The Olympus Zuiko 24mm f/2.8 is a compact, manual-focus wide-angle lens designed for the Olympus OM system. With a diagonal angle of view of 84°, it offers a broader perspective than standard 35mm lenses, making it ideal for landscapes, street photography, and environmental portraits. 

Weighing approximately 180 grams and measuring just 31mm in length, this lens is exceptionally portable. Its optical construction consists of 8 elements in 7 groups, and it features a 6-blade aperture diaphragm. The lens accepts 49mm filters and focuses as close as 0.25 meters, allowing for versatile shooting scenarios. 

While the lens performs well across various apertures, it exhibits some softness and vignetting at f/2.8, which improves significantly when stopped down to f/8 or f/11.  Its compact size and solid build quality make it a valuable addition to any photographer’s kit, especially for those seeking a reliable wide-angle lens for both film and adapted digital use.
