I have had an F5 for 10 years, and have used it extensively with slide film, in the mountains for winter photography. Here that means most of the year since snow in the Cdn Rockies starts in early Oct and lasts until June. I found that the F5 matrix meter is very reliable in these conditions and hardly ever 2nd guess it. For my style, I usually dial 0 compensation , sometimes + 1/3 EV compensation if snow dominates the scene and let the meter decide. It is rarely wrong.
I agree with Chan about negative film - I usually give + 1 EV with negative film.
