The F2T was a special ultra-rugged version of the F2 (DE-1 head) with titanium bayonet mount, top and bottom plates, and camera back, plus a special DE-1T titanium covered meterless prism head, sold in parallel with the regular F2s from 1978 to 1980. Most F2Ts were given a special textured black finish but a very few came in natural titanium finish, including the first F2Ts and the very last F2s ever manufactured. Their serial numbers began with '92', e.g., "F2 9201544.'
