At 11.8oz, the GF 50mm is the smallest and lightest in the GF lens line to date. Lens construction consists of 9 elements in 6 groups and includes one aspherical lens element to minimize spherical aberration and barrel distortion. It also features a 62mm filter ring, weather-sealing in 10 places along the lens barrel and operation temperatures down to 14°F.
