Sigma 18-300mm f/3.5-6.3 DC Macro OS HSM | Contemporary - Sigma SA, Nikon F, Canon EF, Sony A, Pentax K Mount

This versatile 'all-in-one' zoom lens is designed for APS-C mirrorless and DSLR cameras, providing a massive 16.6x zoom range. It features four FLD and one SLD glass elements to manage chromatic aberration, alongside an Optical Stabiliser to reduce camera shake at longer focal lengths. Despite its wide range, it maintains a relatively compact size, making it a popular choice for travel and general-purpose photography. Check the zoom barrel for 'zoom creep' when the lens is pointed downwards, though it does feature a lock switch to prevent this. Ensure the Optical Stabiliser engages smoothly without vibrating the image. SDS examines the front and rear elements for any coating damage and tests the HSM motor to ensure it achieves focus quickly at both the wide and telephoto ends.
