Medium format cameras like these are prized for their detail and tonal range, making them favorites for professionals and enthusiasts alike. Let’s break down what makes each one special and how they compare.

Mamiya RB67 vs RB67 Pro S Comparison

Overview of the Mamiya RB67

The Mamiya RB67 is a beast of a camera. Its all-metal body feels like it could survive anything, built to last decades. It uses 120 or 220 film, producing those gorgeous 6×7 cm negatives that capture incredible detail. The design is straightforward: manual film advance, shutter cocking, and a rotating back for seamless switching between portrait and landscape orientations.

I’ll never forget my first shoot with the RB67. It was a portrait session in a dimly lit studio, and the weight of the camera made me feel like I was holding a piece of history. The satisfying click of the shutter and the smooth lens operation were addictive. The results were breathtaking—rich shadows and smooth gradients that 35mm film just can’t match. It’s a camera that demands patience but rewards you with stunning images.

The RB67 is all about reliability. Being fully mechanical, it doesn’t need batteries, which is perfect for remote shoots where power isn’t an option. Loading film can be tricky at first—you need to ensure it’s seated correctly to avoid blank frames. But once you master it, it’s second nature. I’ve had a few mishaps early on, but now I can load it with my eyes closed.

One thing to watch for is the foam seals in older models. Over time, they can degrade, leading to light leaks. I had to replace the seals on my RB67 once, but it’s a small price to pay for such a reliable workhorse. This camera is ideal for photographers who value simplicity and durability over extra features.

Overview of the Mamiya RB67 Pro S

The RB67 Pro S takes everything great about the original and refines it. Released in 1974, it introduced upgrades that make it more user-friendly and versatile. The standout feature is the multi-format backs, allowing you to shoot frame sizes like 6×4.5 or 6×8 without changing the back. It also has advanced safety features to prevent accidental exposures, which is a lifesaver during critical shoots.

When I first used the Pro S, I was blown away by its flexibility. I was shooting a wedding and needed to switch between 6×7 and 6×4.5 formats mid-shoot for different looks. The ability to change formats seamlessly opened up new creative possibilities. The safety mechanisms ensured I never double-exposed a frame by mistake, which is crucial when every shot counts.

The Pro S also has a quieter mirror and a brighter viewfinder, making composition easier, especially in low light. Being a later model, it often has less wear on critical components like film seals. While early RB67s can suffer from degraded seals, the Pro S is typically in better condition, especially from later production runs. I’ve never had a light leak issue with my Pro S, which speaks to its improved build quality.

Another perk is the refined ergonomics. The grip feels slightly more comfortable, and the overall design is a bit more polished. It’s still a heavy camera, but it feels just a tad less cumbersome than its predecessor. For photographers who want modern conveniences without sacrificing medium format quality, the Pro S is a fantastic choice.

Detailed Comparison

Design and Build

Both cameras are built to last, with all-metal bodies that feel indestructible. The RB67 has a classic, rugged look that exudes durability—it’s like holding a piece of art. The Pro S shares this robust construction but adds subtle ergonomic improvements, like a better grip, which makes it slightly easier to handle. Both are primarily studio tools due to their size and weight, but they can be used in the field with a tripod.

I’ve seen RB67s from the 1970s still working perfectly. I once dropped my RB67 from a low table, and it didn’t even flinch—no damage at all. The Pro S feels just as tough but a bit more refined, with a smoother film advance lever. Both have quirks, like the tricky film loading process, but they become intuitive with practice. For example, the RB67’s film advance requires a bit more effort compared to the Pro S’s smoother action.

The weight difference is noticeable but not drastic. The RB67 feels slightly heavier, which can be tiring during long shoots. The Pro S, while still hefty, has a better balance that makes it a bit more comfortable for extended use. If you’re shooting in a controlled environment, either will serve you well, but the Pro S’s refinements make it a touch more user-friendly.

Features

The Pro S shines in its feature set. Its multi-format backs let you experiment with frame sizes like 6×4.5 or 6×8, which is great for creative flexibility. I used this feature extensively during a portrait and landscape project where I needed different formats for various purposes. The RB67 is fixed at 6×7, which is fantastic for consistency but limits versatility if you need other sizes.

