Hello, guys
Today on the market I found this beauty for 85 $.
On the lens: Aplanat Rectilineare Rapide; Hess & Sattler; Bayreuth
No diaphragmMaybe somebody have scans of diaphragm which I could use as templates for making new one?
or have more info about this lens?
I'll try to do some testing tomorrow
There appears to be a slot for Waterhouse stops- which can be made from cardboard for openers, then metal as you confirm the fit, etc
Sold by Hess & Sattler who must have had a photographic store in the non-industrial town of Beyrouth - then experiencing a tourist boom because of the establishment of Richard Wagner's memorial theatre! It might be a F6 RR/aplanat rather than the usual F8.
Wow great storyOriginally Posted by Steven Tribe
I'll check in the morning if it F6 or F8.
What are analogical lens to this Aplanat from other manufactures?
Looks like an f:8 to me...
A great number of German manufacturers made Aplanats,but this one has enough French writing on it that I suspect it of originating in France. Something reminds me of Derogy, but I have no idea what.
The sharpest lens I have ever used, without exception, is a Meyer Aristoplanat. That was Meyer's name for the Aplanat...
Focus to infinity 21 lens diameter 3,6. When 21/3,6 = F 5,83 (so F 6)
Correct me if I'm wrong
From your picture, the diameter of the front cell (glass only) looks to be about 2.8cm, but the ferrule might be confusing me.
21/2.8 = 7.5...
And is the focal length measured to the rear flange, or the stop slot?
The rule in the picture isn't exactly in the middle of lens.
I measured from the rear flange.
I think the variation in engraving styles says a lot about this obejctive. The only engraving that looks like the makers engraving is the APLANAT. The shop name in capitals has all the signs of a seller's non routine attempts with poor spacing. The free hand engraving of both the french "rapide..." and the "Beyreuth" look like they were done by the same hand. So, I would guess this is a German optic were the seller has tried give the objective an international "flavour" for his opera loving clientele. It worked - this was perhaps sold to an American Wagner fan visting the Opera House?
Right - so add a half lens body length to the flange focal distance, and you end up with something like 240-250mm focal length. A 30mm entrance pupil would fit a 240mm f:8...
I see no real difference between the style of the "Aplanat" and the rest of th e engraving. Different fonts yes, but this was made at a time and place where the frontispice of a book could easily have twenty different fonts on the same page.
Hand engravings are not uncommon on lenses of that vintage, either - quite a few of mine are partly hand engraved, including lenses from Rodenstock, Meyer, Voigtländer, Steinheil, and others...
