What Buyers Say
Brightin Star AF 12mm f/2.8 12mm
The Brightin Star 35mm f/0.95 manual lens is praised for its exceptional sharpness, fast aperture, and build quality, especially given its budget-friendly price. However, some users note it's a specialty lens requiring practice for manual focus, and at least one reviewer reported compatibility issues with certain Canon EOS R7 firmware. The Sony 70-200mm f/2.8 GM II lens receives high marks for sharpness and fast autofocus, but several Q&A posts raise concerns about internal movement when the camera is off. Overall, sentiment is very positive for both lenses, with a few isolated negatives.
Pros
- Excellent sharpness
- Fast f/0.95 aperture
- Affordable price
- Solid build quality
- Beautiful bokeh
Cons
- Manual focus requires practice
- No autofocus
- Potential compatibility issues with Canon R7 firmware
- Specialty lens not for beginners
- Heavy all-metal construction
