And here it is advertised in the late 60s. Looks sketchy, but these were fine lenses made by Kenko. They also were sold under Kenko and Soligor branding, probably more.

The lens used is a 180 degree .15x fish eye lens made by Spiratone.

In recent years, buying new filters i’ve mostly stuck to Tamron, Fujifilm, B+W (citylight) and Hoya.

You'd think that adding an adapter and a teleconverter to a vintage M42 ("universal thread mount", as found on #Pentax, #Yashica, #Fujica etc) would make for a combo that is too heavy and too long for normal use. It really depends on the lens you combine it with.

Here it is combined with a #Spiratone #reflex #Mirror #Lens, 300mm f5.6. The whole thing is smaller than my #Fujifilm 50-230, and about the same weight but almost twice the reach.
