The Tamron 70-300mm f/4.5-6.3 Di III RXD is a remarkably compact and lightweight telephoto zoom for full-frame Sony mirrorless cameras. Covering portraits, travel, outdoor sports and wildlife, it provides useful 300mm reach without the bulk traditionally associated with full-frame telephoto lenses.

📷 Versatile Telephoto Coverage

The 70-300mm range is useful for a broad variety of subjects.

At 70mm, it works well for full-length portraits, nearby action and larger subjects. The middle of the range handles candid photography and outdoor events, while 300mm provides useful reach for wildlife, field sports, aircraft and distant details.

🦅 Substantial 300mm Reach

The 300mm telephoto setting allows photographers to isolate distant subjects and simplify distracting backgrounds.

When used on a compatible Sony APS-C camera or in APS-C crop mode, the lens provides a field of view similar to approximately 105-450mm on full frame.

⚡ Fast and Quiet RXD Autofocus

Tamron’s Rapid eXtra-silent stepping Drive provides smooth, accurate and quiet autofocus for still photography and video.

The lens supports compatible Sony features including Eye AF, Fast Hybrid AF and continuous subject tracking. Its quiet operation is particularly useful for wildlife, ceremonies and video recording.

🔍 Excellent Optical Performance

The 15-element, 10-group optical design incorporates a low-dispersion element to help control chromatic aberration and color fringing.

Tamron’s BBAR coating suppresses flare and ghosting while maintaining strong contrast and natural color around bright light sources.

🎒 Exceptionally Lightweight

At approximately 545g, the lens is one of the lightest full-frame 70-300mm mirrorless zooms available. Its manageable size makes it easy to carry while traveling, hiking or attending outdoor events.

The lens accepts compact 67mm filters, matching many other Tamron mirrorless lenses.

🌼 Useful Close-Focusing Capability

The lens focuses as close as approximately:

• 80cm at 70mm

• 1.5 meters at 300mm

At its longest setting, it provides a maximum magnification ratio of approximately 1:5.1, making it useful for flowers, larger insects and other smaller subjects that cannot easily be approached.

🎥 Suitable for Outdoor Video

Quiet RXD autofocus makes the lens useful for recording wildlife, sports, performances and distant subjects.

The lens does not include optical Vibration Compensation, so it benefits from a Sony camera with in-body stabilization, a tripod or a monopod—especially when recording near 300mm.

🛡️ Designed for Outdoor Photography

Moisture-resistant construction provides added confidence when working outdoors. The front element features a fluorine coating that repels moisture and oil while making fingerprints and dirt easier to remove.

Its lightweight construction is particularly beneficial during extended handheld sessions.

• Outdoor sports

• Travel and sightseeing

⚖️ How Does It Compare?

Compared with the Tamron 50-300mm VC VXD

The 50-300mm begins wider, includes Vibration Compensation, offers faster VXD autofocus and provides much stronger close-up performance. The 70-300mm is lighter and provides a simpler, more affordable telephoto solution.

Compared with the Tamron 50-400mm VC VXD

The 50-400mm begins wider, reaches farther and includes stabilization. The 70-300mm is substantially smaller and lighter, making it easier to carry while traveling.

Compared with a 70-200mm f/2.8 Zoom

A 70-200mm f/2.8 provides better low-light performance and stronger background separation. The Tamron reaches another 100mm while remaining significantly lighter and more compact.

Compared with a Standard Kit Telephoto

The Tamron is designed to cover a full-frame sensor while remaining lightweight. It provides excellent reach and can also be used on Sony APS-C cameras for an even tighter field of view.
