Before the first shot
Turn the focus ring until the subject looks sharp; focus peaking (sharp edges outlined in colour) and the magnified view in the viewfinder or on the screen make that easier. The camera cannot set the aperture, so shoot in aperture priority (A or Av) or manual exposure: the camera measures the light through the lens at the aperture you set on its ring. Check the first pictures and correct the exposure if they come out too dark or too light: Sony's guide warns that the camera may not measure the light correctly through a lens without electrical contacts.
- Canon: the camera sees no lens attached, so turn on “Release shutter w/o lens” in its menu, or it will not take a picture. Canon's manual
What it frames
From 3 m back it takes in a scene about 4.8 × 3.2 m on the EOS R50. At its closest (28 cm from the sensor) a subject about 28 cm wide fills the frame of the EOS R50.
