I'm not surprised but it's disappointing. I haven't shot color slide film in years in a still camera but I do shoot Ektachrome 100D in Super 8mm and would love to be able to continue shooting it and projecting it. I checked Kodak's web site to see if there was any information about Ektachrome 100D in Super 8mm and couldn't find any. I filled out their online form to request information about 100D Super 8mm availability and will post again if I hear any news.
I'm never quite sure where Fuji stands on product availability. Do they still make sheet E-6 film? It would be a shame if there were no options left for transparency sheet film users.
