Tamron 24mm f/2.8 Di III OSD M1:2 - Sony E-mount

The Tamron 24mm f/2.8 Di III OSD M1:2 is a compact wide-angle prime designed for Sony E-mount full-frame mirrorless cameras. It is notable for its 1:2 macro magnification capability, allowing for close-up photography with a minimum focusing distance of just 12cm. The lens utilizes Optimized Silent Drive (OSD) for quiet autofocus and is moisture-resistant, making it a versatile choice for street and landscape photography. Check used units for the latest firmware, as early versions sometimes exhibited slower autofocus tracking. SDS verifies the OSD motor is functioning correctly and that the weather sealing gaskets around the mount are intact. Given its lightweight plastic construction, the lens should be inspected for any cracks or stress marks on the barrel, and the front element checked for cleanliness.
