We are in the process of building a back-end database with data for all Pentax lenses. In this process we're reviewing the information we already have collected.
Many sources including
ourselves here claim two versions:
#1: Super-Takumar Fish-Eye 1:4/17
#2: Super-Multi-Coated FISH-EYE-TAKUMAR 1:4/17
This is in line with Pentax lens manuals from way back when.
We have photos of #2.
However, I have never seen a photo of #1!
Instead I have seen photos of a
Fish-Eye-Takumar 1:4/17
The photos reveal that this Fish-Eye-Takumar 1:4/17 has auto aperture and therefore would have been entitled to the "Super" in its name.
My preliminary conclusion is that Pentax marketed this lens under the name Super-Takumar while the engraved name was Fish-Eye-Takumar (no "Super").
Do y'all agree or is a third variant of this lens in existence?
