On September 7, 2024, at the annual photo fair of Saint-Bonnet-de-Mure, France, I found this Meyer-Optik Görlitz lens Oreston 1:1.8 f=50mm in M42 mount that I wanted to associate to my Praktica IV SLR camera body.
The lens was in acceptable condition for 20€ in the range range of price of my Praktica IV. Both were manufactured in Dresden, Germany in the year 1960’s. Oreston lens was marketed starting from 1965 in order to equip, in particular, the Praktica Nova that was anticipated to be produced massively by Pentacon for exportation (zeissikonveb.de/start/objektive/normalobjektive/oreston.html).
Oreston was a modern normal lens 6-lens double Gauss type, capable to compete with other foreign productions of that time, with a large aperture, automatic diaphragm mechanism, and optical performances that could not rival to Zeiss Jena productions (as the Flexon and Pancolar) but still very near at medium apertures.
For testing the lens, I loaded a 36-exposure black-and-white Fomapan 100.In the Praktica IV equipped with the Oreston lens. The lens was equipped a generic Yellow 49mm screw-on filter and a cylindrical modern shade hood for the views taken. The expositions were determined for 64 ISO instead of the nominal 100 ISO to compensate the filter light absorption, using an Autometer III Minolta light meter fitted with a 10° finder for selective measurements privileging the shadow areas or with the integrative dome for measurement of the incident light.

After complete exposure, the film was revealed using Adox Adonal (Agfa Rodinal) developper at dilution 1+50 at 20°C for 9 min. The film was then digitized using a Sony A7 body fitted to a Minolta Slide Duplicator installed on a Minolta Auto Bellows III with a lens Minolta Bellow Macro Rokkor 50mm f/3.5. The RAW files obtained were processed without intermediate files in LR and edited to the final jpeg pictures.
All views of the film are presented in the dedicated album either in the printed framed versions and unframed full-size jpeg plus some documentary smartphone color pictures.
About the Praktica IV camera :
I got the camera body Praktica IV and a set of related KDH Leipzig accessories from an eBay seller near Paris, France.. The whole arrived to me on January, 31, 2024, in Lyon, France.
The Praktica IV was designed by the prestigious KW (Kamera Werk Niedersedlitz) German company in Dresden on the basis of their previous Praktica FX SLR camera's. The camera was produced first under the KW name starting from June 1959 then within the Kombinat VEB Pentacon after the merge of the company in 1960.
166.800 Praktica IV and V (6 models) were produced until January 1966. Praktica IV essentially incorporates a condenser focusing screen plus a pentaprism. Due to the Praktica FX architecture the Pentaprism looks protruding from the camera body with an unusual style. It fits lenses with M42x1 mount and the mirror has no automatic return. The shutter is made of two horizontal curtains of rubberized fabric giving 1/500s to 1/2s plus B in two registers of slow speeds (1/2s to 1/10s) and high speeds (1/25s to 1/500s). The film is advanced coupled to the shutter cocking using either the right upper button or the rapid lever underneath the body.
The Praktica IV handles the "Auto" M42 lenses with the lever for automatic iris closing upon the release. Sequentially, when pressing the shutter release button, the diaphragm closes to the indicated value, the mirror is lift-off and finally the shutter is erased at the given value. If a non-auto (manual closing) M42 is used the pushing lever could be cancelled (declutched) moving a small red button to the right in the mirror chamber.
The camera camera came without lens but with a body cap and the original ever-ready leather bag with et "Ernermann tower" Pentacon logo. This model is likely the second Praktica IV essentially the same as the initial KW one with a different front plate. The camera was likely art of a collection and is completely preserved without use marks.
The KDH Leipzig (Kurt-Dieter Huffziger Foto- und Kinozubehör) accessories set included:
-A panoramic tripod head
-A set of three extension tubes M42x1)
- A big aluminum shade hood (screw-on 49mm) for wide-angle lens.
- A M42x1 metal body cap in its original box.
- An accessory shoe fitting the the Praktica IV eye piece.

On Saturday November 29, 2025, Lyon, France, I loaded my beloved Leica M3 (year 1956, see details below about the camera) with a 24-pose Kentmere 200 film. After lunch, I just went my close neighborhood for a small photo session. After my stay at the hospital, I am still careful about my physical condition and I preferred to stay close to home for first new photowalk.
The Leitz Summicron 2/5cm was equipped with a Leitz Leica E39 « Dunkelgelb » (dark yellow type 1, Ref. Leitz HOOBE or 13086 H) and the original Leitz Leica shade hood IROOA. Light metering was done using a Minolta Autometer III (1985) equipped either with a 10° finder for selective metering privileging the shadow area’s. The filter light absorption was compensated by metering for 125 ISO instead of 200.

