Tamron's budget full-frame telephoto zoom — 70-300mm with macro mode, no stabilisation.
The Tamron AF 70-300mm f/4-5.6 Di LD Macro launched around 2008 as one of the cheapest telephoto zoom options for full-frame DSLRs. It provides basic telephoto reach with a macro mode at 180-300mm offering 1:2 half-life-size magnification.
Optical quality is basic — acceptable centre sharpness at mid-focal lengths but soft at 300mm and at the edges. LD (Low Dispersion) glass helps reduce chromatic aberration. No image stabilisation makes handheld use at 300mm challenging. AF is adequate but not fast.
Available in Nikon F, Canon EF, and Sony A mounts. 62mm filter thread. Approximately 435g — lightweight. No weather sealing. Full-frame coverage. The macro mode between 180-300mm provides useful close-up capability at approximately 95cm minimum focus distance.
Very cheap used — often under £30. The lack of stabilisation is the main drawback. The Tamron SP 70-300mm VC USD is dramatically better. The Canon 55-250mm IS STM and Nikon 70-300mm VR are superior first-party options. Only for absolute budget telephoto needs.
