I have a Pen FT half-frame 35mm camera. Because the film area is so small, fine grain is important to me. I've been using Ektar 100 but it's just to slow to be versatile in a camera that goes 72 shots between film changes. I figured the new Portra 400 is probably the finest grain 400 speed color negative film, but it's not available at freestyle yet. Has anyone compared the new Portra 400 with the old 400VC/NC films? Did you find that it was significantly less grainy or about the same?
