Kodak T-Max 400
Kodak describes it as a continuous-tone panchromatic film with high speed (ISO 400/27), very high sharpness, very fine grain and very high resolving power (F-4043). Tabular T-Grain emulsion.
Sheet film listed as 4x5 (Wikipedia list); wider sheet sizes for some Kodak films come via a Canham Cameras group-buy scheme. Eastman Kodak sells it as Ektapan 400 in the US and Canada from March 2026 (Wikipedia list); Kodak's pages do not say so.
