The lightest and thinnest lens in the EF-S series for APS-C sensor cameras, the EF-S24mm f/2.8 STM is a pancake lens measuring 22.8mm in thickness (about a third in thickness in comparison to a kit lens) and weighing only 125g (approximately the same weight as a smart phone). The 24mm (35mm equivalent) focal length grants the EF-S24mm f/2.8 STM a natural wide angle view, making it highly versatile for capturing everyday scenes involving pets, food, friends, and environments. Its short minimum focusing distance of 0.16m and maximum magnification of 0.27x also makes it ideal for food photography and capturing small details. As the EF-S24mm f/2.8 STM operates on a quiet STM mechanism, audio quality of movies remains unaffected with the absence of noise from lens during the focusing process.
