Sony's APS-C superzoom for A-mount — the DT 18-250mm for travel convenience.
The Sony DT 18-250mm f/3.5-6.3 is an APS-C superzoom for Sony A-mount cameras. Covering 27-375mm equivalent with SAM motor, it provides one-lens travel convenience. The DT designation confirms APS-C-only coverage. Part of Sony's A-mount lens range that provided affordable telephoto reach for their DSLR and SLT cameras.
Optical performance is typical of superzooms — acceptable at moderate focal lengths with softening at extremes. The SAM motor provides functional lens-based AF. No in-lens stabilisation — relies on Sony SteadyShot body SR. The 14x zoom ratio involves the expected optical compromises. Adequate for casual travel photography in good light.
Sony A mount, APS-C (DT). Filter thread is 62mm. Weight is approximately 445 grams. Build quality is functional consumer grade. Benefits from Sony body-based stabilisation. The SAM motor provides quieter AF than body screw-drive. The A-mount system is discontinued.
Very cheap on the used market. Check zoom mechanism and AF. A basic travel superzoom for Sony A-mount. The A-mount decline keeps prices very low. Adapts to E-mount via LA-EA adapters. Adequate for casual use where convenience outweighs optical quality.
