Durst Duca

A Tiny Full‑Frame Surprise: Shooting the Durst Duca

My Durst Duca camera.

I first saw the Durst Duca in McKeown's Camera Guide probably 30 years ago, and I can still remember my first instinct: this had to be a miniature camera. The tall, narrow body looked more like a tiny cine camera than anything that could handle standard 35mm film. With its vertical form, I assumed it used a 16mm cassette like a Minolta 16. So when I read that the Duca is actually a full‑frame 35mm camera, I was shocked.

 It just didn't seem possible. The camera looked too small and too skinny to hide a 35mm cassette sideways, especially with that unusual vertical format. For years, it stayed in the back of my mind as one of those oddball cameras I never expected to actually run across.

Finding My Duca

Being in the U.S., this little Italian camera rarely shows up at the usual places I haunt for gear—flea markets, garage sales, estate sales. On the big auction sites, I do see them once in a while. Still, they're usually priced higher than I'm willing to pay, especially once you tack on international shipping.

 When the auction was about to end, I logged in about 10 minutes before the finish. The price on the Duca had jumped up a bit, and I was outbid, so I nudged my max up—still on the low side—and watched the timer count down. No one else jumped in, and I ended up winning the camera.

The auction house shipped quickly. When I opened the box, I was still surprised by how small the camera is in person. It was even smaller than I'd pictured. I started to check it over, winding the advance lever on the side and cocking the shutter. I heard a faint click, but it was so quiet I wasn't sure the shutter was actually opening and closing.

 I pulled the side of the camera off to get at the film chamber and saw that one of the two film cassettes was still inside—that was a nice bonus, since it meant I only needed to scare up one more cassette. Digging around in the drawer where I keep odds and ends of camera accessories, I found another cassette that would work.

 In my darkroom, I shone a flashlight through the lens and fired the shutter. At first, I saw no light at all, and my heart sank; I figured the camera might be dead. Then I noticed the pressure plate that holds the film flat against the rails. I pulled the pressure plate out, pointed the flashlight into the front of the lens again, and tripped the shutter. This time, I saw a brief flash of light through the gate—success. The shutter was working. That was the moment I decided the Durst Duca would be the camera I'd write about for this week's blog.

A Little Durst History

Durst is best known today for its darkroom enlargers. Still, for about 25 years, the company also made a small, innovative line of cameras that reflected the same experimental mindset they brought to the darkroom. Founded in 1936 in northern Italy by brothers Julius and Gilbert Durst, the firm quickly gravitated toward photographic equipment, especially enlargers, which eventually became its main business.

 Durst's camera story starts with the Gil, a simple 120 roll‑film box camera introduced in 1938 for the growing amateur market. After World War II, Durst resumed production of the Gil and then shifted toward more compact designs, setting the stage for its 35mm experiments.

The Duca followed as a tiny 35mm still camera that used Agfa Karat cassettes instead of standard 35mm cartridges. That choice let Durst play with miniaturized body shapes: an oval, cine‑style form in a pocketable size, offered in several colors. This focus on unusual styling and packaging mirrored their enlargers, which often looked different from competitors but emphasized precision and usability.

 Next came the Durst 66, a modestly specified camera with an unconventional shutter and a quirky way of measuring exposure. You can already see Durst thinking outside the box, trying to rethink mechanisms rather than just copying others' work.

 All of that leads to the Durst Automatica, made from 1956 to 1963 and often regarded as the first 35mm camera with aperture‑priority automatic exposure. It used a pneumatic shutter derived from the Durst 66 and wrapped it in a very elegant body. For such a small camera line, it was an ambitious finale and shows how far Durst was willing to push design and automation.

My Durst Duca

The Durst Duca was introduced at the Milan Trade Fair in September 1946 and stayed in production until around 1952. It's a vertical‑format, full‑frame 35mm camera that uses Agfa Karat cassettes, and it was available in five colors: black, blue, red, white, and brown. I've only ever seen the black, blue, and red versions in photos. Still, now that I know more are out there, I'll keep an eye out—even if I suspect the more unusual colors will be priced higher than I'm willing to pay.

Physically, the Duca is tiny: only about 4 inches tall by 3.25 inches deep and just over 1.5 inches wide, and it weighs 10.1 ounces with the cassettes in place. The body is nicely rounded and fits well in the hand—definitely a camera you could drop in a coat pocket and forget about until you need it.

 The camera is very basic. The lens is a fixed 5 cm, f/11 meniscus design, though a rarer f/8 version is supposed to exist. Shutter speeds are limited to just two settings: 1/30 of a second and "P" for timed exposures. A small switch on the camera's faceplate, just below the viewfinder, sets the speed. I've also seen a version where the speeds are marked "I" for instant and "T" for timed. My guess is that mine is a later version, but I can't say that for sure.

