Here is a review of a pair of C.P.Goerz D.F.99 German Army prismatic binoculars. C.P.Goerz (Carl Paul Goerz 1854 - 1923) started life selling Mathematical instruments to schools.

By around 1887 his interest turned to selling cameras, this was followed a year later by the take-over of the workshops of F.A. Hintze's, creating the company Optische Anstalt C.P. With this company, Goerz produced cameras and lenses. By 1890, Goerz had moved production to Berlin-Friedenau. Goerz was not content with just selling one product, and quickly the company was producing a whole range of various optical instruments.

Seeing the potential for Ministry orders, he started to develope a range of binoculars in the late 1890's, and in doing so, he was competing against his major rival of Zeiss. In the year 1899, Goerz produced a prismatic binocular, which he offered to the German Ministry for testing. This proved successful, for early in the year 1900 an order was placed by the German Ministry and full scale production was started of the model known as '1899'.

Zeiss was already using a well established D.F. Code system for their Ministry binoculars, so Goerz kept the system and stamped the binocular 'D.F.99' The D.F., stood for 'Doppelfernrohr' (Double-Telescope), and this can be traced back to binoculars that Zeiss were producing in the year 1874. In the year 1903, more orders were placed, and Goerz opened a department at the Berlin factory solely for the production of military optics. The new model was known as the D.F.

The Goerz business rapidly grew, and they quickly became the worlds biggest producer of military optics. It was also around this time that they started to produce a series of refracting telescopes. The year 1903, also saw the company floated on the Stock Market.

Never one to miss out on advertising, Goerz proudly proclaimed that his company had produced around 130,000 binoculars by the year 1907. This got under the skin of his rivals Zeiss, who made a counter-claim a year later. It was clear that Goerz was rapidly becoming a thorn in the side of Zeiss. The company also went on to open branches in several countries around the world, including the UK. Interestingly, Goerz supplied the British War Ministry with optical instruments, and had previously worked with the British company Barr & Stroud, becoming their sole representative in Germany in the year 1898. As part of this agreement, the British company was allowed to send a representative to the Friedenau works, and James French thus worked at the Berlin factory for a year, studying all aspects of optical production.

Renee undeleter torrent. Goerz was now a highly successful company, and with the out-break of World War 1, yet more business was placed by the both the German and Austrian War Departments. The company was producing binoculars with a 30mm objective version appearing to have been the standard instrument for officers during the War, lower ranks had to make do with Galilean binoculars. Rifle scopes, U-Boat periscopes and searchlights were also produced for the Government. With the end of WW 1, things quickly started to go bad for Goerz, for the company appears to have struggled in the post war chaos of Germany. The situation was compounded even further by the Peace Treaty of Versailles which prevented Germany producing military equipment. In 1926, the German branch of Goerz was merged with Contessa-Nettel, ICA and Ernemann to form a new company known as Zeiss-Ikon by the year 1927.

Zeiss was the controlling share-holder of the new company and declared that lens production would only be carried out by Zeiss, thus the coffin-lid was finely screwed down on their old adversary of Goerz. During its time, Goerz had produced thousands of optical instruments for both military and civilian use.

REVIEW OF GOERZ D.F.99 PRISMATIC BINOCULAR Unfortunately I can't find one single image of the binocular that I have The nearest I can find is in this link: and: The body shape is the same as mine, but the D.F.99 does not have any focusing wheels between the two binocular bodies and the two bridges are different. The binocular has a distinctive angular shape, with the body appearing to have been made from cast aluminium. Inside are various ledges for the prisms to sit on. The condition inside the body is very clean indeed, and it was sobering to think that the last time someone inspected the prisms was probably when the instrument was made some 110 years ago. The covering is brown leather and was not stitched, but instead Goerz chose to glue the leather to the body.

At each end of the bodies are heavy brass bridges, running along the inside of each body are heavy brass plates that connect the body to the bridges. At the eyepiece end is a small set-screw on the bridge, when the correct eyepiece distance is obtained, this screw is tightened up.

The binocular also has what looks like the original leather neck-strap. On the left-hand prism housing plate is stamped 'C.P.Goerz Berlin', underneath this is 'D.R.P'. On the opposite plate is 'D.F. 99', and underneath this is 'P. When Goerz made this model, it was offered to officers of the Prussian Army at a special discounted price of 95 German Marks. In return the paying officer could assign a unique serial number to the binocular, thus the P. Stood for 'Private Number'.

The number on my model is a very low 3 digit number. Wether this number is a serial production run number is not known, if it is, then the binocular I have must have been one the first to be made. It also raises the possibility that the number is a personal Army number relating directly to a Prussian officer? If so it might just be possible to trace the original officer who purchased the binocular if this is the case. It is known that these binoculars were used by Artillery officers.

I have also found a picture in an old book of a German Officer with a pair of these binoculars. Goerz also supplied yellow filters, distance measuring reticle and compass at extra cost. The lenses are tiny, at only 20mm diameter, and the magnification is x7.

