Tamron AF 18-200mm f/3.5-6.3 XR Di II LD Aspherical (IF) Macro

The Tamron AF 18-200mm f/3.5-6.3 XR Di II LD Aspherical (IF) Macro is an all-in-one zoom lens specifically designed for APS-C digital SLR cameras. It utilizes Extra Refractive (XR) glass and Low Dispersion (LD) elements to maintain a compact form factor while minimizing chromatic aberrations. The 'Di II' designation indicates it is optimized for digital sensors, and the internal focusing (IF) system ensures the front element does not rotate, facilitating the use of circular polarising filters. When buying a used 18-200mm, check the autofocus motor for quiet and responsive operation. SDS inspects the zoom mechanism for any uneven resistance, a common trait in high-ratio zooms. The external barrel is largely plastic, so we check for impact damage or cracks. We also verify the condition of the rear mount contacts to ensure consistent communication with the camera body, and check for internal dust which can be drawn in during zooming.
