I need guidance on a mirrorless camera, to be set-up on the ceiling of large plans.

The plans cannot be hanged vertically on a wall for a technical reason. They have to be flat on a table not even inclined. So camera has to be ontop of the table taking pics from a Birdseye view.

Plans are around. 130cm x 90cm large.

Lense has to be light as with gravity focus would be effected.

Quality has to be good to be able to read even faint notes in pencil on the old papers.

Which camera and lense would you recommend and why? I am thinking that camera should be setup approximately 1.5 meters from the surface of the table.
