Tamron 28-200mm f/2.8-5.6 Di III RXD - Sony E Mount

The Tamron 28-200mm f/2.8-5.6 Di III RXD is an all-in-one superzoom for full-frame Sony E-mount mirrorless cameras. It is notable for starting at f/2.8 at the wide end, a rarity for this lens class. The lens is relatively compact and lightweight, making it suitable for travel and general-purpose photography where carrying multiple lenses is impractical. It features a Rapid eXtra-silent stepping Drive (RXD) motor for quiet autofocus and moisture-resistant construction. When purchasing this model used, inspect the zoom ring for smooth operation across the entire range and check for excessive zoom creep. SDS technicians verify the autofocus motor is responsive and silent, as well as checking the rear mount and front element for scratches. Ensure the weather-sealing gasket at the mount is intact and that there is no significant internal dust that could impact image quality at narrow apertures.
