Sony FE 100mm f/2.8 STF GM OSS - Sony E-mount

This specialised short-telephoto prime features a built-in apodisation (APD) element designed to produce exceptionally smooth bokeh. It includes Optical SteadyShot stabilisation and a Direct Drive SSM motor for quiet focusing. Note that the APD element reduces light transmission, resulting in a T5.6 rating at the widest aperture of f/2.8, making it primarily a lens for portraiture in controlled lighting. Check the APD element for any internal haze or dust which could disrupt the specific bokeh characteristics. SDS verifies the OSS system is silent and effective, and that the macro switching ring rotates smoothly. We also inspect the filter thread and bayonet mount for signs of heavy wear, ensuring the specialised optical path remains clear and properly aligned.
