Dont't give up yet! The reason there is no OM-adapter available is probably
that there is no room for a lens release button. The other camera brands
have the button on the housings, so there is no problem.
I've got a Zenitar 16/2.8, originally in Pen*ax K-mount. I took the mount
off and replaced it with one from a discarded Zuiko 50/1.8 (yes, it was
already dead, so I thought of it like an organ transplant...). It required
a little sanding to get the mount thickness right, but it was definetely
worth the time spent. The diaphragm was automatic, but a spring from a pen
make it permanently stopped down. This leaves two problems, or rather "issues":
1. There still is no room for a lens release button. The lens still fits my
cameras and stays in place, so I don't care.
2. Spot metering have to be done at full opening to get correct values, and
f/2.8 in bright sunlight will frequently give shutter speeds over 1/2000
with all but the slowest films. Spot metering with a 16mm fisheye is a joke
anyway, so I usually use a normal or short tele lens for metering and
transfer the settings to another camera with the fisheye mounted.
Back to the lens in question: the first picture clearly shows the M42
mount, and it has three screws clamping the mount to a flange inside. You
can use a common T2-adapter for OM, loosen the 3 or 4 screws around the
inner ring, and substitute the outer part for the M42 mount. In other
words, the Peleng sells with what can best be described as "half a T2 mount
for M42", and it can probably be replaced. I've done this with a russian
MTO 1100mm f/10.5, and the mounting shown looks exactly the same. This way
you also get a lens release button!
