Dallmeyer 8" f2.9 Pentac would fit the bill.
One of many obscure Schneider lenses from the 1920s that show up a few times and then disappear without trace. There are so few of them that based on the last digits alone I think this might be...
By the time the Symmar-S was released the Copal 2 was already defunct, so the 240 moved up to a number 3 shutter. I really only know the Schneider lenses, but I assume maybe the 180 Tessar was in a...
Yes, although I'm not sure whether it is working correctly. The camera came without lenses but had Copal 2 size mounts installed. I've cobbled together a pair of 180 Xenars for display, but the...
My two TLRs: on the left is (I think) the earliest type without parallax correction while on the right it has manual correction via a scale and a set screw.

I have a couple of Gowland TLRs, both different designs (probably earlier) to the one in Tin Can's photo. The bigger one with twin 360 Tele-Xenars weighs in at 4.6kg (10lb 2oz) while the other with...
The information is from a series of books by Hartmut Thiele called "Grosses Fabrikationbuch Schneider-Kreuznach" which is basically a printed spreadsheet with all of the lenses produced between March...
Your lens is recorded in the production lists as a prototype ("muster"), one of a batch of three produced on 28 January 1969. Interestingly there is also a batch of three prototype 355/9 S-Clarons...
The only size 0 shutters I have seen are ones with external control boxes. I have a Prontor Magnetic in size 0 which has a cable attached with a connector on the end and a couple of Compur Electronic...
FWIW, the batch sizes in this period were usually 5% over a round number i.e. 105 instead of 100 or 210 instead of 200, so at a guess this was the expected maximum reject rate.
After looking again I should revise things slightly; the earliest examples of Technika labelled lenses I could find in the Schneider production lists date to 15 April 1955. That was a set of 5...
The Linhof specific branding on Schneider lenses, i.e. Technika-Angulon or Technika-Symmar didn't start until mid 1956, so there is no reason why these couldn't have been cells supplied by Schneider...
While they are very useful books to quickly investigate a lens via its serial number, trying to get any sort of overview of production is quite tedious and prone to error as your eyes glaze over...
The first prototype Plasmats were a batch of 5 of the 135/5.6 in February 1952, followed by the 150 in May 1952 and then the others in December 1952.
The last of the Dagors was a batch of 50 of the...
There is a series of books that give the precise production dates for this era. Your lens was completed on 24 March 1955 which makes it a really early example. In this period the normal focal length...
Thanks for that. It was from a batch of 600 lenses, so definitely not a prototype. Regardless of the barrel that it came in, we can probably regard the four element construction as typical for the...
Arri, what's the serial number for your lens? I'm just wondering where it fits in the chronology.
I've checked the production lists (Hartmut Thiele's "Grosses Fabrikationbusch Schneider-Kreuznach Band II") and there are multiple batches for both a 150/9 and 150/11 G-Claron produced in the 1970/71...
I think your biggest challenge is going to be working out how to detach and reattach the rear of the bellows when you convert from Press camera mode to SLR mode and back again. Everything else has...
Hello! Probably more of us Melbourne LF people around than you would think.
Paul.
Kind of been here before, but that was not what Linhof did. There was no pool of lenses to pick from, Schneider manufactured to order and delivered a batch of lenses. As per Bob's explanation in a...
There shouldn't be any noticeable difference, they are built to the same specifications.
If your existing mount has the aperture scale marked on it all you need to do is measure the aperture diameter and transfer it to the new shutter. You don't need to derive the f/stop from first...
You could buy them new in a Compur Electronic 3, but that didn't change the maximum aperture. f5.6 is the maximum aperture for that design regardless of how it is mounted and a number 1 shutter is...
The Komura 33mm f4.5 fish-eye for 4x5 definitely exists in the catalog, maybe not in the outside world.
To slightly rephrase what Mark has said about correction, the manufacturer could choose to correct for best results with the indvidual cells or best results with both cells together. As I understand...
To confuse things slightly more; when the Compur 2 and Compound III, IV and V became unavailable Schneider responded by using the next shutter size up with adapter rings/bushes to make up the...
Big thing to remember is that Australian size carry-on luggage (for domestic travel) is smaller than US size. It is very rare for it to be weighed on Qantas or Virgin, but an oversize bag is pretty...
At a guess, it means it was available in either a Compound III/7 or a Copal 3. See the one directly below it the lists a V/12 + 5FS, that would be a Compound V or a Compur-Electronic 5S.
(edit) I...
That era of Tele-Xenar would have been in a Compound III/7, which is the same as the 300/5.6 Symmar. Overall length is given as 110mm or 111mm in a few different brochures from the 50s and 60s. The...
There is a reprint of the repair manual for sale on eBay at the moment. I won't link to it, but a search on "Compur Electronic" should find it for you.
It is a Vario-Claron (242-258mm), so some sort of industrial lens. A photocopier lens is a good guess.
The Gowland SLR is a much simpler beast than a Graflex and would be something that a reasonably skilled person could hope to replicate. The drawback is that has a single speed shutter, meant for use...
No, nothing but the bare bones of focal length and maximum aperture. Occasionally you will find out the shutter size/type for production lenses but the lists are basically when/what/how many/serial...
One of three prototypes ("Muster") assembled on 4/4/61 - along with 77.5 f4, 150/4.5, 180/4.5 and 300/4.5 versions as well for good measure.
The triple convertible Schneider Symmars had the longer focal length at the front as did the Angulons.
It is a set of three books by Hartmut Thiele called Grosses Fabrikationsbuch Schneider-Kreuznach Band I, II and III. From what I can tell it was self published in Munich in 2006 and is written in...
March 4, 1968. One of a batch of 50 that was completed that day.
I bought a reproduction repair manual from here: http://www.photobooksonline.com/books/shuttersrepair.html (#8183). It is basically a single speed (1/125) mechanical shutter that has an electronic...
Coincidentally, I recently purchased a set of Schneider Symmar cells that were made for the Graflex 1000 shutter. They are one of three sets of prototypes made in 1962 and are marked as 180/6 (not...
