Sony A7 IV
The Sony A7 IV (2021) is a Full frame (35 mm) camera with a 33-megapixel sensor (7008×4672 px) and a 1× crop factor. Its 36×24 mm sensor and 5.14 µm pixels shape its depth of field, its field of view at each focal length, and how large you can print.

With its 1× crop factor, a 35 mm lens on the A7 IV frames roughly like a 35 mm lens on full frame. The examples below are computed from the A7 IV's exact sensor size and 33 MP resolution, so they match your camera rather than a generic sensor.
Depth of field examples: Hyperfocal distance @ 24 mm f/8 = 2.42 m · Max shutter (500 rule) @ 24 mm = 21 s
