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.

Welta Superfekta

My Welta Superfekta camera

Not being wealthy, my collecting has always been focused on cameras well within our family's financial means. Up until my final ten years of working and before retirement, the cameras I purchased were items you could find at local flea markets and estate sales, or occasionally I made a trade for an item while selling at a camera show where I had a table.

 Being drawn to obscure and unusual cameras and having devoured McKeown's Camera Guide for many years, the Welta Superfekta is one camera I've always dreamed of adding to my collection. Due to its price and relative scarcity in the U.S., it's always been out of reach for me until this past few years.

 It wasn't until I looked at an online camera auction that I found the Welta Superfekta at a price that was not only reasonable but also inexpensive. Online, the camera looked in good to decent condition, but they said the shutter was erratic. To me, those words mean I'll need to send the camera in for a shutter repair, which isn't too uncommon for a camera reaching 100 years old. 

 I purchased the Welta Superfekta online, and when the camera arrived, as suspected, its shutter was extremely sluggish and needed to be CLA'd. I reached out to the person I usually send cameras for servicing, and he confirmed he could service the shutter but wasn't sure about other areas of the camera, as he wasn't too familiar with it.

The excitement of adding the Welta Superfekta to my collection was wonderful, especially since it's a 6x9 cm-format camera that takes 120 film. Still, the more exciting part of the camera is that it's very similar to the Cornu Ontoflex, which has a rotating back, allowing the photographer to shoot both vertically and horizontally without turning the camera sideways. Just rotate the back from vertical to horizontal and flip the image orientation, as with the Mamiya RB67.

 The one thing I noticed when I turned my camera from vertical to horizontal is that the back doesn't turn all the way, which makes me curious about its history. This flaw, while concerning, adds character and a story to the camera, resonating with collectors who appreciate Imperfections.  

Another reason for my excitement to add the Welta Superfekta to my collection is that it would be the third folding Twin Lens camera in my collection. I had already purchased and written about both the Welta Perfekta and the Zeh Zeca-Flex cameras, making this the “Trifecta” of this camera style.

Welta before World War II:

 The history of Welta Kamerawerke leading up to World War II is a testament to the rapid innovation and high-precision craftsmanship that defined the German photographic industry in the early 20th century. Founded in 1914 by Walter Waurich and Theodor Weber in Freital, near Dresden, the company began as "Waurich & Weber" before adopting the "Welta" brand name that would eventually become synonymous with high-end folding cameras.

 In its first decade, Welta focused on the transition from heavy glass-plate cameras to the more versatile roll-film formats. By the 1920s, Freital and the surrounding Dresden area had become the global epicenter of camera manufacturing, and Welta held its own against giants like Zeiss Ikon. Their early success was built on the folding camera—a design that allowed a high-quality lens and shutter to collapse into a slim, leather-covered metal body.

 The 1930s marked Welta's "Golden Era." During this decade, the company moved beyond standard designs to create some of the most mechanically complex cameras ever made. While competitors were focusing on the emerging 35mm trend, Welta mastered the 120 roll-film market with innovative models like:

 

  • The Weltur: A rangefinder folding camera known for its incredible build quality and integrated viewfinders.

  • The Perfekta and Superfekta: These folding Twin Lens Reflex (TLR) cameras were engineering marvels, offering the ground-glass focusing of a studio camera in a portable, collapsing frame.

  • The Welti: A foray into the 35mm market that proved Welta could compete with the Leica in terms of precision and optics, often featuring high-end Carl Zeiss Jena or Schneider lenses.

 Welta's pre-war philosophy was to offer a variety of price points without sacrificing mechanical integrity. You could find a simple Welta Trio for the casual hobbyist, or a Superfekta with a rotating back for the professional who demanded perfection. This versatility allowed Welta to export heavily to the UK and the United States, where their cameras were often rebranded for local retailers.

 By the late 1930s, Welta was a premier name in photography. However, as Germany shifted toward a war economy, production began to pivot away from consumer optics. After the war, Freital was part of the Soviet occupation zone (later East Germany), and Welta was eventually absorbed into the state-owned VEB Pentacon, marking the end of its era as an independent, family-founded innovator.

My Camera:

 My Welta Superfekta camera is 7.5" tall without the light chimney opened, and 10" with it opened, by 4" wide, and 3.5" deep with the body retracted, and 6.25" deep when the body of the camera is extended. The camera weighs 3 pounds, 0.2 ounces without film, so it has some heft.

