Hey everyone! As a professional photographer who’s spent countless hours with medium format cameras, I’m thrilled to dive deep into one of the most debated topics in the film photography world: Mamiya RB67 vs RB67 Pro S.
I’ve personally shot with both cameras extensively over the years, and let me tell you – while they might look similar at first glance, there are some crucial differences that can make or break your shooting experience. Whether you’re a seasoned film photographer or just dipping your toes into the beautiful world of medium format, understanding these differences will help you make the right choice for your photography journey.
So grab a cup of coffee, and let’s break down everything you need to know about these legendary cameras from Mamiya.
What Exactly is the Mamiya RB67 System?
Before we jump into the comparison, let me explain what makes the RB67 system so special. The RB67 is Mamiya’s legendary 6×7 medium format SLR camera system, first introduced in 1970. The name “RB” stands for “Rotating Back” – a brilliant design feature that lets you switch between horizontal and vertical compositions without rotating the entire camera.
I fell in love with medium format photography when I discovered the incredible detail and tonality that 6×7 negatives provide. There’s something magical about holding a 6×7 transparency up to the light – the detail is absolutely stunning compared to 35mm film.
The RB67 system is built like a tank and is fully mechanical, meaning it doesn’t require batteries to operate. This reliability has made it a favorite among professional photographers for decades. I’ve taken my RB67 on countless shoots, from studio portraits to landscape expeditions, and it has never let me down.
Quick Overview: RB67 Pro vs RB67 Pro S
Let me give you the quick rundown before we dive into the nitty-gritty details:
Mamiya RB67 Pro (Original) was introduced in 1970 as the first model in the series. It’s a basic, no-frills workhorse that delivers exceptional image quality.
Mamiya RB67 Pro S came along in 1974 with several key improvements that made it more user-friendly and reliable, especially for field work.
Now, let’s get into the detailed comparison that’ll help you understand which one is right for you.
Key Differences: What Really Matters?
After shooting extensively with both models, I’ve discovered that while the differences might seem minor on paper, they can have a significant impact on your shooting experience. Let me break down the most important differences I’ve encountered.
Double Exposure Prevention: A Game-Changer
This is arguably the most significant difference between the two models, and it’s something I’ve learned to appreciate the hard way.
RB67 Pro (Original): The original model has no double exposure prevention. This means you can accidentally take multiple exposures on the same frame if you’re not careful. I learned this lesson the hard way during a wedding shoot early in my career – I accidentally double-exposed a crucial moment, and let me tell you, that’s not a phone call you want to make to a client!
RB67 Pro S: The Pro S introduced a double exposure interlock system that prevents you from taking another exposure until you’ve advanced the film. This feature alone makes the Pro S worth the extra cost in my opinion. However, if you DO want to create intentional double exposures, the Pro S has a dedicated multiple exposure lever on the film back that you can engage to override the interlock.
Orientation Indicator: Small But Mighty
This might seem like a minor feature, but trust me, it’s something you’ll appreciate in real-world shooting situations.
RB67 Pro (Original): The original model lacks a clear orientation indicator. While some early models had this feature printed on the rotating back, many didn’t, making it easy to lose track of whether you’re shooting in landscape or portrait orientation.
RB67 Pro S: The Pro S includes a clear orientation indicator that shows you whether you’re in landscape or portrait mode. This might sound trivial, but when you’re in the middle of a shoot and quickly switching between orientations, having this visual cue is incredibly helpful. I’ve found it especially useful during portrait sessions when I’m switching between horizontal and vertical compositions frequently.
Focusing Hood: Quality of Life Improvement
The focusing hood is something you’ll interact with constantly, so the differences here are worth noting.
RB67 Pro (Original): The original model has a manual focusing hood that requires you to collapse all four sides independently. This can be a bit fiddly, especially when you’re in a hurry or working in tight spaces.
RB67 Pro S: The Pro S features a self-erecting focusing hood that’s much easier to use. You can collapse it with a simple pinch of the sides, making it much more convenient for field work. The magnifier also completely covers the finder opening, reducing stray light and making it easier to focus accurately.
