This is not my first time trying out a fisheye lens. My first experience dates back to 2019, and it was with the 7Artisans 7.5mm f2.8. Back then, I still remember how rare it was for manufacturers to release an X-Mount version of their lenses.

Fast forward to 2026, and things have changed dramatically. Releasing an X-Mount version has become the norm, and honestly, that’s a great thing. Fujifilm’s decision to open up the mount has benefited everyone: the photographers, the community, third-party manufacturers, and of course, Fujifilm themselves. But that’s a story for another day.

Intro
Brightin Star released its first 7.5mm fisheye in 2019, followed by updates in 2021, 2024, and now the 4th generation in 2026. Not many manufacturers are willing to keep refining such a niche lens over the years, so I do appreciate the dedication. The real question is, do all these improvements actually make a difference?

Let’s find out.
Before I proceed further, I would like to thank the good people at Brightin Star for sending this lens over for review. As always, they have zero influence over what you’re about to read. Everything here is based purely on my own hands-on experience.



Design and Build Quality
One thing I have always liked about Brightin Star is that their lenses have their own identity.
Their signature bright yellow lettering against the black lens barrel makes their lenses instantly recognizable. For the silver version, the yellow is replaced with red lettering. It still looks good and gives the lens a premium appearance, although I do think the yellow has become part of Brightin Star’s identity and is easier to recognize from afar.


The lens itself looks modern and feels more compact than I initially expected. Weighing 278 grams, it sits comfortably in the hand without feeling front-heavy. I could immediately notice the difference after using the TTArtisan 7.5mm f2, which weighs around 370 grams. It isn’t exactly a fair comparison since they are different lenses for different photographers’ needs, but it does give you an idea of how lightweight this lens feels.



The aperture ring has a softer click than what I am used to on most manual lenses. Personally, I prefer a more pronounced click because it feels slightly more satisfying, but this comes down to personal preference rather than being a flaw.
Like almost every fisheye lens, it comes with a built-in lens hood. Considering how exposed the front element is, this is definitely a welcome addition. Last but not least, it comes with a metal lens cap too.

Image Quality
One thing I have noticed over the years is that image quality from third-party manufacturers has improved tremendously. Every new generation seems to get better, and this lens is no exception.

Wide open at f2.8, the images are already sharp with good contrast, producing results that are more than usable for everyday photography.

As expected from a fisheye lens, the sharpest area is right in the centre of the frame. Sharpness gradually drops towards the edges, and this is something I have observed on almost every third-party fisheye lens I have tested. It isn’t unique to Brightin Star.
Chromatic aberration, surprisingly, is very well controlled. At least throughout my testing, I didn’t come across anything obvious enough to bother me.
Vignetting is visible at f2.8, but that’s hardly surprising for an ultra-wide fisheye. Besides, it’s something photographers can easily correct during post-processing if they wish.
As for the sunstar, it performs reasonably well. The rays are clean and defined, although they aren’t the sharpest or most dramatic I’ve seen. And be mindful of the lens flare if you do not wish to have it in your frame.


Focusing
The manual focus ring rotates smoothly with very little resistance.


Some photographers may prefer a slightly stiffer focusing ring for more tactile feedback, while others will appreciate how effortlessly it turns. Personally, I can live with either.
The focus throw from the minimum focusing distance to infinity is roughly 90 degrees. Some photographers may find this travel a little short if they enjoy making very precise manual focus adjustments.

That said, this is a fisheye lens. Most of the time, you will be shooting at smaller apertures with everything in focus, so precise focusing isn’t usually a major concern.
Minimum Focus Distance (MFD)
The 15cm minimum focusing distance genuinely surprised me.
Being able to focus this close opens up plenty of opportunities for creative perspective shots, exaggerating foreground subjects while still capturing an incredibly wide background. Image quality remains consistent even at the minimum focusing distance, retaining much of the same characteristics seen at normal shooting distances.



One thing to keep in mind, though, is the built-in lens hood. Since the front element sits so close to your subject, it’s fairly easy for the hood to cast unwanted shadows if you’re not careful.
Price Point
Priced at around USD160, the Brightin Star sits comfortably in the middle of today’s fisheye market.


It isn’t the cheapest option available, nor is it the most expensive. I will leave that decision to you because every photographer values different things. Some prioritise image quality, while others may care more about weight, build quality, or maximum aperture.
Others
Unfortunately, front filters aren’t an option due to the protruding front element.

However, Brightin Star has included a 27mm rear filter slot, allowing photographers to insert compatible rear filters whenever needed. It’s a thoughtful addition that many fisheye lenses simply don’t offer.


Another thing worth mentioning is just how incredibly wide this lens is. Be mindful of your fingers or anything else that you don’t intend to include in the photo, as they can easily sneak into the frame without you realizing it.


Who is this for?
A fisheye lens has always been a specialist tool.
It’s a niche lens designed for photographers who enjoy experimenting with unique perspectives and creative compositions.



Years ago, fisheye lenses often came with eye-watering price tags, making them difficult to justify unless you regularly shot that style of photography.
Thankfully, things have changed.
Today, you can own a capable fisheye lens for just a fraction of what they used to cost.



Whether it’s this Brightin Star or another modern fisheye within your budget, I genuinely think every photographer should own one at least once. It may not become your everyday lens, but when the occasion calls for it, nothing else can quite replicate the perspective that a fisheye offers.
Conclusion
The Brightin Star 7.5mm f2.8 IV delivers solid image quality, a compact body and a reasonable price, making it a strong option for photographers looking to explore fisheye photography.



It may not be the smallest fisheye Brightin Star has ever made; that title still belongs to the incredibly compact Brightin Star 10mm f5.6, but it strikes a nice balance between portability and optical performance.



What I appreciate most is Brightin Star’s willingness to continue developing lenses that sit outside the mainstream. While many manufacturers focus on releasing another standard autofocus prime, Brightin Star continues to experiment with unique and niche lenses, proving that they can still be highly usable by today’s standards.
I genuinely hope they continue exploring more interesting lens designs in the future.

That said… I’m still patiently waiting for their next autofocus lens since their last release.
Thank you for reading.
