What it frames
From 3 m back it takes in a scene about 0.2 × 0.1 m on the a6400, one person or a detail rather than a group.
At its closest (2.5 m from the sensor) a subject about 13 cm wide fills the frame of the a6400.
Sony lists its 1.4x and 2x teleconverters (SEL14TC, SEL20TC) for this lens. With the 1.4x it becomes 560 mm at f/6.3 and frames like 840 mm on the a6400; with the 2x, 800 mm at f/9, like 1,200 mm.