I discovered how much of a difference this makes during a landscape photography trip in Scotland. I was working in windy conditions, and being able to quickly collapse and extend the focusing hood on my Pro S made the difference between getting the shot and missing it.
Focus Lock: Precision Matters
When you’re working with medium format, precise focus is crucial, and this is another area where the Pro S shines.
RB67 Pro (Original): The original model lacks a focus lock, which means your focus settings can drift if you bump the camera or during transport.
RB67 Pro S: The Pro S includes a focus lock lever located below the left-hand focus knob. This allows you to lock your focus settings once you’ve achieved perfect focus, preventing accidental changes. I’ve found this invaluable for studio work where I need to maintain consistent focus throughout a session.
Film Back System: Reliability and Convenience
The film back system is central to the RB67’s versatility, and there are some important differences here.
RB67 Pro (Original): The original film backs are basic but functional. They lack the sophisticated interlocks of the later model, which means you need to be more careful about your shooting sequence.
RB67 Pro S: The Pro S film backs include improved interlocks and safety features. The shutter cannot be released if the film hasn’t been advanced, preventing accidental blank frames. The multiple exposure system is also more sophisticated, with a dedicated lever that makes intentional multiple exposures easier to create.
Build Quality and Ergonomics: Tank-Like Reliability
Both cameras are built like tanks, but there are some subtle differences in their construction and handling.
Weight and Balance
RB67 Pro (Original): Weighs in at approximately 3.5 lbs (1.6 kg) without a lens. The balance is good, but the camera can feel a bit front-heavy with longer lenses.
RB67 Pro S: Virtually identical in weight and balance to the original. The improvements are internal rather than affecting the overall form factor.
Handling in the Field
I’ve taken both cameras on extensive field trips, and here’s what I’ve discovered:
RB67 Pro (Original): perfectly capable for field work, but you need to be more deliberate and careful with your technique. The lack of interlocks means you need to develop a consistent shooting routine to avoid mistakes.
RB67 Pro S: The additional safety features and quality-of-life improvements make it more forgiving for field work. I’ve found it particularly valuable when shooting portraits or events where things move quickly and you don’t have time to double-check every setting.
Image Quality: What Really Matters
At the end of the day, image quality is what matters most, and I’m happy to report that both cameras deliver exceptional results.
Lens Compatibility
One important thing to note is that both cameras use the same lens mount, so you can use any RB67 lens on either body. The lens system is one of the RB67’s greatest strengths, with excellent optics available in focal lengths from 50mm to 500mm.
I’ve shot with various lenses on both bodies, and the image quality is identical when using the same lens. The differences between the bodies don’t affect the final image quality – they’re all about the shooting experience and reliability.
Real-World Image Quality
Let me share a recent experience that illustrates this point. Last month, I set up a test shoot with both cameras using the same 90mm f/3.8 lens, same film stock (Kodak Portra 400), and same lighting conditions.
The results? Virtually identical image quality. Both cameras produced the stunning detail, beautiful tonality, and rich colors that make 6×7 medium format so special. The only difference was in the shooting experience – the Pro S was more forgiving and easier to work with, especially when I was switching between orientations quickly.
Practical Considerations: Which One Should You Choose?
Now that we’ve covered all the technical details, let me help you decide which camera is right for your specific needs.
Studio Photographers
If you primarily work in a studio environment with static subjects, the original RB67 Pro might be all you need. In a controlled studio setting, you have time to be deliberate with your technique, and the lack of interlocks is less likely to cause problems.
I’ve used both cameras extensively in studio settings, and while I prefer the Pro S for its convenience, the original model certainly gets the job done. If you’re on a tight budget, the original RB67 Pro can save you some money that you could invest in better lenses or lighting equipment.
Field and Portrait Photographers
If you plan to use your camera in the field or for portrait work where subjects might move, I strongly recommend the RB67 Pro S. The additional safety features and quality-of-life improvements make a significant difference in real-world shooting situations.
