Tamron's basic non-stabilised 70-300mm — the LD version without VC or USD motor.
The Tamron AF 70-300mm f/4-5.6 LD is the most basic version of Tamron's long-running 70-300mm telephoto zoom, featuring LD (Low Dispersion) glass but lacking VC stabilisation and USD motor. Available across virtually every DSLR mount, it provides 300mm reach at the absolute minimum cost with the benefit of improved chromatic correction from the LD elements.
Optical performance is basic. The LD elements provide better chromatic aberration control than completely uncoated alternatives. Centre sharpness is acceptable at shorter focal lengths but weakens at 300mm. No stabilisation is the main practical limitation. Autofocus depends on the body's AF system — typically adequate but not fast.
Available in Canon EF, Nikon F, Sony A, and Pentax K mounts. Filter thread is 62mm. Weight is approximately 435 grams — lightweight. Build quality is basic plastic. Multiple versions exist — the Macro designation on some versions allows closer focusing. The VC USD version is significantly better at a modest price increase.
Extremely cheap on the used market — often under £30. Check for smooth zoom and AF. The LD elements are the only distinguishing feature over completely basic alternatives. Not recommended when the VC USD version is available at modest additional cost. Adequate only for bright daylight casual telephoto work.