Each eyepiece is focused individually by turning a knurled metal ring around the base of the eyepiece stem. Instead of rotating, the eyepiece moves up or down.

There is a marked scale running all the way around the eyepiece stem. All metal parts are painted black and are made from brass and aluminium or alloy.

When using, the angled sides of the body slip very nicely into the hand making them nicer to hold than my pair of modern Zeiss 8x30. In spite of the tiny lenses and un-coated prisms, the view is quite bright in daylight and the optics are very sharp indeed. The eyepieces have good eye-relief, and observing with them is very relaxed. Goerz described his binoculars as being good in low light situations in the early morning or late evening.

He was also one of the very first to promote his binoculars as being good for astronomy and in particular the study of variable stars. It has been estimated that the un-coated surfaces in the Goerz have a light-loss of around 37%. In my skies I was struggling to pick out stars fainter than magnitude 7.0. But I did manage to see M13 as a very small fuzzy ball. I estimated the field of view at around 6°. Goerz D.F.99 PROS Very nice to handle, sloping body sides fit the shape of the hand extremely well. Nice comfortable viewing images.

Extremely sharp optics, as good as any modern day binocular. One of the very first mass produced prismatic binocular. A nice history piece.

CONS Small objectives and un-coated prisms, providing limited use for astronomy. As they only cost me £11, I'm not complaining, for I now own a piece of interesting history for my collection. If any one can add more information for Goerz then please post, for I may be lending the binoculars for display at a local Museum. So any information would be helpful. Thanks for reading. As an up-date to the review of the D.F.99, I completely stripped them down and cleaned all the prisms and lenses. The standard of engineering and machining within the prism body is truly remarkable.

Over the last week, I've been using them extensively and have found them to be an excellent binocular. Also after using them in better sky conditions, I've revised my opinion of the limiting magnitude reached by the small 20mm lenses. According to Goerz advertising from April 1899, the limiting magnitude for their Trieder binoculars was mag.7.5 and 8.0 for the x3 and x6 models, while the x9 and x12 models would reach magnitude 8.5 and 9.0 on a clear moonless night. The x3 and x6, had 15mm lenses, while the x9 and x12 both employed objectives of 20mm. As the D.F.99 is x7, I would think that they would be somewhere in between the x6 and x9 models. It has been predicted that with the 37% light-loss, the x9 models would reach magnitude 7.8, rather than mag.8.5 as stated in the Goerz advertising. During the week, I had a good night (for me) with a naked eye limit of around mag.5.0 - 5.0.

While observing R UMa, I managed to see a comparison star of mag.8.2 and then glimpsed a fainter star, which turned out to be R UMa. I estimated the magnitude of R at around mag.8.3/8.4. Several other variable stars were checked out, and in all cases I could not detect stars of magnitude 8.5, but 8.3/8.4 was observable. It seems to me. That even with the light-loss, the information given in the Goerz literature is correct in the figures that it quotes. Goerz also mentioned how much better their prism binoculars were for astronomy, when compared against Galilean binoculars.

Going head to head against my Dollond's, I have to say that I think the Dollond Galilean's is a better instrument for astronomy, and I cannot see any real benefits that the prism binocular had over the Galilean optics that could be purchased at the time.

I really hate to do this but two guns came up for sale that I've been search YEARS for and I need to free up the money to buy them before someone else does! I was originally going to build a K98 Sniper rifle clone using this scope and I can't believe I'm going to do this.

Goerz 'Tricertar' Pre-WWII Variable Scope! History of the Goerz Company: C. Goerz was founded in 1886 by Carl Paul Goerz.

Originally, it made geometrical drawing instruments for schools. From 1888 it made cameras and lenses. During the First World War, Goerz's main production was for the German and Austrian military.

During the mid to late 1920s Zeiss bought the controlling share of Goerz and eventually forced them to stop producing their lenses due to the quality being as good if not better than Zeiss! The Scope: This scope is estimated to be made in the early 1920s and is rumored at being the first variable scope that was produced for the civilian market. Zeiss currently makes the claim that they were the first, which is partly true since they purchased the Goerz company. This scope seems to be insanely rare! I've only found references to 4 or 5 other Tricertar scopes on the internet! The scope was rumored to be a vet bring back taken off a K98.

I have no idea if that's true but the date is there. As you can see the scope was made in Berlin and has a serial number to the scope. I cannot find any info on if there was that many Tricertar scopes made or if the serial number was for all Goerz made products together. Now to the cool part, it's variable! The lowest setting is 3-1/3: Then 4-1/2: Finally 5-2/3: Like all old scopes it only has an elevation adjustment, windage was done by whatever mount you were using. But what about the glass?

Well it is AMAZINGLY clear! No picture will do the lenses justice!

So what do I want for it? Well I really don't know what it's worth. Due to the rarity and amazing quality of the optics, around $1000 or best offer Located in Williams Lake, BC Canada.
