[4] Kamera lens lives as a saprobiont[3] and can be found in hay infusions.

[5] The first valid description (as Monas lens) was published by Otto Friedrich Müller in 1773.

[3] David J. Patterson and Michael Zölffel found Woodcock's description to be insufficient and established the genus Kamera for Kamera lens in 1991, creating a play on words in the binomial's resemblance to "camera lens".

[4] Due to lacking ultrastructural or molecular biological data, the species' rank is uncertain; thus it is placed as incertae sedis in the Eukaryota.

The taxonomy of this group is currently under revision so the position of the genus Kamera should not be regarded as being settled at the moment.
