As I commented some weeks ago, I have a blog entry dedicated to Rollei
filters and I have received some questions about them. There is some
confusion about Rollei H1, Rollei UV, Rollei R1, Rollei R2 and Rollei
R1,5 filters function:

Rollei UV: This is a filter for B&W photography only, it does not work
fine for color photography because it has a color tint, this filter
has a strong effect to block UV rays, it’s very goodfor high mountain,
snow, water surfaces,  high and distant landscapes.

Rollei H1: It could be used for B&W photography however it was made
from 1950 for color photography mainly. Rollei literature says this is
an UV filter and Skylight filter for landscapes with haze, to
eliminate the blue cast coming from the atmosphere, the UV filtering
is soft and perhaps it wouldn’t work fine at the high mountain. Rollei
also says this is a filter for Xenar and Tessar lenses; Planar,
Xenotar and Sonnar needn’t it, thanks to the “glass” used to make
these lenses ( some Rollei brochures say it), anyway Rollei
manufactured the filter for BII and BIII too but for fewer years than
for BI. Firsts color films were very sensitve for the blue and UV
light.

Rollei R1: This color conversion filter has an UV filter  effect and
slight color warming effect for Tessar and Xenar lenses, it does not
have UV filter effect for Xenotar, Planar and Sonnar but it has slight
color warming effect for these lenses.

Rollei R2: It’s a bit stronger than R1 and has UV filter effect and
soft warming effect for every Rollei TLR lens.

Rollei R 1,5: This filter was manufactered from 1957, after R1, R2, R5
and R11 color conversions filters were no longer manufactured (1966),
it would be equivalent regarding a Skylight 81 A or B filter, Rollei
manufactured this filter up to a few years ago and perhaps it’s still
manufactured.

It’s interesting to read about UV and Skylight filters tests, there
are a lot of differences for the filter effect according the
manufacturer, coating, glass, design, despite the glasses look so
similar.