I discovered this during a portrait session last year. I was shooting with both cameras to test them, and when my subject moved unexpectedly, the Pro S’s interlocks prevented me from making mistakes that would have ruined shots on the original model.
Landscape Photographers
For landscape photography, both cameras work well, but I give a slight edge to the Pro S. The focus lock is particularly valuable for landscape work where you might set up your shot and then wait for the perfect light.
During a recent landscape photography workshop, I was shooting sunrise scenes with my Pro S, and the focus lock gave me confidence that my settings wouldn’t change while I was waiting for the light to be just right.

Wedding and Event Photographers
If you’re shooting weddings or events, the RB67 Pro S is definitely the way to go. The pace of event photography means you don’t have time to baby-sit your camera, and the Pro S’s safety features can prevent costly mistakes.
I learned this lesson early in my career when I was shooting a wedding with an original RB67 Pro and accidentally double-exposed a crucial moment. While the couple was understanding, it was a stressful situation that could have been avoided with a Pro S.
Cost Considerations: Value for Money
Let’s talk about the financial aspect, because this is an important consideration for most photographers.
Current Market Prices (as of 2025)
RB67 Pro (Original): You can typically find a complete kit with body, lens, and back for $400-600 on eBay, or $500-700 from a camera store with a warranty.
RB67 Pro S: Expect to pay $500-700 on eBay, or $600-800 from a store with a warranty.
Is the Pro S Worth the Extra Cost?
In my opinion, yes – the Pro S is worth the extra $100-200 for most photographers. The improved reliability and convenience features more than justify the small price difference, especially if you plan to use the camera professionally or for important personal projects.
However, if you’re on a very tight budget or primarily shoot in a controlled studio environment, the original RB67 Pro still delivers exceptional image quality and can save you some money.
Maintenance and Longevity: Built to Last
Both cameras are built to last, but there are some considerations for long-term ownership.
Common Issues
RB67 Pro (Original): The main issues to watch for are light seal deterioration and mirror damping foam degradation. These are relatively easy and inexpensive to fix.
RB67 Pro S: Same issues as the original, plus you need to ensure that the interlock mechanisms are functioning properly. The additional complexity means there are more things that can potentially go wrong, but in my experience, Pro S cameras are generally very reliable if they’ve been properly maintained.
Parts and Service
One advantage of the RB67 system is that parts are still relatively available, and there are technicians who can service these cameras. However, as these cameras get older, this may become more challenging.
I’ve had both my cameras serviced over the years, and I’ve found that qualified technicians can keep them running beautifully for decades with proper care.
My Personal Experience: Stories from the Field
Let me share some personal experiences that might help you understand the real-world differences between these cameras.
The Wedding Disaster
Early in my career, I was shooting a wedding with my original RB67 Pro. Everything was going smoothly until the ceremony, when I accidentally double-exposed a crucial moment – the bride’s father walking her down the aisle. I was devastated, and while I managed to salvage the situation with other shots, it was a stressful lesson in the importance of double exposure prevention.
After that experience, I invested in a Pro S, and I’ve never had that problem again. The peace of mind alone is worth the extra cost.
The Landscape Adventure
Last year, I took both cameras on a landscape photography trip to the Scottish Highlands. I wanted to test them side by side in challenging conditions.
During the trip, I discovered that the Pro S’s focus lock was invaluable for landscape work. I could set up my composition, lock the focus, and then wait for the perfect light without worrying about bumping the focus knobs.
The orientation indicator also proved surprisingly useful. When I was working in low light conditions, being able to quickly glance at the indicator to confirm my orientation saved me from several potential mistakes.
The Portrait Session
I recently did a portrait session where I used both cameras to compare them directly. I was shooting a busy executive who didn’t have much time, so I needed to work quickly and efficiently.
The Pro S’s self-erecting focusing hood made a significant difference in this situation. I could quickly check my focus and composition without fumbling with the hood, allowing me to maintain a good flow with my subject.
The double exposure prevention also gave me confidence to work more quickly, knowing that I wouldn’t accidentally ruin any frames.
