What Buyers Say
Rokinon HD 8mm f/3.5 HD Fisheye 8mm
This Rokinon 8mm f/3.5 fisheye lens is praised for its excellent value, solid build, and creative potential, especially on APS-C cameras where it delivers a full-frame diagonal fisheye effect. Users love the fun perspective it adds to landscapes, portraits, and skateboarding or astro shots, though they note it requires manual focus and aperture control. Some edge softness and chromatic aberration are mentioned, but these are correctable in post. Issues with full-frame cameras (heavy vignette) and inconsistent compatibility with certain Nikon bodies (e.g., D3500) are recurring drawbacks, and a few users reported a broken focusing ring or cheap-feeling barrel.
Pros
- Great value for money
- Solid build quality
- Fun and creative perspective
- Sharp when stopped down (f/5.6-f/8)
- Lightweight and compact
Cons
- Manual focus only
- Soft edges wide open
- Chromatic aberration at edges
- Not ideal for full-frame cameras (heavy vignette)
- Incompatible with some Nikon bodies (e.g., D3500)
