I once had a large Meopta enlarger for 5x7", and it came with a Belar 210mm. Magnitarus was the name of the enlarger, or something like that. Never user the lens in a camera, so I cannot speak about...

In my copy, 2nd edition, the only bullets I see are in a table in page 116. One bullet (dot) represents 1/3 stop increment while two bullets represent 2/3 stop increment between zones.
It is this...

In a pinch you could try a Russian I-37 300mm f/4.5. AFAIK those are made following the Tessar formula and are easy to get and inexpensive.

There is a guy in Prague, Czech Republic, who builds and sells LF cameras. He doesn't have a website that I know of, but is on FB:

Thanks, Steve. I just sent you a PM with my email address.

Hello,

I have a Ilex n.5 shutter that is missing a spring in the slow speed train. The shutter is the Ilex variant made for Kodak and it came with a Ektar 12" lens.
The slow speed train was...

But Mark, Julia M. Cameron never actually focused, why'd she need a loupe ;-)

Be it as it may, and whatever history it had, your loupe is very cool. Keep it ...

Bill, I wouldn't go as far as saying that this lens belonged to the royal family. More probably it belonged to a UK government agency at some time, and they marked their ware to avoid it being stolen...

Surprisingly similar to a Queen Victoria monogram (VR for "Victoria Regina") as can be seen here:

Sorry, I just saw this. If you still need measurements let me know. I have a 240mm Heliar f4.5 in a Compound 4 (model 10 as per Ole Tjugen chart)

The guy actually sells three, possibly unrelated, objects: a Red Dot Dagor, a box from a Schneider lens, and an old Schneider label. The label is originally from a Tele-Xenar, and somebody wrote...

carel,
the Hermagis n.16944 shown in Corrado's book is a Petzval, so yours, which is very similar, is almost certainly a Petzval too.
Anyway the Hermagis, at least the ones which I had in my hands,...

I found the thread that I remembered about Apo-Lanthars, it's from 2005:
http://www.largeformatphotography.info/forum/showthread.php?15047-Voigtlaender-Apo-Lanthar

Stefan, that is a nice lens you...

Except that the later APO-Lanthars maybe ended up having no Lanthanum at all. Lanthanum is mildly radiactive and some people would see it risky to walk with one of these lenses in their pocket. I...

I have only two Hermagis from the period. One of them, n.17631 only has the usual engraving with the name on one side, nothing on the other side. No number.
The other, n.38478 is engraved also on...

Pete,
There are indeed many variations of the technique.
As you have been told, there are papers that you can use without sizing. But once you size with gelatine, by all means harden the gelatine...

Alô Coisas. Thanks for the information. I had taken the screw out, but the ring refused to move so I was afraid to break something and left it at that. Now I see that I have to "convince" somehow the...

Mine is a Voigtländer Apo-Lanthar. Nice lens but the shutter is frozen. You can see my original post here;...

I made this same question here a few months back but didn't receive answers. So I'll be following this thread. I have a similar shutter but probably smaller. It's for a 150mm lens.

Yes, I know. I was just reacting to a previous Bob Salomon's post in this same thread.

"A wide angle is the length of the short side of the negative or shorter and a long lens is equal to the long side of the negative or longer"
Do I understand this correctly? Since the diagonal is...

Taulen, get in contact with FomaFoto (http://www.fomafoto.com/). They are somewhere in Norway and they distribute films and papers made by Foma Bohemia. They don't seem to distribute Foma x-ray...

Stefan,
Try the Czech FOMA. Their list of distributors is here: http://www.foma.eu/foma/dokumenty/RadioDistribuce.asp

I need some help from anybody that has opened one of these shutters. I believe that under the conical front piece is a standard Synchro-Compur. But I need to remove the front piece first. Any cue?
...

Sevo,

Thanks for the clarification. I had read somewhere that the DRP was still used in Germany.

Tom

DRP is an abbreviation of "Deutsches Reich Patent", which means something like "Patent of the German Realm". So yes, it's the patent number. DRPs started to be used in Germany around 1877. I think...

Cyrus,

I just measured a few of my old glass negs. The smaller ones (6x9cm) have thicknesses between 1.4mm and 1.7mm. A 13x18cm is 1.6mm and a 18x24cm the same. A larger one, a 10"x8" from 1908 is...

Ok, the confusion is mine, I missed the "Darlot" text completely, since it is in a shadow. Thanks for making me notice that. Anyway I must be the only one on this thread who doesn't actually own a...

I don't know the size of the lens, I got the pictures from a dealer in Paris, but he has since sold it. Not too large, in any case. It was also part of a casket, as you can see. What puzzles me is...

Just for reference, this is a similar specimen of Jamin (not mine, alas) with the front in its original state. I notice that on the back, behind the cone which in this lens is not very conical,...

Thanks to all that took the interest and the time to comment on my question.

After reading all your posts, I'm no less puzzled than before, except that there now seem to be more possibilities than...

I have a lens made by W. Brown in London. Up to now I have been unable to find any references to this maker (or reseller) in books, the VM or in the Net.

The lens is marked as a 10x8 Rapid...

I have a Ross Cabinet n.1 somewhat later than yours (s.n. 32117, between 1875 and 1880). Front and back elements are of similar diameter, and the lens is generally as described in the catalog page...

I notice that the magazine article mentions that this particular Euryscop is built using magnalium, an aleation of aluminium and magnesium. However your lens seems to be built with brass...or is it?...
