If I want the best possible results in terms of grain and resolution there is, in my opinion, one choice...Konica Impresa 50. This film is not well distributed and can be hard to get. It is of moderate to low contrast and offers exceptional discrimation of various hues. This film is everything that Royal Gold 25 should have been. I use it with my 35mm on a very stable tripod...Majestic 2501..with the mirror locked up and hoprfully with an aperture of F5.6 or wider open with a good quality prime lens. This is as good as it gets as far as I am concerned.