 Focusing is done in only two zones. You can set the lens for 1–3 meters or 3 meters to infinity. To focus, you turn the outer ring of the lens until the red line points to the distance you want.

Loading Film and Getting the Duca Ready

To open the camera for loading, there's a small curled‑up lip on the right side of the body that you lift to swing open the film door. Inside, you'll see the two Agfa Karat cassettes. They pop out along with the pressure plate, which sits just behind the film gate and pulls straight up and out for loading.

 As mentioned, the camera takes Agfa Karat cassettes. When these were sold new, each roll of 35mm film was cut for 12 exposures, and the front of the camera proudly states that it takes 12 photos per roll. Since I have bulk 35mm film and two cassettes, I loaded my own.

I put one of the cassettes and my bulk loader into a dark bag. Inside the bag, I opened the loader, pulled out what I guessed would be enough film for 12 exposures, and added a bit more to be safe. I fed the film into the first cassette and closed up the loader, leaving a short length to thread into the second cassette. Then I unzipped the dark bag and removed the loaded cassette.

In the light, I could now feed the end of the film from the first cassette into the second one, slide both cassettes into the side of the camera, and drop the pressure plate back into place, making sure the film sat flat against the gate. Before closing the door, I advanced the film a bit to confirm that it was transporting. With the cassettes and pressure plate removed earlier, I'd noticed a small brass pin—very similar to the one in the Ansco Memo—that pops out, grabs a film sprocket, and moves up to advance the film.

Once everything looked right, I swung the back door into position and pressed it firmly against the body. Two small notches on the back have to line up with the body; if they're off even a little, the door won't sit snugly.

 Before heading out, I took a look at the lens and saw that the front element was pretty grimy. With some lens cleaner and tissues, I managed to clean the front, but because the camera is built the way it is, I couldn't get to the rear element at all. With the film loaded and the transport confirmed, I was ready to go for a walk through the neighborhood.

 

Shooting with a Vertical 35mm

With film in the camera, I headed out around the neighborhood, trying to photograph some of the same subjects I usually shoot—houses, parked cars, trees, little details I run across on my walks.

 The camera's faceplate shows a horizontal rectangle next to the number 12, while the viewfinder is vertical. I found that confusing at first. Was this meant to be a horizontal or a vertical camera? With only 12 exposures per roll, it seemed logical that they'd be in a horizontal orientation to match most 35mm cameras. Still, the vertical viewfinder was telling me otherwise. I wasn't sure, so I shot in both orientations early on, turning the camera back and forth.

 Once I processed the film and looked through the negatives, it was obvious: the Duca is a vertical‑format camera. If you want a horizontal image, you turn the whole camera on its side. It's not complicated, but it does take a little mental adjustment when you're used to most 35mm cameras being the other way around.

Results and Thoughts

Some of the images turned out great, and some didn't. There are a few reasons for that. One is focus—I didn't always remember to switch between the two focus zones when I changed subject distance. The other is exposure. With only one shutter speed and one aperture, you're basically at the mercy of the light. The negatives showed some variation, but nothing I couldn't deal with in post‑processing. It reminded me a lot of shooting with an Instamatic: pick a film with a wide exposure latitude and let it do the heavy lifting.

 I got 14 frames on the roll before the film refused to advance into the second cassette, which tells me my length estimate in the dark bag was close. The camera itself handled well. The viewfinder is on the small side and can be difficult to look through, especially if you wear glasses, but it's usable once you get used to it.

 The transport worked smoothly, and the shutter opened and closed as it should. The lens, however, is still dirty on the rear element, and there's really no easy way to clean it without taking the camera apart. That shows up in the photos as a general softness, almost like shooting with a soft‑focus filter. On some subjects, the look can actually be pleasant; on others, it just makes things a bit mushy.

 Overall, the Duca was a fun camera to use, and I'll definitely shoot it again. The whole process—from loading the Karat cassettes, to working with the vertical format, to seeing the results—was enjoyable. It's the kind of camera you could toss in a pocket when you head out on a trip and forget about until something catches your eye. I like that it's doing all of this as a full‑frame 35mm camera in such a tiny body.

 Thanks for taking the time to read about my experience with this little Italian wonder of a camera.

Voigtlander Prominent 35mm

My father-in laws Voigtlander Prominent

I'm unsure if I'll be able to get another posting out before the beginning of 2026, since Christmas and New Year's fall on the day I generally publish my reviews. Since this might be the final post for 2025, I wanted to make it a special review. 

 Special in the sense that, while the Voigtländer Prominent is an outstanding camera, what makes this camera especially special to me is that my father-in-law owned it, so it holds an even greater, much more cherished place in my collection.

