Rokinon Series II 85mm f/1.4 85mm
The Rokinon 85mm f/1.4 manual lens offers exceptional value for astrophotography and portrait work, delivering sharp images and smooth bokeh at a fraction of the cost of autofocus equivalents. Users praise its center sharpness wide open and excellent performance when stopped down to f/2.8, especially for capturing stars. However, the purely manual focus and aperture can be fiddly, and build quality inconsistencies like a missing hood or accidental aperture ring bumps are noted. Overall, it's a highly recommended budget lens for those comfortable with manual operation.

- Smooth bokeh
- Excellent for astrophotography
- Great value for money
- Solid build quality
