What it frames
From 3 m back it takes in a scene about 5.9 m wide at 12 mm and 3.5 m wide at 20 mm on the a6400.
Tamron gives a closest focus for each zoom setting. At 20 mm it focuses down to 28 cm from the sensor, where a subject about 21 cm wide fills the frame of the a6400 (0.11x); at 12 mm, down to 18 cm, about 14 cm wide (0.17x).
