Tamron 25-200mm f/2.8-5.6 Di III VXD G2 (Model A075)

The Tamron 25-200mm f/2.8-5.6 Di III VXD G2 (Model A075) is a superzoom for Sony E full-frame cameras. It arrived in 2025 and remains in production. The span runs from a slightly wide 25mm to a long 200mm, so one lens can cover a whole trip. Use the short end for streets and interiors, and the long end for distant subjects.

The main trade-off is speed. The aperture opens to f/2.8 at 25mm but falls to f/5.6 at 200mm. Handheld shooting in dim light at the long end therefore needs some planning. Travel and everyday photographers who want one lens for everything will get the most from it.

The Tamron weighs 1 lb 4.3 oz (575 g) and measures 4.78 in (121.5 mm) long. Screw-in filters fit the 67mm thread on the front. One filter covers the whole zoom, so a polariser for skies at 25mm also works at 200mm.

The 25–200mm range is the reason to buy this lens. At 25mm it frames interiors and street corners with a little width. At 200mm it makes distant subjects larger: a bird across a field, a performer on a far stage, a facade detail high on a building. Between those ends, the zoom handles portraits and general views.

The variable aperture sets the main limit. At f/2.8, the wide end keeps ISO low indoors and in evening streets. As you zoom toward 200mm, the maximum closes to f/5.6. Daylight telephoto shots stay easy, but at dusk you will raise ISO or slow the shutter.

Nine aperture blades keep the opening close to round when stopped down. This helps out-of-focus areas stay smooth in portraits at the wide end.

Close focusing adds a useful bonus for a travel zoom. The lens focuses as near as 0.5 ft (16 cm). Its maximum magnification reaches 0.53x, which fills the frame with a flower, a market find, or a plate of food.

Weather sealing guards the joints against dust and moisture, useful on beaches, dusty trails, and wet markets. A fluorine coating on the front element sheds water and oil. Spray and fingerprints wipe off with a cloth instead of stubborn smears.

A zoom lock stops the barrel from creeping open in a bag or on a sling. The zoom itself is electric and rotary, so a motor drives the focal length.

There is no stabilization built into the lens. Steady handheld results at 200mm therefore depend on your shutter speed and on any stabilization in the camera body. Features specification score: 52/100.

The optical formula uses 18 elements in 14 groups. Two of them are aspherical, specially shaped surfaces that help correct distortion and spherical aberration. That correction matters when you photograph buildings at the wide end.

Four low-dispersion elements help reduce chromatic aberration, the coloured fringes that can appear along high-contrast edges such as branches against bright sky at 200mm.
