I remember there was a long thread on one of the rec.photo groups some five
years ago on this topic. Then, however, the observations went the other way
round; Pentax was claimed to be the winner of colour rendition.
As others have said there are many other factors that can affect colour
rendition. I'll add my share:
Hardangervidda is a mountain plateau some 1000m ASL. There's more UV light
up there (personal experience), and the snow doesn't make that any better.
Maybe there is a difference between makes in the UV transparency of the
multicoating?
There are differences between films in UV sensitivity too. Are you sure you
took the same motifs with the same films?
You shot with an MX. I have been to Hardangervidda (and other mountain areas
in Norway) with both a P50, MX, LX and Z-1 under similar conditions of snow
and bright lights. My experience is that the MX light meter handle this
situation poorly. It tends to underexpose scenes with snow, and it also
seems to have the most temperature- and humidity-sensitive meter of the
four. Note that both the P50 and the LX also have centre-weight meters, but
with other technology than the MX.