 Let me tell you a bit about my father-in-law. He was the oldest of seven children living in a very small town named Sugar Creek, MO, just outside Independence. They were not a wealthy family, as the father worked at the local refinery. I was told that the house was so small that some of the children had to sleep in closets. At 18, he married my mother-in-law, who was only 17 at the time. By the time he was 22 and my mother-in-law was 21, they had three children.

 Soon after they were married, he joined the Army, where they were stationed in Augusta, GA, where my wife and the third child were born.  When my wife was only 6 months old, my father-in-law and the family were transferred to Naples, Italy. With his wife and three young children, my wife moved to Italy.

My father-in-law always had a passion for photography and, from what I'm told, purchased the Voigtländer Prominent while stationed overseas. After their time in Italy,  the family moved back to the USA. At this point, my father-in-law found a local camera store back near Kansas City, where he honed his photographic skills using the Voigtländer Prominent he purchased overseas.

 After the camera store, he was hired by Procter & Gamble to sell Duncan Hines cake mixes. He climbed the corporate ladder, moving his family with each promotion due to his outstanding managerial and sales skills. All the while, he still had a passion for photography. He was always taking photos of the family and eventually ended his career as a top executive at some of the largest Fortune 500 companies.

 This article is not only about a truly amazing camera, but also an ode to my father-in-law. Someone I looked up to in my career helped me in so many ways and was a warm, loving, generous, and caring individual. He passed away way too early from an auto accident, almost 30 years ago. We still have his Voigtländer Prominent, which he used, and it's in remarkable condition. For the final post, I wanted to write about this truly excellent camera, which means so much to all the family members.

 I've had the opportunity to purchase other Voigtländer prominent cameras, both the original and the Prominent II, with the standard Ultron and Heliar lenses, along with many different lenses and accessories for their cameras. Still, the camera from my father-in-law is off-limits. It will stay in my collection until I'm no longer around.

 I've reviewed other Voigtländer cameras, so I've written about their history in the past. Let me focus on the history of Voigtländer in a specific timeframe: after World War II, when they rebuilt a fantastic camera brand.

Voigtlander Post World War II:

 Voigtländer emerged from the Second World War with its Braunschweig factory largely intact and quickly resumed work under British military oversight, initially dedicating much of its output to Allied reparations until the new West German currency was introduced in 1949. This relatively undamaged industrial base, combined with a strong pre‑war optical tradition, allowed the firm to re‑establish itself rapidly as a key player in the post‑war German camera industry.​

 In the immediate post‑war years, Voigtländer revived and modernized pre‑war designs, adding new anti‑reflection coatings to lenses and continuing large‑format and medium‑format lens production. The company remained under the ownership of the chemicals and photographic‑paper firm Schering AG, which had acquired it in the 1920s, providing financial stability in a challenging economic climate.​

 The 1950s became Voigtländer's golden decade, marked by a broad range of high‑quality cameras and lenses that cemented its international reputation. Compact 35mm lines such as the Vito and the more sophisticated Vitessa appeared alongside the professional Prominent 35mm rangefinder. At the same time, optics like the Ultron, Nokton, Apo‑Lanthar, and Heliar established the brand as a leader in lens design. In 1952, Voigtländer introduced the Apo‑Lanthar 105 mm f/4.5, and in 1959, it launched the 36–82 mm f/2.8 Zoomar, one of the first interchangeable zoom lenses for 35mm still photography.​

 In 1956, Schering sold Voigtländer to the Carl Zeiss Foundation, bringing it into the same corporate orbit as Zeiss Ikon while initially keeping manufacturing and sales structures separate. Throughout the late 1950s and early 1960s, Voigtländer expanded into leaf‑shutter SLRs and advanced models such as the Bessamatic and Ultramatic, but the cameras were complex and costly to build. As Japanese manufacturers increased efficiency and undercut prices, Voigtländer's high production costs and conservative designs became major competitive disadvantages.​

 In 1965, Zeiss‑Ikon and Voigtländer's sales operations were combined, but falling sales led to the decision to cease camera production and close the Braunschweig factory on 4 August 1971, affecting over 2,000 employees. The physical works were reorganized as Optische Werke Voigtländer, with shared ownership between Zeiss, Rollei, and the state of Lower Saxony. By 1974, Rollei had taken complete control, continuing to produce lenses and cameras under the Voigtländer brand until its own financial collapse in the early 1980s.

 The trademark then passed through German photo retailers and, from 1999, has been licensed to Cosina in Japan, which uses the historic name on modern manual‑focus lenses and niche film cameras, giving Voigtländer a new life in the era of digital photography.

My Camera:

 My Voigtländer Prominent comes with the standard Ultron 50mm f/2.0 lens. The camera body serial # B 46551, and lens serial # 3782651. With this camera, there is a Voigtländer UV filter that I generally leave on the camera, along with a yellow filter for black-and-white photography, a rectangular metal lens hood, and the fitted brown camera case. The camera is 5.5" wide by 3.5" tall by 3.5" deep, and weighs 2 pounds, 0.8 ounces without film.

