Lentic: slow moving water, including pools, ponds, and lakes.

LENTIC (The new project by Ember Swift) (2009)

There were previous lenticular cameras aimed at amateurs, such as the 6 lens Lentic, introduced in 1953, which used 120 roll film, but the Nimslo was probably the first to use 35mm film, and certainly the first that could fit in a pocket.
