Samyang 24mm f/1.4 ED AS IF UMC

This manual focus wide-angle lens is designed for full-frame cameras, featuring a fast f/1.4 maximum aperture. The optical construction uses two aspherical and two extra-low dispersion (ED) elements to minimise chromatic aberrations and distortion. It uses an internal focusing (IF) system, meaning the lens does not change length during use, and features UMC multi-coating to reduce flare and ghosting in challenging lighting conditions. When purchasing used, pay close attention to the manual focus action; it should be damp and smooth without any grinding or loose points. The aperture ring should click cleanly at each stop. SDS checks for signs of heavy professional use, such as wear on the mount or barrel, and performs a thorough optical inspection to ensure there is no internal element misalignment or coating damage.
