What Buyers Say
Sigma Contemporary 10-18mm f/2.8 DC DN
The Sigma 10-18mm f/2.8 DC DN Contemporary lens is highly praised for its compact, lightweight design and sharp image quality, making it an excellent choice for travel and real estate photography on APS-C cameras. Users appreciate the fast f/2.8 aperture for low-light performance and pleasing background blur, though some note the lack of in-lens stabilization and the need for post-production correction of distortion and vignetting on certain camera systems.
Pros
- Compact and lightweight design
- Sharp image quality across frame
- Fast f/2.8 constant aperture
- Excellent for travel and landscapes
- Good low-light performance
Cons
- No in-lens image stabilization
- Distortion and vignetting need post-production correction

- No USB dock for firmware updates
- In-camera focus stacking not supported on Canon R7
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.

- Sharp center wide open
- Smooth bokeh
- Excellent for astrophotography
- Great value for money
- Solid build quality
Cons
- Fiddly manual aperture ring