After completion to view Nr. 25 the film was processed using Adox Adonal developer at 1+25 dilution, 20°C, for 10min.
Digitizing was made using a Sony A7 camera (ILCE-7, 24MP) fitted to a Minolta Auto Bellows III with the Minolta slide duplication accessory and Minolta Macro Bellow lens 1:3.5 f=50mm. The diffuse light source was a LED panel CineStill Cine-lite.
The RAW files obtained were inverted within the latest version of Adobe Lightroom 15 (15.0.1, November 2025) 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.
About the camera and the lens :
This Leica M3 circa 1956 (Ref. Leitz ISUMO), double stroke, was sold to me with a Leitz Wetzlar Summicron collapsible normal lens 1:2 f=5cm of the same period equipped with a 39mm screw-on protective filter, a 42mm push-on Leica lens cap and an original Leitz shade hood (Ref. Leitz IROOA).
The camera was serviced in Paris, France, in 2018 by Gérard Métrot at Photo-Suffren, (a Leica boutique) who worked on the maintenance of camera's of famous French photographers as Henri Cartier-Bresson and Robert Doisneau. The camera was inspected by Odéon-Photo, Paris, another historic Leica place in Paris, in April 2024.
I sourced at the same time in Germany a stunning Leitz Leica leather bag (Ref; Leitz IDCOO) of the same model that appeared on the back cover page go the Leica brochure year 1954. This bag can accommodate the camera and a mounted Leica-Meter type M. The interior in covered with a carmin velvet in perfect condition.
The Leica M3 is one of the most iconic range-finder 35mm camera of the 50's and the 60's. It was produced in Wetzlar, Germany, in different versions at 226178 exemplars, between 1954 (n° 700000) and 1966 (n° 1164865, www.summilux.net/materiel/Leica-M3) . The Leica M3 was the result of the study of a "super-Leica" that was started before WWII and only achieved in the 50'S.
The greater improvement of the M3 compared the classical Leica's was in a magnificent and very complex range-finder combined to the view finder permitting the framing with the two eyes open, integrating the frame in the real and normal vision. The shutter integrates too the normal and the slow speeds in the same barillet. The film advance of this version of Leica M3 is also the typical "double-stroke" advance that was exclusive to the Leica M3 first versions.
The camera was transported to me from Paris to Lyon, France on April 26, 2024 and the bag arrived the day after.

As a second roll of black-and-white film with my new camera Pentax 17 (see below for the details about the camera), I loaded a 36- exposure Rollei Retro 80S cartridge and exposed the film for its nominal 80 ISO over several days from April 23 to 29, 2025 in Lyon city, France and surroundings.
The Pentax 17 was equipped with an Anti-UV or a Yellow x2 40.5mm Hoya HMC filter as indicated below . For the camera transportation, I used a small camera bag ThinkTank « Mirrorless Mover 5 » that was well protecting the camera from possibly damaging vibrations when using my bicycle.
The expositions were automatically metered by the camera system using the « P » program modes with, or without, flash. For very bright scenes the exposition was corrected by +0.3 to +1EV to compensate the biais induced (and reversely -0.3 to 0.7 EV for very dark scenes to objects). Since 80 ISO is not in the ISO scale of the Pentax 17 (we can select only 100 or 50), I used the 100 ISO value plus 0.3EV on the correction dial, giving the correct exposure value for the Rollei 80S. The Pentax 117 light sensors are being the filter and the filter is then automatically compensated.
The Rollei Retro 80S (that is an Agfa Aviphot film) black-and-white film is a super-panchromatic film further sensitized in the red up to the near infra-red (760nm) film for technical, industrial and aerial photography, giving in particular valuable contrasts differentiating many different varieties of vegetation and reducing the atmospheric haze as well. The red is however much more bright than a regular panchromatic film. The film is coated on a clear polyester teraphtalate (PET) base with anti-scratch and anti-halation layers that dissolve in the developer during the chemical processing of the film.

