For the first film with my new Pentax 17 film camera (see the details about the camera below) , I loaded a Washi-X 100 ISO color film that is likely a Kodak Aerocolor film based on a Kodak Ektar formula coated on a maskless PET (polyester teraphtalate) base, spooled by the French film company Washi. This will give normally 72 views and finally gave 80. Due to the optical properties of PET basis that conduct light from the film leader outside the cartridge, the first 3 frames may have some a blue parasite cast (orange on the positive).
The film was exposed for 100 ISO over 5 consecutive days. The Pentax 17 was equipped with an Anti-UV 40.5mm Hoya HMC filter or, when indicated below, a circular polarizing filter.
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 bicycles.
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).

After completion the film was processed by a local lab service using the standart C-41 color protocol. As a result, all the frames are very nicely exposed with a very remarkable definition and contrast without noticeable flare even without any shade hood used.
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 14.2) 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, 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.

An interesting experiment I did with a 35mm film and a cheap plastic camera. First I took some very random shots, then I reloaded the film and took another set of random cat shots to double expose the film. Once I finished the film I dunked IT in in a pot of boiling water for 3 mins! Amazingly the film survived, although it did take a few days to dry out. Once it was dry I took it to my local minilab and developed it. Some weird results but pretty happy. Give it a go!
