I'm new to film so to speak in the realm of 4x5, I have used film in my 35mm camera but not the low ISO 50. Why is it that many of you like this film. I know that it is a slower film but what can it do that the 100 wouldn't do, is it the grain factor, or what? I'm wanting to try some out to see but would like some thought from you folks first. I'd like to know what type of shooting you mostly do with it. Is the new better than the older film?
