Sony's compact APS-C macro for A-mount — 45mm equiv with 1:1 magnification and SAM motor.
The Sony DT 30mm f/2.8 Macro SAM is a compact macro prime for Sony A-mount APS-C cameras, providing 45mm equivalent with true 1:1 magnification. The SAM motor enables AF on all A-mount bodies including those without screw-drive.
Optically good at macro distances — sharp with the 45mm equivalent providing moderate working distance. The SAM motor is an improvement over body-driven AF for macro — more precise. Also functions as a compact normal prime.
Sony A-mount with 49mm filter thread. Just 150g — incredibly compact for a 1:1 macro. DT — APS-C coverage. SAM built-in motor. No weather sealing. Minimum focus distance approximately 12.9cm at 1:1. In-body SteadyShot helps.
Available used very cheaply. A-mount is discontinued. The very close working distance at 1:1 means the lens is almost touching the subject. For A-mount users wanting budget macro with built-in AF motor. The compact size is a real plus.