The Pro S also has advanced safety features, like double-exposure prevention and a lock to ensure the dark slide is removed before shooting. I’ve had moments with the RB67 where I accidentally double-exposed a frame because I wasn’t paying attention, especially during fast-paced shoots. The Pro S’s safety mechanisms eliminate that risk, which is a huge relief. The brighter viewfinder and orientation indicator also make composition easier, especially in low light. I struggled to compose shots with the RB67 in dim conditions, but the Pro S made it a breeze.

Another key upgrade is the improved film back system. Early RB67s had foam seals that could rot, leading to light leaks. While the Pro S still uses foam in some areas, later models are less prone to this issue, and the Pro SD (a later version) eliminated foam seals entirely. I’ve had to replace the seals on my RB67 once, which was a hassle, but my Pro S has been trouble-free.

Performance

When it comes to image quality, both cameras are exceptional. The 6×7 cm negative size delivers incredible detail and tonal range, perfect for large prints or detailed scans. I’ve had prints made from both cameras, and they’re indistinguishable in terms of quality. The Pro S has access to newer lenses with better coatings, which can reduce flare and improve contrast in certain conditions. For example, when shooting backlit portraits, the Pro S’s lenses handled the light better, reducing flare compared to some older RB67 lenses.

However, for most practical purposes, the difference is minimal. I’ve shot with both in various settings—portraits, landscapes, and studio work—and the results are always stunning. The RB67’s images have a timeless quality, while the Pro S’s newer lenses might give a slight edge in harsh lighting. Unless you’re pixel-peeping, you won’t notice much difference. Both are ideal for photographers who value quality over speed.

The shutter speed tops out at 1/400 sec for both, which is sufficient for most medium format work but not ideal for fast action. The mechanical reliability of both cameras is impressive, with the RB67’s fully manual operation being particularly robust. The Pro S, while still mechanical, feels a bit more polished in its operation, with a smoother shutter release.

Handling

The Pro S handles a bit better than the RB67. Its film advance is smoother, and the shutter feels more precise. Both cameras share the rotating back feature, which is a game-changer for tripod work, letting you switch between portrait and landscape orientations without moving the camera. I use this feature all the time in the studio—it saves so much time and hassle.

The Pro S’s lighter weight and improved grip make it slightly more comfortable for handheld shooting, though both are heavy and best suited for tripod-based work. I’ve used both for long sessions, and while both can be fatiguing, the Pro S feels just a tad less so. The balance is better, and the grip helps stabilize it when shooting handheld, which I do occasionally for more dynamic shots. For example, I’ve used the Pro S handheld for street photography, and while it’s not ideal, the grip made it manageable.

The RB67, while solid, can feel a bit clunky in comparison. Its film advance lever requires more effort, and the overall handling is less refined. Still, once you’re used to it, it’s a joy to use, especially for deliberate, composed shots. Both cameras reward a methodical approach, but the Pro S feels a bit more forgiving.

Lenses

Mamiya’s lens lineup for the RB67 system is impressive, ranging from 37mm wide-angle to 500mm telephoto. The 90mm f/3.8 is my go-to for portraits—it offers a field of view similar to a 50mm lens on 35mm format but with medium format’s superior detail. I’ve used it for everything from headshots to environmental portraits, and the bokeh is smooth and pleasing. The Pro S has access to even more lenses, including the KL series, known for their exceptional optical quality. I’ve tried the 127mm f/3.8 SWD on the Pro S, and it’s sharp as a tack, even wide open.

Lens compatibility is a major strength. Both cameras use the same mount, so all RB67 lenses work on both models. The Pro S, being newer, benefits from later lens designs with improved coatings, which can enhance performance in challenging lighting conditions. For instance, when shooting in foggy conditions, the coated lenses on the Pro S reduced ghosting and flare compared to some older lenses. I’ve also used the 50mm f/4.5 for landscapes, and the results are stunning on both cameras, with edge-to-edge sharpness.

The lens system’s modularity is a big plus. You can swap lenses quickly, and the leaf shutter design means you can use flash at any shutter speed, which is great for studio work. I’ve used this feature for fashion shoots, syncing with strobes to freeze motion perfectly. Whether you’re shooting wide-angle landscapes or tight portraits, the lens options for both cameras are versatile and high-quality.
