7Artisans 10mm f/2.5 Fisheye review: A fast, affordable, autofocus fisheye with weather sealing for Sony, Nikon and L-Mount

I still can't quite believe the 7Artisans 10mm f/2.5 Fisheye lens. What it offers – and, more importantly, delivers – for the price is pretty remarkable.

You get an eye-watering 185° angle of view, for starters, which is a reality-warping kind of perspective. And you get a fast f/2.5 aperture, which obviously is far more useful for low light than blurry backgrounds at this focal length. But you also get an enviable 0.15m close focus distance, full weather sealing and, best of all, autofocus.

This, in case you're unaware, is almost unicorn territory for a fisheye lens; there is, after all, only one other autofocus fisheye for the Sony E and L-Mount (from Sigma), and none whatsoever for Nikon Z cameras. But the 7Artisans 10mm f/2.5 Fisheye offers all this for under $500 – less than a quarter of the price of the alternative.

Fisheye lenses aren't for everyone, and they aren't for everything, but they're a brilliant creative addition to your arsenal – and if I were in the market for one, with its unique combination of price, performance and size, the 7Artisans 10mm f/2.5 Fisheye is the one I would personally purchase. Here's why.

7Artisans AF 10mm f/2.5 Fisheye: Price & availability

The 7Artisans 10mm f/2.5 Fisheye was launched in September 2026 with a price tag of $449 – which translates to around £330 / AU$625.

While there are plenty of third-party manual options, as noted there are almost no autofocus alternatives native to the E, Z or L-Mount – and none at all for Nikon's mirrorless platform.

For Sony and L-Mount cameras, there is the Sigma 15mm f/1.4 DG DN | Art Fisheye prime, priced $1,999 / £1,859 / AU$3,795, which is faster but wider.

Other than that, Sony shooters have the option of a slower autofocus zoom – the Sony FE 8-14mm f/3.5 Fisheye G, which carries a $1,599 / £1,499 / AU$2,099 asking price.

7Artisans AF 10mm f/2.5 Fisheye: Build & handling

Despite its affordable price point, the 7Artisans 10mm f/2.5 Fisheye feels every inch a premium lens – and indeed, it's part of the company's Max line of top-tier optics. The all-metal construction gives it a satisfying amount of heft in the hand, and obviously offers a reassuring level of robustness. On top of that, it's finished beautifully with a pleasingly smooth, satin finish that suggests a far more expensive optic.

The mount (which, again, is metal) features a USB-C connection for easy firmware updates and is finished with a gasket – making this is a weather-sealed lens that you can take out even in challenging conditions. As always, remember that this is only true if your camera is likewise sealed (which my Lumix S9 is not!) so make sure your body and lens are weather-sealed before shooting in wet or dusty conditions.

Despite its build quality, the 7Artisans 10mm f/2.5 Fisheye is comfortably light at 504g and pretty small at just 94mm in length – which makes it a smart match for smaller full-frame bodies like the Lumix S9 and Sony A7C II, as well as Sony's APS-C cameras. This stands in stark contrast to the Sigma 15mm f/1.4 DG DN | Art Fisheye, which tips the scale at 1,400g and measures 160mm.

Given the bulbous nature of the front element, this lens has a fixed hood on the front – which serves both to protect the glass and shield the optic from errant light sources. This does mean, of course, that it's not compatible with traditional lens filters – so you're looking at sensor-mounted options if you want to use something like an ND filter.

I'll also point out that, despite the integrated hood, the front element remains very vulnerable – especially if, like me, you whip it in and out of a sling bag for street shooting. You should definitely use the supplied lens cap (which is felt-lined and slides on top of the hood petals) whenever you aren't actively shooting, as you don't want to smudge, ding or damage that exposed element.

Where controls are concerned, there's an aperture ring (clicked) for lens-based exposure control as well as a very nice manual focus ring (fly-by-wire) if you want to override the AF. To accomplish this there's a manual / autofocus switch, and a pair of function buttons enable you to map custom controls to the lens.

7Artisans AF 10mm f/2.5 Fisheye: Compatibility

It's important to note that the 7Artisans 10mm f/2.5 Fisheye isn't fully compatible with every Sony or Sigma camera body (all current Nikon and Panasonic cameras will work fine).

