The Tamron 10-24mm Di II provides a wide-to-standard zoom for APS-C Sony DSLR photography, useful for landscape, architecture, and environmental work. The Sony A mount version is compatible with Sony Alpha DSLR bodies (A77, A580, A380, etc.). The Di II coverage means it will vignette heavily on Sony A-mount full-frame cameras.
Inspect for fungus, haze, and coating condition. Test at 10mm for distortion. Confirm Sony A mount engagement. Check AF function on a compatible Sony Alpha DSLR. Test at wide and telephoto extremes for sharpness.
