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. Its aperture is fixed at f/6.3, so shoot in aperture priority (A or Av), where the camera sets the shutter speed, or in manual exposure. 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.

Sony: the camera sees no lens attached, so turn on “Release w/o Lens” in its menu, or it will not take a picture. Sony's manual
Fujifilm: the camera sees no lens attached, so turn on “SHOOT WITHOUT LENS” in its menu, or it will not take a picture. Fujifilm's manual

What it frames

From 20 m back it takes in a scene about 1.6 × 1 m on the a6400. A mirror lens: mirrors inside fold the light, so this 300 mm lens is only about 74 mm long, and out-of-focus highlights show as rings (Samyang calls it “donut-shape bokeh”). It focuses down to 90 cm from the sensor.