To extend the camera body away from the film chamber, press the silver button on the right side of the camera body, located just below the film winding lever. Pressing the button quickly extends the camera lens area, and you'll be able to see the bellows. By doing so, you'll see how the camera gets its name, a folding twin-lens camera. When I extended the camera's front from the rear, I noticed the bellows were in excellent light-tight condition.

 My camera has a 7.5cm f/3.5 Weltaskop viewing lens, along with a Carl Zeiss Jena 10.5 F/3.5 Tessar taking lens, so the viewing lens is wider than the taking lens, and the taking lens is in a Compur-Rapid shutter with shutter speeds from 1/400 to 1 sec. along with "B", and "T". The focus lever is located on the left side of the lens when you're holding the camera, and it slides up and down to focus on your subject. 

There is also a focus scale along the top of the camera, between the Welta sign on the film body and the Superfekta sign on the lens area. As you slide the focus lever up and down, you'll see a triangle move from side to side, indicating the distance to the subject on the focus scale, which is in meters.

 Along the back of the camera, by the viewfinder, there is a button to press to open the light chimney. The light chimney popped up, and along one side is a depth-of-field scale for the camera, and on the front is the magnifying lens, which flips as it should. 

On the back of the film body is another sliding lever that you move to the left, in the direction of the arrow, and the back will open. Opening the back of the camera, I noticed that the film advance roller, which activates the frame counter, is missing, so the frame counter isn't operational on this camera. Luckily, there is a red window on the back door so you can see the numbers being transported as you roll the film from one image to the next. 

 I also noticed a paper sign glued to the inside of the back door at the top, which read, "non si girare il rullo che nel senso della freccia" (translation from Italian to English: "do not turn the roller in the direction of the arrow").  This message on the inside tells me the camera is originally from Italy. I guess the camera was made for the Italian market, but the reseller may have added that; I'm not certain. Still, it's interesting that a German camera was sold in Italy and found its way to the USA.

To load the camera with film, the chamber where you put in a fresh roll of film pulls up to make it easier to put in the film, which is a nice feature in the camera. Otherwise, the camera loads just like many roll film cameras, but it would have been nice to have a frame counter that advances from the roller on the back to indicate the frame numbers. I'll just have to do it the "old-fashioned" way and look through the red window to get to the next frame when I shoot.

To collapse the camera lens area into the camera body, you'll need to press in two silver buttons on the front of the camera, placed between the viewing and taking lens, and press the lens area into the film body, which is extended by a couple of scissor struts on each side of the camera. Be sure to retract the camera stand leg, under the front lens area, just behind the tripod socket, before closing the camera. If you don't do this, the camera will not close. I know because I've tried a few times by accident.

 When you close the camera, another interesting thing is that there's a roller at the tip of the film area on the outside. When you close the lens into the film body, the viewfinder rolls along the roller, sliding it forward and covering the focus scale. Given that the camera is almost 100 years old, it's still interesting how it opens and closes mechanically. 

If you don't want to rotate the film chamber when shooting, there is a flip-up sports-type finder on the side of the camera you can use if that's easier for taking horizontal images. It just gives the photographer another option when using the camera.

 

My Results:

 I don't have a case that fits my Welta Superfekta camera. The camera doesn't have the standard loops you can snap into a carrying strap, so when I went out shooting a few times, I just put it in a pouch-style case to carry it and took it out when I was ready to shoot.

 Looking at the side of the camera, there are a couple of studs and other areas where a strap might fit, but without a manual or a nomenclature for the items on the camera, I'm unsure what they are used for.

 I took the Welta Superfekta out a couple of times to shoot with: once to a local lake and another time while walking around the neighborhood to get closer-up images.

 Here are the results from my two times using the camera.

Conclusion:

 The camera's results underwhelmed me, as one of two things is happening. First, I didn't think the images would be as sharp as I had imagined; that may be because something happened to the camera, like a drop or impact, which is also why the camera doesn't flip all the way horizontally when shooting. 

 My weakening eyesight may also cause it, but because of eye surgery I had last year on my right and dominant eye, I'm becoming more and more dependent on using my left eye for focusing, which is difficult for me at times. Personally, I feel it's more the first issue: something tweaked the camera body, and the lens doesn't align properly, which is why I wanted to shoot the second, more close-up images walking through the neighborhood.

 Nonetheless, it's somewhat awkward to hold without a neck strap to keep it steady. Still, I absolutely love the camera's ability to rotate the film back for both vertical and horizontal photography. It's a wonderful camera to have in my collection, and for the price paid, even with the servicing, it's still a bargain.
