Eagle’s Eye tessar type Citograph 50
– the Citograph story continues

CP Goerz introduced the first Citograph lens – the Citograph 35, a one of its kind hyperfocal fixed focus lens successfully in 2017 through kickstarter and has just started to ship the lenses.

With this project we take Citography to the next level. Unlike the Citograph 35 its bigger brother – the Citograph 50 – offers the complete aperture range from f 2.8 to f 16 But it is a true Citograph again: ultra compact, ultra light, easy to use and it creates super sharp images. Like the 35 it is a professional grade lens based on the famous tessar type construction.

A lens type that was called “The Eagle’s Eye” for a good reason has been redisgned into a pancake size lens with great contrast, sharpness and extraordinary color richness.

Citograph 50
– the perfect tessar type lens for 21st century photography


The lens creates an exceptional image quality due to its outstanding focal point sharpness. The razor sharpness make this lens a high performance lens for the modern camera and their sensors. Full format or APS-C.


Looking at the bokeh characteristics of the Citograph 50 the charm of this lens becomes very clear. But of course we all know that Bokeh is very subjective and therefore very difficult to parameterize in a objective manner. So it is best that you see for yourself what you can do with this wonderful lens.


The Citograph 50 lense offers great color accuracy and intense expression of the colorful life around you. This can become a breathtaking feature when we you go out into nature or if you are into animal photography.

Eagle Eye
– a legendary lens design returns to Citography

The Tessar type lens is probably the most outstanding lens design ever. It is relatively straightforward and consists of four elements in three groups, one positive crown glass element at the front, one negative flint glass element at the center and a negative plano-concave flint glass element cemented with a positive convex crown glass element at the rear. It was designed by the famous Dr. Paul Rudolph while he was working at Zeiss, Jena, and patented by Zeiss in the year 1902.

The advanced Carl Zeiss Jena Tessar 50mm 2.8 is often referred to as “Adlerauge” (Eagle’s eye) due to its’ image quality and sharpness. Its elegant simplicity makes it the perfect design base for the Citograph 50. We have designed a tessar type lens with its typical sharpness, bokeh and contrast in a pancake lens of finest quality. With an estimated 150 million Tessar type lenses build in the 20th century this lens design is most likely the most successful one of all times.

But it was not only quantity that is outstanding. Quality of the images with great sharpness without being clinical or sterile was the big virtue of this lens. This is why at around 1925 people paid the same price for 100g of gold than they would pay for this lens. In today’s world this would mean over 4,000 US $ for this lens.

The C.P. Goerz Citograph 50 is true tessar type pancake lens. The visual language of the Citograph 50 is as unique as a fingerprint. Natural sharpness and soft, versatile bokeh characterize this lens. Only 23 mm of heigth (DSLR)/ 32 mm (Mirrorless) make this lens a tool to be tucked away in the photographers pocket to be ready in an instant.

Join the Vision

At C.P. Goerz we wanted to continue the Citograph philosophy with a full grade but easy to use lens in a unique ultra-compact and light design. We guarantee superior quality of the components with a butter soft yet precise turn of the focusing ring.
A dream like soft bokeh supported by 12 steel aperture blades complete this resurrection of the eagle’s eye lens. The clickless aperture ring supports the photographer in his quest for the perfect shot – still or videography. The Citograph 50 supports spontaneity and real life photography. Its aperture ring is divided not only into the well know individual f stops but also into zones of different artistic characteristics. Photography is spontaneous and you can capture that magic moment instantly! You get a lens with specially coated glasses but with all the perfect Tessar type characteristics and flawless mechanical construction.

A Legend Perfected
– Tech Specs of the Citograph 50

The lens has been designed to be very compact and it looks tiny compared to modern lenses. It is a “Pancake” style lens with small dimensions but gigantic performance. The lens is very solid and serious. The focus ring rotates very smooth and perfectly damped.
From closest focusing distance to infinity it makes a 270° turn, which makes focusing very precise. The front element doesn’t rotate while focusing. The aperture ring has no stops and no clicks. Also distortion of the lens is very low and not visible. A big plus of the lens are the colors it recreates.

They are saturated, contrast rich and well-balanced. Its minimum focusing distance is only 35cm, so that it is also a nice lens to use for close up shots. The bokeh is unique and has a very slight, unobtrusive softness to it, which can be very appealing for portraiture. The lens has 12 aperture blades and creates a very special variable background rendering.


C.P. Goerz – our mission, our quality

We want to establish a kind of photography that focuses on the image not on technology. No gimmicks, just pure manual photography but easy to use, unobtrusive in its design with gretat quality and image results – that is what we want to create.

So Citography is a completely new form of spontaneous and pure photography, allowing you to create beautiful and highly professional photos of the world around you – create images that are just as unpredictable and spontaneous as life around you. Perfect quality, easy photography but affordable prices for outstanding meachnical and optical quality – that is Citography as well.

With the CITOGRAPH 50mm and of course as well in combination with the Citograph 35mm, you can truly express yourself and tell your very own story – from your own unique viewpoint, without compromising on image quality. They offer a creative freedom that has so far not been possible in photography.
