Brightin Star 24mm f/1.8 Review

The Sony Brightin Star 24mm f/1.8 is a fast, wide-angle prime that's built for full-frame Sony cameras. It lands in the 94th percentile for bokeh quality and the 88th for aperture, which means you're getting a seriously bright lens that can blur a background beautifully. At 445 grams, it's not the lightest, and it lacks weather sealing, but the optical performance punches well above its price point.

This lens scores a 90/100 for portraits, which is impressive for a 24mm. It's also rated 79.5/100 for professional work. The trade-off is clear in its 47/100 travel score. It's a specialist, not a generalist. You buy this for its specific optical strengths, not for a lightweight walk-around kit.

Let's talk about what this lens does well. Its f/1.8 aperture puts it in the 88th percentile, making it a low-light monster. Pair that with optical performance in the 84th percentile, and you've got a sharp, contrasty image maker. The bokeh, sitting at the 94th percentile, is exceptionally smooth for a wide-angle, thanks in part to that 11-blade diaphragm. That's why it's a portrait beast despite the focal length.

Now, the compromises. Autofocus performance is in the 47th percentile. The STM motor gets the job done, but it's not the fastest or quietest. There's no stabilization either (39th percentile), so you'll want a camera body with IBIS or steady hands. Minimum focus distance is 320mm, which puts macro capability in the 58th percentile. It's fine for general close-ups, but don't expect true 1:1 reproduction.

At $329, this lens is all about price-to-performance ratio in specific areas. You're paying for that 94th-percentile bokeh and 88th-percentile aperture speed. Compared to first-party Sony glass, you're saving hundreds of dollars while getting optical performance that can hang with more expensive options. The value is in accepting the trade-offs—slower AF, no stabilization, no weather sealing—to get that core image quality.

Stacked against popular third-party options, the Brightin Star's story is clear. The Viltrox 35mm f/1.7 is often cheaper and more versatile, but its bokeh and optical scores won't touch this 24mm's. The Meike 55mm f/1.8 Pro is a better portrait focal length for many, and it often has better build and AF, but you lose the wide-angle perspective. Compared to a Sony 24mm f/1.4 GM, you're giving up speed, flawless AF, and weather sealing for a fraction of the cost. This lens carves its niche by offering near-GM bokeh quality at a budget price, but you pay for it in other departments.

If you're a Sony full-frame shooter who values beautiful background blur and low-light capability in a wide-angle prime, and you're on a tight budget, this lens is a compelling data-backed pick. Its 94th-percentile bokeh is the real deal. But if you need snappy autofocus for video, built-in stabilization, or a lightweight travel lens, look elsewhere. This is a tool for a specific job, and for that job, it overdelivers for the price.
