Tamron's APS-C superzoom for Sony A — the 18-200mm Di II for travel convenience.
The Tamron AF 18-200mm f/3.5-6.3 XR Di II LD ASPH Macro for Sony A is the Sony A-mount version of Tamron's popular superzoom described across IDs 3439, 3566, and 3725. Covering 27-300mm equivalent. The A-mount version benefits from Sony SteadyShot body stabilisation — an advantage over other mount versions.
Same superzoom optics as all other mount versions. Centre sharpness acceptable at moderate focal lengths. Variable aperture. The Sony body SR provides stabilisation absent from the lens itself — a genuine practical advantage over other mount versions. XR and LD elements control aberrations. Macro close-focus adds versatility.
Sony A mount, APS-C. Filter thread 62mm. Weight approximately 398 grams. Same optical design as other mount versions. Benefits from Sony body SR stabilisation. A-mount is discontinued but adapts to E-mount via LA-EA adapters. The body SR is the unique advantage of the A-mount version.
Very cheap given A-mount decline. Same lens as other mount versions with Sony SR advantage. Check zoom creep and AF. The body SR compensates for no lens IS. Adequate for travel convenience. Adapts to E-mount via LA-EA5. The declining A-mount demand creates very good pricing.
