I have also the Trousse Aplanastigmatique n.7 with 2x No7, plus one each of No 8 and 9 for foci from 12 cm (4.75in) combined to 40 cm. (16in.) single cell, usefull for 4x5.

Yes, I have one of those too...

Haven't tried it yet, since it arrived here after the light went south for the winter.


In all the incomplete Aplanatsatz'es I have, there are no two with the same threads. Bugger.

Ole send me some photos with a rough measurements of threads of your incomplete Aplanatsatz so I will check and I will see if I will be lucky.
If you need the same please let me know.

The only "special thing" I see with that one is that it's a 25 to 85cm instead of the more common 15 to 75cm.

Apart from that, I have absolutely no idea why it went over the top!

... Especially compared to this one...

Apparently a Carl Zeiss set as it is written on the box, but no markers name on the set it self.

it sais: "reticlinear eccelsior" on the barrel.

lenses: 15- 25 - 35 - 45 - 55 - 65 - 75

anyone knows about this?

And I have no idea how to mix the lenses....:rolleyes:

It looks very much like one of the Vade-Mecum'y Aplanat Satz sets, like the one I showed in (there was a url link here which no longer exists)

Some files on the way to you.

The site has been on hold for quite a while while I've concentrated on getting good at my new job. A few months before that I was about ready, then hit the problem with no longer having the email address I used to register it with, so I couldn't get access to approve moving it. When I checked just now that seems to have been resolved, so I'll continue with building the site as soon as I get my PC back from repairs.

Anyway, it's closer to launch than it's been in a long, long time!

In the meanwhile, my collection continues to grow slowly.

Here are some pictures of a Schulze & Billerbeck (often sold by and as Hugo Meyer) Euryplan Objektivsatz No. 2 für 9x12cm (borrowed from the seller):

Oh by the way: One of my incomplete sets is a "Meteor" too.

They seem to have been made in great numbers by Ridenstock, and sold under a number of different "seller names". They are to all purposes identical with the Vade Mecum, and give similar focal lengths.

One odd thing is that all the tables of focal lengths and apertures for combinations of these sets that I have seen so far are all identical, and all incorrect! The tables are made on the "basic formula" of 1/F = 1/F1 + 1/F2, without correction for the cell spacing. Same with the apertures - fno = F/d, without correction for the difference between physical aperture and entrance pupil. The differences aren't that great with the longer combinations, but with 15+25 the differnce is significant. Even the focal length is visibly different depending on whether or not you use the spacers.

So that's one project: Using a good optical bench (AKA Carbon Infinity), I should be able to measure the location of the nodal points and thus come up with a corrected table of focal lengths and apertures for generic Vade Mecum/Meteor/Satzaplanat sets.

At last, a preliminary version of the site is up.

It took a while to get the site moved to my "regular" web host, since I didn't have the email address I used for registering the domain. Then my computer crashed, and I lost what I had. Then I got a new computer, but...

And work. It always comes up at the wrong time! But now I've got my revenge - I've used an hour of work time to put together a preliminary site.

The next step is to do it properly, using something better for the job than MS Word.
And include pages for technical information, pictures shot with casket sets, formulas, old advertisements, get some detail pictures of some of them, get pictures of a Protar Satz, more information, a mail link/guestbook kind of thing, and...

Looked at the site, Ole. Seems like a very good start!

Now for a question: does the french word "trousse" imply that a lens is convertible?

Since "trousse" means "case" or "casket", I would think there's a very high probability of that.

I have received a few goodies today from England. It contained a casket set in a small leather purse along with a dallmeyer + an unmarked brass lens.

Can you help me identify these small gems ?

I all 3 types of lenses

Let's start with the "easy" one: The "unknown" is most likely a Rapid Rectilinear, and is probably British or French from the aperture steps. "22" and "44" is unlikely to be German, they would either use "22" and "45" or "23" and "45". Or Stolze. British manufacturers were more likely to use the infamous "AU" (Arbitrary Units", which is why I include France as a possible origin. Focal length is then likely to be around 9½" or 240mm.

The Dallmeyer? No idea really, especially not when I'm at work in the North Sea without a lens library. F:10 is similar to what many landscape lenses have, but this doesn't look like a landscape lens. Could it be a Periskop? Or an "unnamed Rectilinear"? I think the "UR" is most likely.

Then the casket set:

I assume that the "6", "14", and two times "20" comes from markings on the cells?

If so, I think that would have to be the focal length in inches: Most metric sets only go down to 150mm (or 15cm), since anything shorter than that won't be useable in combination with another cell. Since 150mm is about 6", it makes sense that it's a 6" cell.

a 14" front and a 6" rear would give about 4.2" combined focal length, quite within the useable range for an "uncorrected" wide angle Rectilinear. 14" rear and 20" front ends up at 8.2", again quite a useful focal length. And of course 2x20" is 10"; quite within the capabilities of most small cameras.

That 17mm thingy - does that consist of two short empty tubes? If so that's a spacer set, to be used in the "normal" configuration, and removed when extra wide coverage is needed. One goes on front of the barrel, the other one on the rear.

Given the markings in inches, a British maker is again most likely.

Ole & Emil

Yes it has a name - forgot to mention

Primus No. 1

// Ole - the 17mm thingy does contain of two tubes. most likely the inner is approx 7mm and the outer is 10mm

does this make sense

"Primus"... That looks like a Perken son & Rayment name. Could someone with the Vade Mecum look that up?

According the VM, Optimus is used as a name on many of the Perken son & Rayment lenses.
Primus does not come up doing a search on the VM.

jan

Correction, Primus was a trade name for Beck and the name Beck was not on the lenses sold as Primus.
A double Aplanat casket set is listed so it is possibly a Beck you have acuired.

Thanks. I must have been thinking of Optimus. Was Primus a Beck name - since you have VM available?

Darlot/Jamin casket



just got one...

But I don't know anything about it. The VM doesn't mention a lot (just "several"), and the one description is dated much later than this one must be, as the Jamin name is written on it.

Original case - "secret" compartment in the lid where the original flange and a front plate was hiding..

beautiful condition.
Compleate as I can tell.

on the lens is written "B" and "PORTRAIT" - on the base of the barrel it says "A".

I am almost sure the Portrait "mode" is a petzval...

6 extra lenses to combine - 8 waterhouse stops.

Anybody know about this kind of set?

Wow! That's the sweetest casket set I've ever seen bar none! Does the piece that says portrait effectively lengthen the barrel, ie. when it's in Portrait (petzval) mode, it has that piece to make the barrel longer, and when it's in regular mode with some of the aplanat components, the barrel is shorter?
