Tamron Di III 18-300mm f/3.5-6.3 Di III-A VC VXD
The 16.6x zoom range covering a 27-450mm full-frame equivalent field of view and a 1:2 maximum magnification at just 5.9 inches eliminates the need to swap lenses. Its VXD linear motor delivers fast, quiet autofocus, complemented by effective Vibration Compensation and weather-sealed construction in a compact 620g body. This lens is best for travel and landscape photographers using Sony E-mount APS-C cameras who prioritize framing flexibility over a wide aperture.
