Brightin Star 35mm F1.7 Review
For just $70, you get a metal-built, stabilized f/1.7 lens. The low-light performance is fantastic, but the autofocus and optical sharpness show the budget roots.
Overview
The Brightin Star 35mm F1.7 is a weird little lens that's shockingly good at one thing: getting you a fast aperture for under a hundred bucks. It's not the sharpest tool in the shed, and the autofocus is just okay, but for $70, you're getting a metal-built, stabilized prime that punches way above its price tag. Just know it's a specialist, not a daily driver.
Performance
Where this lens really surprised me was in low light. That f/1.7 aperture lets in a ton of light, and the in-lens stabilization is legitimately good, sitting in the 92nd percentile. You can handhold shots in dim conditions you'd normally need a tripod for. The surprise on the flip side? The optical quality is only in the 32nd percentile. Corners get soft wide open, and it's not the lens you'd pick for critical detail work.
Pros & Cons
Pros
- Insane value for $70. A metal lens with stabilization at this price is unheard of. 93th
- Fantastic for low-light and casual portraits thanks to the f/1.7 aperture. 88th
- Solid, compact metal build that feels much more expensive than it is. 81th
- Image stabilization works really well, making it great for handheld video. 80th
Cons
- Autofocus is slow and hunts sometimes. It's fine for static subjects, but forget fast action.
- Optical sharpness, especially away from the center, is just average.
- Not versatile at all. It scored terribly for travel, so it's a one-trick pony.
- No weather sealing means you need to baby it a bit.

Value & Pricing
At $70, it's an absolute steal. You're paying for the aperture and stabilization, and you get both in a solid package. There's no question it's worth the money if your needs match its strengths.
vs Competition
The obvious competitor is the Viltrox 35mm f/1.7. It's a bit more expensive, but it typically has better autofocus and slightly sharper optics. If you need reliable AF, spend the extra on the Viltrox. But if your budget is locked at $70 and you shoot mostly still subjects, the Brightin Star's stabilization gives it a unique edge the Viltrox lacks. Don't even look at the Panasonic 14-140mm zoom here; that's for versatility, not low-light performance.
Verdict
Buy this lens if you're on a razor-thin budget and want to experiment with a fast prime for portraits, pets, or low-light still lifes. Its stabilization is a game-changer for the price. Skip it if you need snappy autofocus, pin-sharp corner-to-corner detail, or a lens you can take anywhere in any weather.
