Hi Dirk:
I found my old Rollei catalog, it says:
"H1 (Not necessary for use with the 5-element Planar, Xenotar and Sonnar) UV
filter, especially designed for long distance colour photography...."
It was quite neutral'cause it was recommended for regular color shooting
(landscapes especially), not for high mountain, lakes, rivers, beach and snow
that require stronger UV filters.
