Frequently asked questions
What does LD mean?
LD stands for Low Dispersion glass, which reduces colour fringing.
Does the Tamron SP 300mm f/2.8 LD IF have stabilization?
No. Stabilization has to come from the camera body if it has sensor-shift stabilization; otherwise use a faster shutter speed or a tripod.
How close can it focus?
Minimum focus is 3 m. At this focal length that keeps you well back from the subject.
