Magic Lantern was originally written for the Canon EOS 5D Mark II[3] by Trammell Hudson in 2009 after he reverse engineered its firmware.[1] He ported it to the Canon EOS 550D in July 2010. There are now versions for many other Canon DSLRs and the current principal developer is known as A1ex.
Since installing Magic Lantern does not replace the stock Canon firmware or modify the ROM but rather runs alongside it,[3] it is both easy to remove and carries little risk.[4] The camera checks a "boot flag" in its re-writable memory, and if set, reads from a memory card to get the additional firmware routines. Each time the camera is started, there is an option to disable Magic Lantern.

Magic Lantern firmware was originally written for the Canon EOS 5D Mark II[3][2][5] by Trammell Hudson in 2009 after he reverse engineered its firmware.[1] He ported it to the Canon EOS 550D[6] in July 2010.
Starting in September 2010, a person using the name "A1ex" on the CHDK (Canon Hack Development Kit) website forum and other people ported Magic Lantern to the Canon EOS 50D,[2] 60D,[2][7] 500D[2] and 600D.[2][7] As of August 2017 support for the Canon EOS 5D, 5D Mk III,[2][8] 6D,[2] 7D,[2][6] 60Da, 650D,[2] 700D,[2] and 1100D[2] DSLRs and the mirror-less EOS M[2] had also been added. Later mirrorless cameras are not supported because they use a codebase similar to Canon PowerShot cameras rather than Canon EOS cameras; therefore CHDK ports are planned.[citation needed]
Originally developed for DSLR filmmaking, Magic Lantern's features have expanded to also include those for still photography.[4][9]

Because installing Magic Lantern does not replace the stock Canon firmware or modify the ROM but rather runs alongside it, it is both easy to remove and carries little risk.[4] Canon has not made any official statements regarding the add-on firmware, either on the subject of warranty or on the features.[13][unreliable source?][14][unreliable source?] In response to emails Canon has stated that while their warranty doesn't cover damage caused by third party firmware, it will cover unrelated issues such as malfunctioning buttons even if third party firmware has been installed.[15]
