AstrHori 2-5x Ultra Macro 25mm f/2.8

The AstrHori 2-5x Ultra Macro 25mm F2.8 is a manual focus macro lens that delivers 2x to 5x magnification for around $249 USD. It's the cheapest way to get into ultra macro photography, with best-in-class macro performance and surprisingly good bokeh. But it can't focus to infinity, has no autofocus, and suffers from light leak issues in bright conditions.

In our database, this lens ranks at the 100th percentile for macro performance. That's the absolute best right now, which makes sense given the 5x maximum magnification. Most dedicated macro lenses top out at 1x, and even the fancy ones rarely go past 2x. The AstrHori starts at 2x. The working distance is tight, around 37.5mm to 45mm depending on magnification, so you'll be right on top of your subject. That makes lighting tricky, but the short focal length helps with depth of field compared to longer macro lenses at the same magnification.

Optically, it's a mixed bag. The 10 elements in 7 groups include 2 ED elements, which helps with chromatic aberration, but the overall optical score sits at the 52nd percentile. Middle of the pack. Bokeh is a standout at the 89th percentile, helped by the 8-blade aperture. The f/2.8 max aperture is also strong for this class. But there's a real weakness: light leak and flare. One owner reported significant flare when shooting in sunlight, which is a problem for a lens that needs a lot of light to work at 5x magnification. You'll want a flash or LED panel, and probably a lens hood or some DIY baffling.

The obvious comparison is the Laowa 25mm f/2.8 2.5-5x Ultra Macro. Both lenses share the same focal length, similar aperture, and the same 2x to 5x magnification range. The Laowa costs more, around $399 USD, but it has a better reputation for build quality and optical consistency. The AstrHori undercuts it by about $150 USD, which is a lot of money for a hobbyist. But you're rolling the dice on quality control.

If you want a more versatile macro lens, the Tamron Di III VC 28-300mm f/4-7.1 or the Sigma Contemporary 18-50mm f/2.8 DC DN are completely different animals. Those are general-purpose zooms with some close-focus ability, not dedicated macro tools. They can't touch 2x magnification, let alone 5x. But they can focus to infinity, autofocus, and shoot portraits or landscapes. The AstrHori is a one-trick pony, and it's very good at that one trick. Just don't expect it to do anything else.

At $249 USD, the AstrHori 25mm F2.8 is one of the cheapest ultra macro lenses you can buy new. The Laowa 25mm f/2.8 2.5-5x Ultra Macro, which this lens is clearly inspired by, costs around $399 USD. That's a significant savings for a very similar concept. The trade-off is build quality and optical consistency. AstrHori is a budget brand, and the 3.5/5 customer rating with only 7 reviews suggests quality control can be hit or miss. If you're on a tight budget and want to experiment with 5x macro, this is a reasonable gamble. If you need reliability for paid work, the Laowa is probably worth the extra cash.

The AstrHori 2-5x Ultra Macro 25mm F2.8 is a weird little lens, and I mean that as a compliment. It's a manual focus prime built for one thing: getting absurdly close to tiny subjects. We're talking 2x to 5x magnification, which puts it in a category most photographers never touch. At around $249 USD, it's also one of the cheapest ways to get into ultra macro photography without buying a microscope objective and a pile of adapters.

This is a Fujifilm X mount lens with full-frame coverage, though the marketing copy gets a little confused about that. Fuji X cameras are APS-C, not full-frame, but the lens projects an image circle big enough for full-frame sensors. That's handy if you ever adapt it to something else. The 25mm focal length and f/2.8 aperture are fixed, and there's no focus ring at all. Just a magnification ring. That's not a typo. You set magnification from 2x to 5x and move the whole camera to find focus.

Is the AstrHori 25mm good for regular photography? No. It can't focus to infinity. It's a macro-only tool, and a specialized one at that. But for people who want to photograph insect eyes, snowflakes, or the texture of a dollar bill, it's a fascinating option at a price that doesn't require selling a kidney.

Skip this lens if you're new to macro photography or want a versatile lens. The AstrHori 25mm F2.8 is a specialized tool for extreme close-up work, and it's frustrating to use if you don't have experience with focus stacking, flash lighting, and manual focus technique. If you want a general-purpose macro lens that can also do portraits or product shots, look at a 90mm or 100mm macro with 1x magnification. If you need autofocus, this lens is a non-starter. And if you shoot outdoors in bright sunlight without a flash, the light leak issue will drive you crazy. The Laowa 25mm f/2.8 2.5-5x is a safer bet if you can stretch your budget.

Should you buy the AstrHori 2-5x Ultra Macro 25mm F2.8? If you're a macro enthusiast who wants to explore 2x to 5x magnification without spending Laowa money, yes. It's a specialized tool that delivers best-in-class macro performance for the price. The 25mm focal length gives you more depth of field than longer macro lenses, which means fewer frames for focus stacking. That's a real practical advantage.

But this is not a lens for everyone. It can't focus to infinity, it has no autofocus, and the build quality is nothing to write home about. The light leak issue in sunlight is a genuine problem that will frustrate you if you shoot outdoors without a flash. If you're new to macro, start with a 1x macro lens like the Sigma 18-50mm f/2.8 or a dedicated 90mm macro. This AstrHori is for people who already know they need 5x magnification and are willing to work around its quirks.
