Tamron 28-300mm F4-7.1 Di III VC VXD

The Tamron 28-300mm F4-7.1 Di III VC VXD is a travel superzoom for Sony E full-frame cameras. Its 28–300mm range spans everyday scenes and distant subjects in one lens. That reach suits travellers photographing wildlife, outdoor sport or distant landmarks.

Tamron released this lens in 2024, and it remains in production. The main trade-off is the variable maximum aperture of f/4 to f/7.1. The lens is brightest at 28mm and least bright at 300mm.

One lens means fewer changes and less to carry while travelling. Daylight rather than dim interiors is therefore its natural setting.

At 1 lb 5.5 oz (610 g), this lens is light enough to carry all day while travelling. The body runs 4.96 in (126 mm) long and 3.03 in (77 mm) wide.

A 67mm screw-in filter attaches directly to the front thread, so a polariser or protective filter needs no adapter.

The 28mm end frames streets, interiors and group scenes without stepping back. Zooming toward 300mm makes distant subjects larger, which suits perched birds, outdoor sport and compressed landscape views. The middle of the range covers portrait-friendly focal lengths. This spread makes it useful for a mixed day of city walking and wildlife watching.

The specification score for optics is 56 of 100. The maximum aperture starts at f/4 and narrows to f/7.1 at 300mm. In daylight this matters little, and the deep depth of field helps keep whole subjects sharp. In weak light, the small aperture instead pushes ISO settings up. Background blur also stays modest, because depth of field remains deep even at 300mm.

Close focus reaches 0.6 ft (19 cm). The maximum magnification of 0.36x also lets a flower or small object fill the frame. Depth of field becomes very shallow at close distances, so focus placement takes care.

Built-in stabilisation steadies the camera at slower shutter speeds, which helps most at the 300mm end where hand shake shows. That helps for static subjects in early morning or evening light. It does not stop subject motion, so a running animal still needs a fast shutter speed.

Weather sealing protects the lens against rain and dust during outdoor use. The fluorine coating helps water and oil slide off the front element, so cleaning after a dusty day is easier. A zoom lock keeps the barrel from extending while the lens hangs from a strap, which can happen at the long end. The features score is 78 of 100.

Inside, 20 elements arranged in 13 groups include three aspherical elements. Their shaped surfaces help correct distortion, where straight edges such as building lines appear curved.

Two low-dispersion elements help reduce chromatic aberration, where colours focus differently and leave fringes along high-contrast edges. Fringing of that kind often shows at long focal lengths. Internal focusing moves glass inside the barrel, so the lens does not grow longer as it focuses.
