The new Kodachrome was first marketed in 1935 in the 16mm home movie format, and in 1936 in 8mm as well as in 35mm and 828 roll-film sizes for amateur still photography. Later it also became available as 120 roll film and 4x5 sheet film for professional use. Initially it had a &quot;speed&quot; equivalent of ISO 8 in today&#x27;s terms, but later versions had &quot;speeds&quot; of 25, 40, 64, and 200.
