Hi - jm - What gives you that idea? Go back to earlier threads, where Ron Mowrey discussed this, relative to his own days at Kodak. Ektar 25 was the earlier prototype, with some of the same blue-cyan repro issues, but considerably worse. I did try it. But I admittedly can't speak about whatever performance distinction there might have been in the intermediate 125 version, and never in fact ever saw a roll of it for sale here. Except for curiosity testing purposes, neither of them would have been of any value to me anyway, because during those years I exclusively shot large format sheet film. Another transient mini dinosaur I've never seen for sale was Ektar 1000.
