ASTRHORI AstrHori 6mm F2.8 Full Frame Circular Fisheye Review
The AstrHori 6mm F2.8 delivers an insane 220-degree circular fisheye view for wild creative shots. Just don't expect it to be sharp or versatile.
Overview
The AstrHori 6mm F2.8 is a wild lens. It's a full-frame circular fisheye that gives you a 220-degree field of view. That means your photos are a perfect circle, with the world wrapped around the edges like you're looking through a peephole. This isn't your everyday lens. It's a specialized tool for creating extreme, distorted perspectives that you can't get any other way. Think of it as your ticket to shooting the entire night sky in one go, or cramming an entire skate park into a single, warped frame.
Performance
The performance is exactly what you'd expect from a lens this weird. The 220-degree view is the main event, and it delivers that crazy circular look perfectly. The f/2.8 aperture is decent for a fisheye, letting you shoot in lower light. But let's be real, the optical quality is just okay, landing in the 34th percentile. You get heavy distortion and softness at the edges, which is part of the charm, but don't expect tack-sharp detail across the frame. The close-focus ability is a fun bonus for super warped close-ups.

Value & Pricing
At around $299, the value is all about the specific look. You're not paying for flawless optics or fancy features. You're paying for access to that 220-degree circular view, which is genuinely unique at this price. If that's the exact effect you need, it's a bargain. If you want a sharp, versatile lens, look elsewhere because this money only buys one very specific trick.
vs Competition
This lens doesn't really compete with normal ones like the Viltrox 35mm f/1.7 or Meike 55mm f/1.8. Those are sharp, fast primes for everyday shooting. The AstrHori is the opposite. It's for when those lenses are too boring. The real comparison is to other fisheyes or ultra-wide lenses. Against those, its main draw is the extreme 220-degree angle. You trade optical perfection and autofocus for a more intense, circular fisheye effect than most others offer.

Verdict
Buy this lens if you're a creative photographer or videographer who knows exactly what a circular fisheye can do and you want the most extreme version of it. It's perfect for experimental art, unique real estate shots, or capturing the entire night sky. Do not buy this as your only lens, or if you expect clean, sharp images. It's a specialty tool for a very specific job.
