AstrHori
The 9mm focal length delivers a 111.4° angle of view and the f/2.8 aperture gathers enough light for clean starry sky shots with controlled noise. Its 7-blade aperture creates distinctive 14-point starbursts from point light sources, while the 20cm minimum focus distance enables exaggerated, impactful close-up portraits. This manual lens is best for astrophotography hobbyists and creative portrait shooters on Micro Four Thirds who prioritize dramatic perspective over autofocus convenience.
Resumen
The 30-Second Version
A beautifully built, all-manual ultra-wide that's a blast for creative starbursts and close-ups, but it's let down by soft optics and a shocking number of unhappy owners. It's a niche toy for tinkerers, not a reliable tool for serious work.
Pros & Cons
Ventajas
- All-metal build feels way more expensive than it is 84th
- Insanely fun 14-point starburst effect when stopped down 75th
- Super close 20cm minimum focus for creative wide-angle macros
- Tiny and light, a perfect toss-in-your-bag lens
Desventajas
- Manual focus only, and no electronic contacts to pass EXIF data
- Edge sharpness is pretty rough, especially wide open
- Customer satisfaction is alarmingly low based on early reviews
- f/2.8 isn't truly fast when you factor in the softness

Performance
What surprised us most is how much fun the close-up performance can be. The 20cm minimum focus distance combined with the 9mm field of view lets you get right up in a subject's face for some wildly distorted, expressive portraits. It's not clinically sharp wide open, and you'll see some softness at the edges, but the center holds up well enough for striking social media shots. The real party trick is stopping down to f/8 or f/11, where point light sources turn into those crisp 14-spike starbursts. It's a genuinely cool effect that makes night cityscapes pop.

vs Competition
Stacked against a kit zoom like the Nikon NIKKOR Z DX 16-50mm f/3.5-6.3 VR, the AstrHori is a one-trick pony. The Nikon gives you autofocus, stabilization, and a useful zoom range, but it can't touch the AstrHori's ultra-wide 9mm field of view or its starburst rendering. The Sony E PZ 16-50mm f/3.5-5.6 OSS is in the same boat, a practical all-rounder that's boring next to this manual prime. If you need a lens that just works for everyday shooting, get the kit zoom. If you want a dedicated, weird little lens for astrophotography experiments and artistic wide-angle distortion, the AstrHori is the more interesting, if riskier, choice.

Precio
Value & Pricing
This is a tough one. The lens itself feels like a steal for the build quality and creative potential, but the price range we're seeing is absolute chaos, spanning from $149 to a completely nonsensical $29,333. Ignore the crazy high listing, it's clearly an error. At the real-world price around $150, it's a fun toy for experimenters. Just know that the abysmal 1.4-star average from owners suggests a serious disconnect between the spec sheet and real-world happiness. Proceed with caution.

Overview
The AstrHori MF 9mm f/2.8 is a quirky little ultra-wide prime that promises a lot of creative fun for not a lot of cash. It's a fully manual, all-metal lens built for APS-C mirrorless cameras, and the one thing you need to know is that it's a specialty tool, not a daily driver. If you want to play with dramatic perspectives, 14-point sunstars, and don't mind wrestling with manual focus, this lens delivers a unique look that's hard to find elsewhere at this price. But if you're expecting sharp corners and modern conveniences, you're looking in the wrong place.
Common Questions
Q: Does this lens have autofocus?
Nope, it's fully manual focus only. There are no electronic contacts at all, so your camera won't even record the aperture or lens name in the photo's data.
Q: Will this work on my full-frame Nikon Z camera?
It will mount and work, but it's designed for APS-C sensors. On a full-frame body like a Z6 or Z7, you'll get heavy black vignetting around the image circle, so you'll need to shoot in DX crop mode.
Q: Is this lens good for astrophotography?
On paper, the 9mm focal length and f/2.8 aperture seem ideal for Milky Way shots. In practice, you'll likely need to stop down to f/4 to get acceptable corner sharpness, which defeats the purpose of the fast aperture. It can work, but it's not the low-light hero the specs suggest.
Who Should Skip This
If you need a reliable, sharp lens for everyday video or stills, this isn't it. The lack of autofocus and soft edges will drive you nuts. Go get a used Nikon Z DX 16-50mm VR or a Sony 16-50mm OSS instead. They're stabilized, sharp, and won't make you miss a shot while you're fiddling with a focus ring.
Verdict
The AstrHori 9mm f/2.8 is a hard lens to recommend to most people. It's beautifully built and capable of genuinely unique images, but the manual focus, soft edges, and terrible user reviews paint a picture of a lens that frustrates more than it delights. Buy it only if you know exactly what you're getting into and you're willing to work for the shot. For everyone else, save up for a used ultra-wide zoom with autofocus.
