What it frames
From 3 m back it takes in a scene about 3.7 m wide at 18 mm and 1.5 m wide at 45 mm on the EOS R50.
With autofocus, Canon gives a closest focus for each zoom setting. At 45 mm it focuses down to 35 cm from the sensor, where a subject about 14 cm wide fills the frame of the EOS R50 (0.16x); at 18 mm, down to 20 cm, about 16 cm wide (0.14x). Focusing by hand gets closer: at 45 mm, 25 cm from the sensor, a subject about 8.6 cm wide (0.26x).

Where it is picked first
Each camera page picks one lens per job by a stated rule, from the numbers alone; the kit guides build on those picks.
Everyday and travel: first pick on the EOS R100, EOS R50, EOS R50 V, EOS R10 and EOS R7
The rule: a zoom from about 28 mm to at least 70 mm equivalent, lightest first.
