Op dit moment mijn mooiste schermboemige. Laatbloeiend, daardoor een goede aanvulling op andere schermbloemen. Voor de bloei decoratief door het zeer fijne, frisgroene blad en rode stelen. Wordt ook niet lelijk na de bloei. Hoogte ca. 8o cm.

Selenium is designed to be used for web-based applications. Thus, Selenium is not used for mobile application testing. Selenium is however a powerful tool for web applications irrespective of the browser or the system’s operating system. This is why Selenium is popular. Want to learn more about automation testing?

It was a while since I spent an afternoon at the Parc de la Tête d’Or, Lyon, France, for a relaxing moment, dreaming in the tropical green houses, having a tasty waffle and doing candid photographies. I was then motivated for this but also for the quiet place to test in peace my new Zeiiss Ikon Contax iIIa (1952-1953, see the details about this iconic camera and the lens below). After a complete inventory and blank mechanical/optical checking, my venerable, almost 75-year old Contax was loaded with a black-and-white film FOMAPAN 100. The splendid Zeiss-Opton Sonnar lens 2/50mm was equipped with a 40.5mm protective Hoya UV filter and a generic Genaro shade hood. The light was metered using a Minolta Autometer III fitted with a 10° viewfinder for selective metering privileging this shadow areas or the hemispheric opale dome for incident metering. The weather was mild (22-23°C) but quite overcasted.

After the last view #38 exposed, the film was rewound to the taking cartridge and revealed in a Posso tank with 350 mL of Adox Adonal developer (identical to the original Agfa Rodinal in its formula of 1891) prepared at the dilution 1+50. The film was processed for 9min at 20°C.
The frames were then digitized using a Sony A7 camera (ILCE-7, 24MP) adapted to a macro Minolta Auto Bellow III with Minolta Bellow MD Macro lens 1:3.5 f=50mm and the dedicated slide duplicator Minolta. The light source was a LED panel (approx. 4x5') CineStill Cine-lite.
The RAW files obtained were inverted within the latest version of Adobe Lightroom Classic (version 15.5.1, July 2026) and edited to the final jpeg pictures without intermediate file. They are presented either as print files with frame or the full size JPEG's together with some documentary smartphone color pictures.
As a result, my Contax iia provided, crisp photograms, regularly spaced indicating a correct film transportation. At 1/1250s however, the upper side of the negative is under-exposed, likely due to slight unpairing of the curtains. The range-finder is correctly calibrated horizontally and to be recalibrated vertically.
About my Contax IIa (model 563/24):
I acquired this specimen at the annual photo fair of Saint-Bonnet -de-Mure, near Lyon, France on September 12, 2026, from a French specialist of vintage and collectible camera’s. Introduced in 1950 (Photokina) and produced in Stuttgart until about 1961 (approximately 66,000 units according to some sources), the Contax IIa is a thorough redesign of the Contax II while retaining the Contax mount (compatibility with most pre- and post-war lenses, except the pre-war Biogon 35 mm f/2.8 because of a narrower lens throat).
The main improvements and features are as follows:
- Smaller and lighter body (about 520 g versus ~610 g for the II).
- Vertically travelling metal shutter blades made of aluminium (lighter than the pre-war brass); the problematic silk ribbons were replaced by more reliable nylon cords/straps.
- Simplified and more reliable mechanism (smoother film advance and shutter cocking).
- Flash synchronisation added (initially via an intermediate cable on the back, later a standard PC socket from 1954).
- Slightly shorter but still wide-base rangefinder; combined viewfinder/rangefinder with a single eyepiece.
- Frame counter integrated into the advance lever; more convenient rewind knob.
- Two main versions: “Black Dial” (all shutter speeds marked in black, special sync cable) and “Color Dial” (from ~1954: 1/50 in yellow, higher speeds in red, standard PC socket).
The Contax IIIa (1951/1952) is the version with an uncoupled selenium light meter. Production ended around 1960–1961 in the face of the rise of SLRs (Contarex, Contaflex, etc.) and competition (notably the Leica M3 of 1954). Zeiss Ikon ceased all camera production in 1972.
The Contax IIa remained renowned for its build quality, reliability (when properly serviced), and optical performance, even though the shutter is still complex to repair.
About the lens Zeiss-Opton Sonnar 2/50 mm (standard lens):
The Sonnar 50 mm f/2 is the universal standard lens for the Contax, originally designed by Ludwig Bertele from his Ernostar. The classic formula (6 elements in 3 groups) minimises air-to-glass surfaces, a major advantage before anti-reflective coatings became widespread.
After the war, lens production split:
- In the East (Jena): Carl Zeiss Jena (often aluminium mounts, later chrome).
- In the West (Oberkochen): Opton / Zeiss-Opton was founded (1946–1947) to rebuild optical capacity. Lenses first carried the « Zeiss-Opton » name (with a red “T” indicating anti-reflective coating) until about 1953. After trademark disputes, West German Zeiss regained the right to use “Carl Zeiss”.
The Zeiss-Opton Sonnar 1:2 f=50 mm T (inner Contax mount) is the post-war version for the IIa/IIIa:
- New optical design (Bertele recalculated several Sonnar formulas between 1949 and 1951 using newer glasses).
- Anti-reflective coating (T).
- Chrome-over-brass rigid mount (non-collapsible).
- Typically 11-blade diaphragm; 40.5 mm filters.
- Production from 1950–1951; roughly 10,000 units for the early Zeiss-Opton series according to some estimates. Later variants appeared (black filter ring, diaphragm to f/22, then Carl Zeiss marking).
It offered excellent sharpness, the characteristic Sonnar bokeh, and comfortable speed for the period. It was the most common standard lens supplied with the Contax IIa (catalogue references 563/24 N or 10.1802).
Brief Contax chronology:
- 1932–1943: Contax I/II/III + Carl Zeiss Jena Sonnar in Dresden/Jena.
- 1945–1948: Destruction, Soviet occupation, transfer to Kiev, reconstruction in Stuttgart and Oberkochen.
- 1950: Launch of Contax IIa + Zeiss-Opton lenses (Sonnar 50/2 and 50/1.5, Tessar, etc.).
- 1953–1954: Switch to Carl Zeiss marking; Color Dial version of the IIa.
- 1961: End of Contax IIa/IIIa production.
The Contax IIa + Sonnar 2/50 mm represents the culmination of the Zeiss Ikon rangefinder tradition in West Germany: a robust, precise, and optically excellent camera born from the ashes of the war that shone until the SLR era.
Selenium toners increase the range of visible tones/shades without increasing relative contrast...interesting. I just like the color!
