I just bought this lens (because it's an Asahiflex lens and it also comes with the desirable original Asahi M37 to M42 adapter, which I recognized because of the vertical slit in te adapter). I like the two-tone design of the lens (almost like a small 125mm f/2.5 Apo-Lanthar), but any ideas as to who could be the maker? My Google searches end in a black hole; Simor seems to be very obscure. Not that many Asahiflexes were sold, so finding 3rd party lenses for them is uncommon indeed.

I think it's fair to assume that this lens was made in the late 50's (it would make no sense selling lenses for the Asahiflex in the early 60's). maybe the "A" serial number points to a certain maker?

Addendum: I noticed this eBay auction with a 35mm Simor lens with a Fujita "FT" serial number:

Very interesting ! Nice find !

It could very well be a Fujita as its known that some lenses were made by them in Asahiflex mount.
The style is similar to several makers of the time.

Short list of suspects -

Fujita
Kyoei
Taisei (Tamron) - there are apparently several lenses made by this firm prior to the adoption of the
Tamron trademark, that are completely undocumented.

My copy of a Soligor labeled lens looks identical to the above Simor. There are a couple listed in Ebay at the moment with the Soligor label. I am not going to speculate who the maker is, but its built different than other Soligors I have in the 135mm range.

Besides the name difference on the name-ring I noticed a difference in the "mm" after the focal length. The copy I own has dots after each "m".

Mine came with an Exakta mount.





It works very well too Very Happy

The other possibility is Komura.I'm guessing this one also has 15 blades.
So it's a 14 blade. Confused

Is that the original case? If so, Sankor supplied the same cases with their lenses.

I'm not sure if it's the original case; it's completely unmarket. And of course, many lens makers back then had the same suppliers. Especially for generic items such as lens cases.

Any new clues? I will post a few simple photos in the oversized gallery.