 The Voigtländer Prominent has some weight to it, and for me, it feels very comfortable in my hands. Maybe because it resembles an SLR more, like what most people are used to with rangefinder cameras. The camera has a somewhat peculiar layout and is something you'll need to get used to.

When you put the camera to your eye, the viewfinder is on the right side of the camera, which, for many, is different. The majority of cameras have the viewfinder either centered or more to the left than to the right. The focusing ring isn't on the lens, but located on the rewind knob. As you turn the outside of the rewind knob, generally used to rewind the film in the film cassette when you're done with the roll, on the Voigtländer Prominent, it focuses the lens. 

Looking through the viewfinder, the rangefinder is bright, with the yellowed area in the center clearly visible. With your left hand, turn the outer ring of the rewind knob to focus on your subject. Once the image is in focus, take your photo. Under the focus distance is the camera's depth of field guide for the aperture used. 

To take a photo, on the right-hand side of the camera is the film advance lever; wind it clockwise to advance the film. The same motion that advances the film also moves an internal bar that cocks the shutter. The shutter speed dial on the Syncro-Compur shutter is set by turning a ring just in front of the shutter cocking lever. The shutter speeds on this camera go from 1/500 to 1 sec, with "B" for timed exposures. According to the Voigtländer Prominent camera manual, it's best to set the 1/500 shutter speed before winding the camera, which cocks the shutter. You can set any shutter speed once the camera's shutter is cocked, but 1/500's not recommended.

If you want to use the camera's self-timer, it can be manually set by pulling down on the shutter's cocking lever once the camera is cocked. This sets the camera's self-timer to approximately 10 seconds when the shutter release is depressed. The camera's shutter release is the larger button on the top of the camera, just to the left of the film transport knob. Behind the shutter release is the cable release socket for timed exposures.

Looking at the lens, the aperture is set by turning the aperture ring in the direction that produces a properly exposed image. On the Ultron 50mm lens, the aperture goes from F/2.0 to F/16. To remove the lens from the body, on the bottom of the lens is a large button you press in; interestingly, you can remove the lens by turning it left or right. Likewise, to put the lens onto the camera body, make sure the large button is on the bottom. You can mount the lens either to the right or left as long as the button end is on the bottom.

 Since the camera utilizes a leaf-style shutter as opposed to the standard focal plane shutter, the flash will sync at any shutter speed, which allows the photographer the ability to control the ambient light with flash much better, and this makes film cameras such as Hasselblad and Rolleiflex cameras ideal for weddings, portraiture, and commercial studio work. On the front of the camera, at the 11:00 position, is the PC sync for flash, along with the flash settings: "X" for electronic flash or "M" for flash bulbs.

To load film into the Voigtländer Prominent camera, on the left side of the camera are two buttons you press to open the camera's back door. Once open, you load the 35mm film just as you would any other 35mm camera. Push up the rewind shaft, drop in the 35mm cassette, and bring the leader over to the camera's take-up spool. Thread the leader into the take-up spool slot and wind the film advance. Make sure the film's sprocket holes are in the drive gears and take up the slack. Before closing the back of the film door, I like to turn the rewind knob to take up the slack in the film cassette, so when I close the back and wind to the first frame, I watch the rewind knob turn to make sure the film is actually moving within the camera.

 Once you close the back door, the frame counter needs to be set manually. To do this, lift up on the winding knob, then turn the camera's frame counter to "F" to give you a couple of turns on the film advance until you get to frame number 1.

When you're done with the roll of film, you'll need to rewind it into the film cassette. The rewind knob has an arrow pointing outward. Push the button outwards, and the rewind handle will pop up. Just below the cable release socket is a small button labeled "R". Press the "R" button to disengage the transport gear, then turn the rewind knob clockwise to rewind the film into the film cassette. Once the film is rewound, open the camera back, process the film, and reload the camera with more film. 

 

My Results:

 I loaded the Voigtländer Prominent with a roll of 200-speed film and took one of our dogs to the local dog park to get the pooch some exercise, taking photos of a different area than walking through the neighborhood as I usually do.

 Here are some photos from the local dog park and the shadows on my back patio on a beautifully sunny day in the Portland Area in December. It wasn't a typical December day in this area, so I wanted to make the most of it.

Conclusion:

 I really love this camera. The images are incredibly sharp, and this camera gives Leica and Contax a run for their money. It's exceptionally well-built, the lenses are tremendous, and I like the camera's size and weight.

 The system's weakest link is its lack of lenses, and for many, the camera's focus is a drawback. I've read that people don't like having the viewfinder on the right side, which makes it more challenging for them to use the camera. I don't find it annoying, as others do.
