Tamron 14-150mm f/3.5-5.8 Di III Review – Focusing
With a stepper motor employed to drive the focus group, the Tamron autofocuses silently and accurately. The slow maximum aperture at the telephoto end means it will often be rather slow when focusing in low light, but in daylight it’s pretty snappy. Manual focusing works well, and the camera’s focusing aids engage automatically when the focus ring is turned. With a minimum focus distance of 50cm, the lens is capable of impressive close-ups.
