Attic found: brass Darlot lens and Schneider filter

[mattdang]

Hi
I have found some lenses and really don't know much about them.
One is with the engraving Darlot Opticien Paris (it is huge and heavy).
The other one is a portrait lens, possibly by Darlot, since it was made in France.
And a B+W Schneider filter with a brass filter claim/holder ring (what mounting is this?).

I don't know anything about large format camera lenses, so if you know anything about those lenses and filter, please tell me.

Thank you so much!

The "huge and heavy" short lens looks like a wide angle Aplanat or similar.

The portrait lens can be either a Petzval portrait lens or a Portrait Aplanat; if you can estimate the max aperture that that should tell which it is.

The Schneider filter has a fitting for an Aero-Xenar, or perhaps even a Schneider Göttingen Aerotar. What's the filter diameter? That looks like it might conceivably fit my Aerotar!

Sigh.....

That clinches it, the next place I move into needs to have an attic......

It's always fun to discover. The fatter lens is a Darlot Wide Angle Hemisperical, I'm pretty sure. They usually have 3 lever stops, but perhaps you have an earlier or larger one that doesn't. Note, the very early (you'll have to research the serial number) ones were actually a partial hemisperical design, like the Harrison Globe. Later they changed them to rectilinear types, but kept the hemi name for sales reasons.

Thank you for your information goamules, I have researched the serial number, it is 4xxx. According to the posts by Milan Zahorcak, the big lens seems to be the earliest lens have ever found to have the name Darlot alone.

Wide angle darlots can be fantastic lenses.

I haven't seen the aero-xenar. Can anyone confirm fitting for this brass (copper?) fitting?

[Ole Tjugen]

The Aero-Xenar is shown in the 1934 Schneider catalogue at http://www.cameraeccentric.com/html/...hneider_3.html

As far as I have been able to find out the Schneider Göttingen Aerotar was a WWII product only, but only by interpolating ISCO serial numbers. They have no records of ever having made one - nor any other records for much of WWII...

Hi Ole Tjugen,
Thanks for your information. I've found the information on the filter. It is for the Schneider Gottingen Xenon lens on military airplane camera during WWII. You are awesome.
