What it frames
From 3 m back it takes in a scene about 4.1 m wide at 17 mm and 1.4 m wide at 50 mm on the a6400.
Tamron gives a closest focus for each zoom setting. At 50 mm it focuses down to 30 cm from the sensor, where a subject about 9 cm wide fills the frame of the a6400 (0.26x); at 17 mm, down to 19 cm, about 11 cm wide (0.22x).
