With its adjustable focus the (most important) recommendation in Polaroid's literature is applicable.
Higher resolutions will resolve the RGB color screen which can impact image quality.
This is a high quality imaging device.

Note both cubic and linear scaling were used to create the smaller images displayed on this page. Any scaling will exaggerate imperfections.

The heavy moire lines of the street scene is likely due to a combination of the film base RGB filter lines and chromatic abberation.
