The 30-Second Version
You're buying this for the 2:1 macro magnification, which is the real deal and pairs with optical performance in the 82nd percentile. The built-in ring light helps offset the slow f/13 aperture, but manual focus and no stabilization mean you'll be tripod-bound. Build quality is a letdown at the 11th percentile, and prices are all over the map from $739 to $1398, so shop carefully.
Overview
The AstrHori 28mm f/13 2x Macro Probe is a lens that does one thing, and mostly does it well: capturing hugely magnified, bug-eye close-ups that standard macro lenses can't touch. With a true 2:1 reproduction ratio and a long, skinny barrel that slips into tight spaces, it's a specialist's tool first and foremost. Our test numbers put its optical quality in the 82nd percentile, which means it's well above average for sharpness and clarity, especially considering the price. But that's where the party mostly ends. The build quality is a real weak point, landing in just the 11th percentile, and the fixed f/13 aperture is as slow as it gets.
You get a built-in ring light powered by USB-C, a waterproof front section, and swappable 0-degree and 90-degree view modules that add some creative flexibility. Manual focus is the name of the game here, and there's no stabilization, so you'll want a tripod and some patience. The lens is available for Canon RF, Sony E, Nikon Z, L-Mount, and Fujifilm X, which is a nice touch. Still, with prices swinging from $739 all the way up to $1398, it's not an impulse buy, and you really have to need this specific kind of macro perspective to make the investment worthwhile.
Performance
This lens is a data nerd's delight when you look at macro numbers. Our macro score of 67.5 out of 100 doesn't sound earth-shattering, but that's enough to land in the 76th percentile across all lenses, making it a strong contender for dedicated close-up work. The 2:1 magnification is the headline act, letting you fill the frame with details the size of a grain of rice. Working distance is a minuscule 0.31 inches from the front element, and the lens barrel gets you right into the action while keeping the camera body comfortably far away. Optical sharpness is where this lens punches above its weight, earning that 82nd percentile ranking. Our test shots showed crisp detail at the center, though the fixed f/13 aperture means you'll be living at high ISOs or relying heavily on that integrated ring light.
Don't expect artful bokeh, the 7-blade diaphragm and slow aperture keep background blur in the mediocre 33rd percentile, so this is all about the subject, not the background. The lens is manual focus only, which is typical for macro probes and honestly where you'd be anyway at this magnification, but it also lacks any image stabilization, so handheld shooting is a shaky affair. The ring light is a genuine helper, casting even illumination right where you need it, but its output is modest. For serious work, plan on adding external lighting. If you can lock everything down on a tripod and dial in focus carefully, the AstrHori will deliver detail-rich images that are hard to get any other way.

Value & Pricing
Value depends entirely on how much you pay. Across retailers, we've seen prices as low as $739 and as high as $1398. At the lower end, you're getting a unique macro tool for less than many standard macro lenses, and the 2:1 magnification alone is a big draw. But once you cross that $1,000 line, the value proposition crumbles. For the same money, you could grab a competent traditional macro lens with autofocus and better build, then rig up extension tubes or a bellows for similar magnification. This lens is a specialty buy, and if you can snag one for that $700-$800 sweet spot, it's worth it for the unique perspective. Spend much more, and you're paying a hefty premium for a lens that feels decidedly budget in hand.
vs Competition
Stacked against the usual suspects, the AstrHori 28mm f/13 is an oddball. The Canon RF 28-70mm f/2.8 IS STM, for instance, is a versatile zoom with a fast aperture, superb autofocus, and weather sealing, but it can't touch 2:1 macro. The Nikon Z 18-140mm and Sigma 10-18mm f/2.8 are general-purpose wide zooms that would run circles around the AstrHori for travel and everyday shooting. Even the Viltrox AF 9mm f/2.8 offers autofocus and a bright aperture at a fraction of the price, though again, no macro. The AstrHori's only real advantage is that probe form factor and extreme close-focus ability. If you need that specific tool for wildlife videography, product detail work, or creative niche photography, none of the rivals can replicate it. But if you only occasionally dabble in macro, any of the other lenses will serve you far better day to day.

Common Questions
Q: Does this lens have autofocus?
No, it's manual focus only, which is pretty typical for macro probe lenses. You'll be fine-tuning focus by hand, which is actually preferred for extreme close-up work. Our macro tests placed it in the 76th percentile, so the manual focus ring gets the job done.
Q: How good is the image quality?
Optical performance sits in the 82nd percentile, well above average. The lens is sharp enough for professional macro work, especially when you stop down a bit (though f/13 is already pretty stopped down). Just don't expect creamy bokeh, the background blur ranks in a mediocre 33rd percentile.
Q: Can I use this as a regular walkaround lens?
Not really. The fixed f/13 aperture is slow, and the lens is manual focus with no stabilization, which makes it impractical for everyday stuff like portraits or landscapes. Our versatility score was a low 35th percentile, so stick to macro and creative probe shots.
Who Should Skip This
If you need a lens that can handle more than macro, this isn't it. The fixed f/13 aperture, manual focus, and zero stabilization make it a liability for travel, events, or any kind of run-and-gun shooting. Versatility lands at just the 35th percentile, meaning it's far below average for general use. And with build quality scraping the bottom at the 11th percentile, this lens won't stand up to rough handling. If you're only a casual macro shooter or want a lens that can pull double duty, your money is better spent on a standard macro like a 105mm f/2.8 with extension tubes.
Verdict
The AstrHori 28mm f/13 is a one-trick pony, but it's a pretty neat trick if you're into extreme macro. It delivers 2:1 magnification and above-average image quality in a package that lets you get shots no other lens can reach. However, the slow aperture, manual focus, complete lack of stabilization, and questionable build quality hold it back from being a must-have. It's strictly for dedicated macro shooters who understand and accept its limitations. If you're looking for a versatile walkaround lens, move along. If you've been lusting after that probe-style macro look and can find it for under $800, it might just earn a spot in your bag.
