Sony G SEL40F25G 40mm
Combining a 40mm focal length with a featherlight 173g build, this full-frame prime delivers G-series sharpness through three aspherical elements and one ED element. Its dust and moisture-resistant construction and de-clickable aperture ring offer tactile, professional-grade control in a package small enough for any bag. This lens is best for travel and street photographers who prioritize a discreet, all-day carry with a natural field of view.
