Olympus Zuiko Digital ED 18-180mm f/3.5-6.3 - Four Thirds Mount

The Zuiko Digital ED 18-180mm f/3.5-6.3 is an all-in-one 'superzoom' lens designed for the Four Thirds DSLR system. Covering a focal range equivalent to 36-360mm in 35mm terms, it is intended as a single-lens solution for travel and general-purpose photography. It incorporates Extra-low Dispersion (ED) glass elements to minimize chromatic aberrations, which is particularly useful at the longer end of the zoom range. As a complex zoom, the mechanical movement should be tested for consistency across the entire range. SDS checks the electronic contacts for reliable communication with the camera body and ensures the autofocus motor operates correctly. Due to the high number of moving parts, the lens is checked for internal dust and any signs of impact damage that might affect optical alignment.
