I've never quite gotten around to trying Tech Pan, although I'm going to have to very soon. Pan F+ is almost like an all-purpose film compared to Agfapan 25. Easier to control and more forgiving - - like a fine grain Tri-X -- you can still get nice prints out of less-than-perfect negs. I use it in XTOL 1:1, and I find its EI to be something more like 32. Pan F+ has an extended blue sensitivity, which means blown out skies unless you use a filter (yellow-orange-red). I like it a lot.(posted 8944 days ago)
