Tamron's early APS-C superzoom with macro capability — 27-300mm equivalent range for Nikon DX shooters.
The Tamron 18-200mm f/3.5-6.3 XR Di II LD Aspherical (IF) Macro launched around 2005 as one of the earlier APS-C superzooms. Covering 27-300mm equivalent on Nikon DX, it offered an impressive all-in-one range for travel and general photography.
Optical quality is modest — centre sharpness is acceptable but the edges are soft, particularly at longer focal lengths. No stabilisation on this version, which makes handheld shooting at 200mm challenging. The internal focusing design keeps the barrel length constant during zoom.
Nikon F mount, APS-C coverage. 62mm filter thread. Approximately 398g. No weather sealing. LD (Low Dispersion) and aspherical elements help control aberrations. XR (Extra Refractive) glass enables the compact design. Macro mode focuses to 45cm with 1:3.7 ratio.
Very cheap used. Superseded by the VC versions which added stabilisation — a major improvement. Only worthwhile if budget is the primary concern. The Nikon 18-200mm VR is the better choice in most cases. Check for zoom creep — a common issue on older superzooms.