The manufacturer has provided a list of camera compatibility, as of September 2026. Per 7Artisans, 'Fully compatible' means that all functions work, 'Basically compatible' means "normal shooting works; some features are being improved" and 'Not compatible' means that the lens cannot be used.

Here's the full list:

7Artisans AF 10mm f/2.5 Fisheye: Performance

I primarily tested the 7Artisans 10mm f/2.5 Fisheye with my Lumix S9. I shot in a variety of conditions and situations, from action skateboarding and portraiture to architecture and close-ups to day and night street photography.

As noted in the specs, and evidenced by the sample images below, this is a 'full frame' or 'diagonal' fisheye lens. In other words, it captures images that fill the entire image area, from corner to corner, rather than being a 'circular' fisheye lens that captures a porthole-style image surrounded by a black frame.

Shooting with a fisheye lens is always a good time, but I didn't previously own a fisheye quite as wide as this. So the first thing I wanted to shoot was street skateboarding – which, as anyone who grew up in the Nineties watching the likes of Rodney Mullen, Chad Muska and Bam Margera tear, is the preserve of low-angle fisheye shots.

The 10mm focal length definitely added an element of challenge, as you have to get right up close to the action (or ask the skater to bring the action right up close to you) which invites a little bit of danger! But I absolutely love the results and especially the environmental results that are possible.

Even though the Lumix S9 still doesn't have Panasonic's skateboard autofocus, the 7Artisans 10mm f/2.5 Fisheye was able to keep up with the action whenever the camera could – and it never once dropped focus once it had been acquired, which is pretty impressive.

Just as impressive is the lens' control of flare and glare. We shot at a variety of angles from the sun, including with it right behind us, and I only managed to capture a single instance of flare (and that's shooting 30fps bursts!) which you can see above.

I also took advantage of having a great subject on hand to capture some portraits. This isn't necessarily the first thing you should do with a fisheye lens, but it's possible to get some creative people pictures with a very unique perspective.

Obviously I wasn't able to get any meaningful subject separation, given the wide-angle nature of the lens, though you can use the 0.15m close-focusing capability to achieve background blur by getting right up to your subject. As you can see in the samples below, I was able to get a pretty pleasing macro-esque shot of a tiny bug on a flower.

Bokeh, as and when you achieve it, isn't anything to write home about; it's quite busy, and often descends into smear rather than blur thanks to field curvature, but I don't realistically think anyone is buying this lens for creamy backgrounds!

Where I was really impressed with the 7Artisans 10mm f/2.5 Fisheye is sharpness. Again due to the curvature of the front element, we weren't able to adequately lab test this lens; it's simply too bulbous to get any worthwhile test data as soon as you start moving away from the center.

But as you'll see in the above close-up image of fruit, and in the flora images below, center sharpness really is very good – and even as you stray towards the edges of the frame, where things will inherently be weaker, things can be surprisingly crisp and detailed (check out the black-and-white shots of the car park and the bicycle).

If you want to defish your images, 7Artisans has a calibration profile that you can download. This will give you more of a rectilinear look to your images, but obviously you will get superior optical performance with a native rectilinear lens.

7Artisans AF 10mm f/2.5 Fisheye: Verdict

With so many features for such a low price, I assumed that something had to give – but the 7Artisans AF 10mm f/2.5 Fisheye surprised me by delivering in every department.

The autofocus is fast and reliable, the fast aperture makes it possible to shoot when the sun is going down or gone altogether, the weather sealing keeps you shooting around water or dust, and the sharpness and overall image quality mean that your images look great – even on high-resolution sensors, as 7Artisans says that the lens can resolve 60MP, making this suitable for megapixel monsters like the Sony A7R VI.

I had a brilliant time shooting with the 7Artisans AF 10mm f/2.5 Fisheye and, even though fisheye shots aren't a huge part of my usual photography, I found myself missing this lens when I didn't have it with me – making this one of those rare lenses that genuinely impacts how you "see" the world and inspires you to pick it up and use it.

While it's a shame that the lens isn't universally compatible with all Sony and Sigma cameras,
