The Brightin Star 35mm F1.8 lens offers good build quality and features like a clickless aperture ring, priced at $216. It performs well in sharpness (very good wide open and excellent as of F2.8), with good color rendition and low chromatic aberration. However, it struggles with background blur softness, corner sharpness, vignetting. Alternatives for better performance exist but at a much higher price.
