I'd love to find some that had been frozen. I liked Agfa too and in particular their three saturation levels that allowed choices we don't have today. Ektar is vivid and saturated but not like Ultima 50 was - it was sort of a negative Velvia, maybe even more saturated. When colors needed to pop, it would pop them. Portrait 160 had those green Caucasian flesh tones and muted almost pastel rendering that is great for portraiture and also for giving some scenes a dreamy quality, and Optima 100 was just a really good overall film. I do still have some frozen Optima 100 4x5 (not sure how much I have left) and a few rolls of 220 (!) that I got in a bulk purchase, in my freezer.
