The only very fine-grained film I've ever discovered that had long exp range (a long relative straight line
to the characteristic cuve, reminiscent of some faster films) was Efke 25 (now discontinued). It worked
wonderfully in ordinary developers including my preferred pyro options. By contrast, micro-films like
Tech Pan needed special developers, were always disappointing in the shadows and highlights, and had
poor edge effect, so actually looked less sharp in a typical print. Pan F works nice is your lighting isn't
especially harsh.
