Tamron's extended superzoom for Sony A — the 18-250mm covering 27-375mm equivalent on APS-C.
The Tamron AF 18-250mm f/3.5-6.3 Di II LD Aspherical IF Macro is an extended superzoom for Sony A-mount APS-C cameras. Covering a 27-375mm equivalent range, it pushed the boundaries of all-in-one zoom convenience when released in 2006. The LD and aspherical elements help manage the optical compromises of a 14x zoom ratio.
Optical performance involves the expected superzoom compromises amplified by the extended zoom ratio. Centre sharpness is acceptable at moderate focal lengths. The IF (Internal Focusing) prevents front element rotation. LD elements provide better chromatic correction than basic alternatives. Adequate for casual travel photography where convenience is the absolute priority.
Sony A mount, APS-C only (Di II). Filter thread is 62mm. Weight is approximately 430 grams — impressive for the range. Build quality is functional plastic. Benefits from Sony's SteadyShot INSIDE body stabilisation. No in-lens stabilisation. The extended 250mm telephoto end provides genuinely useful reach for casual wildlife and sports.
Very cheap on the used market given declining A-mount demand. Check for zoom creep and smooth AF. The A-mount compatibility includes adaptability to E-mount via LA-EA adapters. A basic travel convenience lens — the optical quality does not compare to dedicated zooms but the range is genuinely impressive in a single package.
