The 30-Second Version

A $70 manual focus prime for Micro Four Thirds. Surprisingly well-built with great close-focus for macro, but optical sharpness is just okay. It's a fun, cheap experiment, not a workhorse lens. Worth it only if you're cool with manual focus.

Overview

The Brightin Star 35mm F1.7 is a weird little lens. It's a manual-focus prime for Micro Four Thirds cameras that costs about $70. For that price, you get a surprisingly solid metal build, a fast f/1.7 aperture, and a focal length that's decent for portraits and close-up work.

But here's the catch: it's a manual focus lens. That means no autofocus at all. You're turning the ring yourself for every shot. For some, that's a deal-breaker. For others, it's a fun, cheap way to play with a fast prime. Our database shows it's a niche performer, crushing it for macro but falling flat for landscapes.

Performance

Performance is a mixed bag, which you'd expect for seventy bucks. The standout feature is its close-focusing ability, scoring in the 93rd percentile for macro work. You can get really close to your subject. The f/1.7 aperture lets in a good amount of light, and the stabilization is decent, landing in the 87th percentile. The downsides are sharpness and versatility. Optical quality sits in the 35th percentile, so don't expect pin-sharp corners. And with a fixed 35mm focal length (which is a 70mm equivalent on MFT), it's not very versatile, scoring low there too.

Pros & Cons

Pros

  • Excellent close-focusing capability for macro shots. 93th
  • Solid, all-metal build feels much more expensive than it is. 88th
  • Fast f/1.7 aperture is great for low light and shallow depth of field. 83th
  • Smooth manual focus ring makes the process enjoyable. 81th

Cons

  • It's a manual focus-only lens, which will frustrate many.
  • Optical sharpness, especially towards the edges, is just okay.
  • The 35mm focal length on MFT isn't very versatile for general use.
  • Not weather-sealed, so keep it away from the elements.

The Word on the Street

4.3/5 (210 reviews)
👍 Many buyers are impressed with the solid, all-metal build quality, feeling it punches well above its price tag.
🤔 Users acknowledge the manual focus is a learning curve, but find the focus ring smooth and the process rewarding once you get the hang of it.
👎 A common note is that while the center sharpness is acceptable, the image quality towards the edges of the frame can be soft, especially wide open.

Value & Pricing

At $70, it's hard to call this a bad value. You're getting a metal lens with a fast aperture for less than a nice dinner. The question is whether you'll use it. If you enjoy manual focus and want a cheap lens for portraits, product shots, or macro experiments, it's a fun toy. If you need reliable, sharp autofocus for everyday shooting, this isn't it. You're paying for the experience and the aperture, not for optical perfection.

vs Competition

Stacked up, it's in a weird spot. Compared to the Viltrox 35mm f/1.7 for Z-mount, you're giving up autofocus for about $100 less. Against the versatile Tamron 17-70mm f/2.8 for Sony, you lose zoom range, autofocus, and optical consistency, but you gain a faster aperture and a much lower price. The real competition might be used, older manual lenses. This one wins on having a native MFT mount and modern build, but an adapted vintage lens might offer more character for similar money.

Common Questions

Q: Is this lens autofocus?

No, it is a manual focus-only lens. You control focus entirely by turning the focus ring on the lens barrel.

Q: What's the equivalent focal length on my Micro Four Thirds camera?

Due to the crop factor, this 35mm lens will give you a field of view similar to a 70mm lens on a full-frame camera. It's a short telephoto, good for portraits and details.

Q: How good is it for video?

The smooth manual focus ring is nice for pulling focus in video, but the lack of autofocus means you can't use continuous AF tracking. It's best for controlled, planned shots.

Who Should Skip This

Skip this lens if you need reliable autofocus for anything, especially moving subjects or quick snaps. Also, if you're after tack-sharp image quality across the entire frame, look at more established brands. This is a tool for tinkerers, not perfectionists.

Verdict

Buy this if you're a Micro Four Thirds shooter who wants to dabble in manual focus without spending much, or if you specifically need a cheap, fast prime for close-up work. It's a great 'second lens' for playing with depth of field and learning focus techniques. For everyone else, especially beginners or anyone who needs autofocus, there are better options, even at this price.
