at the lower end. Canadian buyers see a wider spread, from CAD 346 to CAD 400, and again Amazon.ca tends to land near the bottom of that range. European pricing is steeper, around EUR 534 to EUR 580, which makes it a harder sell against used autofocus options. At the US price, this is a bargain for the aperture alone. At European prices, you're paying a premium for the novelty.

Overview

The Brightin Star 50mm f/1.05 is a weird, wonderful little lens. It's a fully manual, all-metal prime that opens up to a ridiculous f/1.05, which is about as close to 'night vision' as you can get without spending four times the money. No autofocus, no stabilization, no weather sealing. Just you, a focus ring, and a whole lot of bokeh.

For portrait shooters and anyone who loves shallow depth of field, this thing is a playground. The 15-blade diaphragm keeps out-of-focus areas creamy, and the 22.4 inch minimum focus distance lets you get close enough to make backgrounds melt. But it's a niche tool. If you need speed or autofocus, keep walking.

Common Questions

Q: Is the manual focus mechanical or focus-by-wire?

The Brightin Star 50mm f/1.05 uses a mechanical manual focus system, not focus-by-wire. That means the focus ring is directly connected to the lens elements, giving you a tactile, repeatable feel that's great for precise adjustments at f/1.05.

Q: Why does something inside the lens shift when it's not attached to a camera?

That movement is normal. The internal elements are designed to float when the lens is unpowered, and they engage once the lens is mounted and the camera is on. It's not a defect, just how this lens is built.

Q: Is this lens weather sealed?

No, the Brightin Star 50mm f/1.05 has no weather sealing. The all-metal barrel feels tough, but you'll want to keep it out of heavy rain, dust, and sand to avoid issues.

Who Should Skip This

Skip this if you shoot fast-moving subjects, need autofocus for events or wildlife, or plan to use it in rough weather. The manual focus and lack of sealing make it a poor fit for sports, wildlife, or travel photography in unpredictable conditions. If you need a reliable everyday 50mm with autofocus, grab a native mount option instead.

Verdict

This lens is for photographers who know exactly what they're getting into. Portrait shooters, street photographers who shoot at night, and anyone who loves the look of ultra-shallow depth of field will have a blast. It's not a beginner lens. Manual focus at f/1.05 requires patience and practice. But if you're willing to slow down and work for the shot, the Brightin Star 50mm f/1.05 rewards you with images that look like they came from a much more expensive piece of glass.
