Sony 70-300mm f/4.5-5.6 G SSM - Sony A-mount

This G-series telephoto zoom for A-mount cameras features a Super Sonic wave Motor (SSM) for quiet and responsive autofocus. The optical path includes Extra-low Dispersion (ED) glass to reduce chromatic aberrations across the 70-300mm range. It is built to a high standard, suitable for wildlife and sports photography, and is compatible with both full-frame and APS-C Sony DSLRs or SLT cameras. Check for smooth movement of the zoom ring, as these units can become stiff over time. The SSM motor should operate silently; any high-pitched whining may indicate impending failure. SDS checks the internal optics for fungus and ensures the focus hold button and focus range limiter switch function correctly. We also verify the condition of the rubber grips, which can sometimes become loose with heavy use.
