|
|
The Kodak serial numbers had an "L" to signify that it was coated.
127mm kodak has the "L"
135mm Graflex just has a serial number
152mm kodak has the "L"
203mm Graflex just has the serial number.
Is a Graflex lens just a rebagged kodak?
I have seen the 203mm kodak lens with the "L"
My Graflex lenses look as if they are coated. How can I tell?

Terminology and nomenclature.
Kodak named their top of the line lenses Ektars.
Wollensak named their top line lenses Optars (or Tele-optars)
Either of these lenses could be found in a Kodak Shutter called a Shuttermatic, a Wollensak shutter called a Rapax or a Graflex shutter called a GraPHex, which is a relabled Rapax
Do the lenses (around the glass) say Graflex on them?

135mm Graflex Optar f/4.7 No778002 in a Graphex (X) shutter (Is this coated?)
127mm Kodak Ektar f:4.7 RC3154L in a Graphic Supermatic (X) shutter (this is coated?)
8" (203mm) Graflex Optar f/7.5 NoG53055 in a Graphex shutter M M FX off (Is this coated?)
From what I have read the kodak 203mm was f7.7

I would think all of these are coated. The Ektar is from 1950 And the two Optars are in late shutters.
While there may be exceptions, I believe Wollensak changed the name of their tessar design from Velostigmat to Optar when the coated them. The lack of an L or a Circle W may be that these were the first generation coatings. There was a lot of talk about the new "Lumenized" ektars when they came out and it may be a different coating than the non labeled versions.
There is a 127 f4.7 lens for a Speed Grapic on Ebay right now in a Graphex shutter labeled Velostigmat. It's clearly not coated. (search under "graphic,old,sharp" to find it |

Surely Optar was Graflex's house name for the lenses they sold. Wollensak's name for
most of their post-WWII lenses was Raptar.
Wollensak lenses without a Circle W are uncoated. To add to the confusion,
late 135mm Optars were made by Rodenstock. |

the 135 could be a rebadged Wollensak or a
rebadged Rodenstock. The s/n doesn't look
like a Wollensak one, does the lens say
'lens made in Germany'? |
