Tamron 150-500mm F/5-6.7 Di III VC VXD A057

This Tamron 150–500mm zoom suits distant subjects such as birds, wild mammals and outdoor sport. You can tighten the view on one animal or zoom out to include more of its surroundings. It also suits airshows in suitable conditions.

Separate versions fit Sony E, Fujifilm X and Nikon Z cameras. The Sony E version arrived in 2021, Fujifilm X in 2022 and Nikon Z in 2023. Sony E and Nikon Z support full-frame bodies; Fujifilm X cameras use APS-C sensors, which give a narrower view from the same position.

The main trade-offs are weight and a maximum aperture that narrows as you zoom. Bright conditions make it easier to keep a fast shutter speed for action.

The Fujifilm X version weighs 3 lb 12.3 oz (1710 g) without its tripod mount and measures 8.26 in (209.9 mm) long. Its body is 3.66 in (93 mm) across. Other mounts differ. Support helps during long sessions. Screw-in filters must match the 82mm front thread.

At 150mm, you can include a larger animal or some of its habitat. Zooming toward 500mm tightens the view from the same position. This helps when your location is fixed.

Maximum aperture runs from f/5 at 150mm to f/6.7 at 500mm. As the aperture narrows, shutter speed becomes the working constraint. A bird in flight in soft light may need a higher ISO to keep the shutter fast enough. In strong daylight the aperture is easier to live with.

Closest focus is 2 ft (60 cm) at 150mm, measured from the sensor. At that setting, maximum magnification is 0.32x. At 500mm, the minimum distance is longer and magnification falls to 0.27x. A nearby bird can become too close to focus when you zoom in.

Long settings can soften a distant background behind a nearby animal. The separation depends on the distances involved, even at f/6.7. Branches directly behind a bird can remain distracting. Moving to a different viewpoint, when possible, can give the subject a clearer backdrop.

The built-in VC stabilization counters the camera shake that long focal lengths magnify. It steadies framing in your hands, so handheld work at 500mm becomes more practical. It does not freeze a running animal, so motion blur remains a shutter-speed decision.

Moisture-resistant construction helps outdoors. Use cover in persistent rain. A fluorine coating helps water and oily marks wipe away from the front glass. Remove loose grit before wiping it.

The FLEX ZOOM LOCK can hold any zoom position. Slide the zoom ring to engage or release it. This helps prevent the barrel moving under its own weight while carrying or using the lens.

The shared design uses 25 elements in 16 groups. Five LD elements and one XLD element help reduce chromatic aberration, which can leave coloured fringes along high-contrast edges. A bird against bright sky is one place those fringes can show.

Two hybrid aspherical elements help correct distortion and spherical aberration, which can bend lines or soften detail. The Fujifilm X version uses internal focusing, so focusing does not extend its barrel.