After completion (74 frames), the film was processed using Adox Adonal developer at 1+50 dilution for 14min at 20°C.
Single-frame digitizing was made using a Sony A7 camera (ILCE-7, 24MP) fitted to a Minolta Auto Bellows III with the Minolta slide duplication accessory and Minolta Macro Bellow lens 1:3.5 f=50mm at approximate reproduction ratio of 1:2. The diffuse light source was a LED panel CineStill Cine-lite.
The RAW files obtained were inverted within the latest version available of Adobe Lightroom Classic (version 14.3) and edited to the final jpeg pictures without intermediate file. They are presented either as printer files with a frame or the full size JPEG's together with some documentary smartphone color pictures.
About the camera :
Since last Christmas 2024, it was on display in the middle of « reusable » cheap camera’s in the window of my local photography store. But this camera is not cheap and sold at 10-times the price of those « reusable » film camera’s. The Pentax 17 is a novel film camera released by Pentax (a brand belonging to Ricoh Imaging, Japan) in June 2024.
The history of « Pentax » name is still something worth to mention. After the WWII, in Dresden (that was heavily destroyed by the bombing of Feb. 13-15, 1945), Germany, The Zeiss Ikon company could not produce anymore the legendary original Contax (a high-reputation professional range-finder 35mm released in 30’s) camera that was taken by Russia and transferred to Kiev, Ukraine, in the USSR. However the brand name Contax survived and the German engineers designed something completely new within several years : the Contax S (S for « Spiegel mirror reflex ») that integrated a pentaprism for a full redressed reflex viewer observation. Zeiss Ikon Dresden registered to new trademarks derived from the words « Pentaprism » and « Contax » that were « Pentax » and « Pentacon ». If Pentacon became the new name of the company in Dresden, the trademark Pentax was bought by Asahi Optical Company in Japan, and became a formidable industrial and commercial success. Asahi Pentax, then Pentax alone, produced amazing quality camera’s including the legendary « Spotmatic » (a 35mm SLR) and stunning medium-format camera’s heavily used by professional photographers. Many of these camera’s of the past century are still operative and appreciated by film photography enthusiast’s.
Production of film camera’s vanished progressively in the mid 2000’s, as digital camera’s became of better quality and finally of generalized appliances in photography. The Pentax 17 was introduced to the market in June 2024, it was a big surprise for all the film photography lovers. Seeing a newly engineered brand-new film camera was a sort of renaissance of the film photography today of a growing interest worldwide.
The camera is a « half-frame » format on the traditional double-perforated 35mm film giving 17x24mm photograms. This format was not as popular as to classical 24x36mm (full-frame) format of most of the 35mm camera’s. However famous and quality half-frame camera’s were produced in the past including, the long series of Olympus Pen for example. Then, the Pentax 17 immediately attracted the attention of experimented film photographers and camera collectors, probably more than the officially targeted customers of the younger generations. Less than a year after, the future of the Pentax 17 and the film photography project of Pentax is questioned today. The chef-engineer who conducted the project in Ricoh company recently left and the marketing of Pentax 17 is now a question.
This finally decided me to buy an exemplary from my local shop and to discover this strange machine. The camera is of course guaranteed, even with a there-year extension after the camera registration on the Pentax website. The whole ergonomic is clearly derived from classical past 35mm camera’s with a fully mechanical film advance and rewind, a collimated Albada viewer, no digital display at all, only levers, barrels, crank and wheels… However inside is a automatic electronic exposure system with flash, the focusing is manual but the electronic mechanism moves the whole optical group with a micro motor.
The lens is a Cooke triplet 1:3.5 f=25mm equivalent to a 37mm of a 24x36mm format. The Cooke triplet is a photographic lens designed and patented in 1893 by Dennis Taylor who was employed as chief engineer by T. Cooke & Sons of York. It was the first lens system that allowed the elimination of most of the optical distortion or aberration at the outer edge of the image. It likely for this reason that the lens is unscripted curiously « Traditional » on the front lens ring… It is known that a Cooke triplet lens could give surprisingly good results with only three separated optical elements. The Cooke Triplet is still widely used in inexpensive cameras, including variations using aspheric elements, particularly in cell-phone cameras. The Cooke triplet consists of three separated lenses positioned at the finite distance. It is often considered that the triplet is one of the most important discoveries in the field of photographic objectives
The lens receives 40.5mm diameter thread filters that I use for my Zorki / Leningrad lenses Jupiter-8 2/50mm, Jupiter-11 4/135mm and Jupiter-12 2.8/35mm. The metal shade hood Minolta D42KA could mounted on the filter but I have to check is there is vignette induced.
The camera size is close to the original dimensions of a thread-mount Leica (called also the original Barnack Leica) which are, in a way, a sort of « Gold » size in the 35mm camera’s. I compared with my Zorki 1D year 1954 that is a straight reproduction of the Leica Iic. The upper deck of Pentax 17 is designed very clearly as a classical 35mm and we even find the original logo of Asahi Optical Company. The rewind crank is also a revival of past design seen on old Pentax SLR as my year-1971 Spotmatic SP in this seres of pictures.
The Pentax 17 is very light (about 300g) compared to those old ancestors that weight easily the double or the triple. It is then an effortless camera to carry. The Pentax 17 fits in the small ThinkTank bag (called « Mirorless Mover 5 ») that I recently bought to safely carry a film back of my Hasselblad or my Bronica 6X6 camera’s. In this tiny bag, the camera is protected for the element and vibrations due to cycling for instance.

Key features and specifications
* Half-frame image capture (17 x 24mm)
* 37mm (equiv.) FOV F3.5 lens
* Zone focusing system with 6 zones
* Circular leaf shutter (F3.5-16)
* Built-in flash (6m/20ft at ISO100)
* Optical tunnel viewfinder with frame lines
* Exposure from 1/350 sec to 4 sec (+ Bulb)
* Supports films from ISO 50 to ISO 3200
Specifically the lens has:
1. HD coating, which maintains high performance of the lens, by using this PENTAX multi-coating. This also enables high contrast and high definition right to the edges.
2. SP coating (Super Protect) which helps to repel water and oil from the lens.
The fact that the focusing on the Pentax 17 is electronic i.e. the lens only moves when you half-press the shutter gives me faith that autofocus was already considered in the R&D stage.
