Olympus offers two different lens hoods for 50mm lenses, the #108233 for

and 35-70mm f3.5-4.5. All of the above lenses employ 49mm filters. Why
does Olympus sell two different hoods? A suitable hood for 35mm f2.8
would probably also be good for 50mm f1.2. A suitable hood for 50mm f1.2
is definitely good for "lesser" lenses like a 50mm f1.8. You see my
point? If this were a mathematics list, we'd have a nice discussion of
overlapping domains. I wonder if the separate hoods aren't a holdover
from the days of when the prime 50mm lens used a 55mm filter, and when
the lens changed to 49mm filter size, someone forgot to eliminate the
redundant hood.

Since my 50mm 1.4 rubber lens hood clamps around the outside of the barrel
the filter diameter does not matter.

True . . . in practical use either hood will work on any of the 50mm
standard lenses. IIRC, there's also a very early screw-on metal hood.
The 50mm hoods are clamp-on without a lip and can be reversed over their
respective lenses for storage. The barrel of the 50/1.2 has a larger
diameter, thus the 50/1.4[1.8] hood cannot be reversed over the 50/1.2
lens. Dark brown leather case noses were also made for various 50mm
lenses, the most common of which is the "1,4" for a 50/1.4 but occasionally
a "1,2" case nose is found for the 50/1.2 lens. Its snout is a slightly
larger diameter and may be slightly longer (I have one). The lens plus
reversed hood will fit into it.
Among the dark brown leather cases, the number stamped on the bottom part
of the nose that wraps under the body indicates the lens: e.g., "1,4N",
"1,2N", "1,4H". The "N" noses are semi-hard, have straight tapered sides
and fit tighter. The "H" noses are hard, have curved flared sides and fit
looser around the sides. The early light brown hard cases and black
pebble-grain semi-hard cases I've seen for OM-1[n]/2[n] bodies don't have
these markings but will fit at least a 50/1.4 with reversed hood (the ones
I have don't fit the OM-2S/OM-3[ti]/OM-4[T] bodies with integral hot
shoes). All these cases for the single-digit OM's are leather and quite
durable. I've seen some dark brown leatherette single-digit OM cases
constructed like their leather counterparts and they are just as
non-durable as the ubiquitious black OM-10 cases.
The collectors will likely scurry around trying to find all the variants of
cases and noses now. ;-)
