Rollei RPX 100 120: The Medium Format Film Roll for Surgical Sharpness
If you're looking to capture infinite textures with your medium format camera, the Rollei RPX 100 120 is your definitive emulsion. This black and white film stands out for its exceptionally fine grain and a sharpness that squeezes every line out of your lenses. It is the preferred choice for landscape and portrait photographers who demand a classic look with an impeccable professional aesthetic.
What makes the Rollei RPX 100 in 120 format special?
Unlike other emulsions, the Rollei RPX 100 offers a nominal sensitivity of ISO 100 with a surprising exposure latitude. Its polyester base guarantees superior physical stability, facilitating flat drying and hassle-free scanning. When shooting in 120, the tonal richness of this film is multiplied, offering deep blacks and bright highlights with a transition of grays that seems to have no end.

Technical Specifications: The DNA of the Rollei RPX 100
To master this film, it is vital to understand its chemical and physical behavior. Here are the technical data you need to expose with precision in your next analog project.
| Feature | Technical Detail |
|---|---|
| Film Type | Panchromatic Black and White |
| Sensitivity | ISO 100 / 21° DIN |
| Film Base | Transparent polyester (0.10 mm) |
| Granularity | RMS 9.0 (Very fine grain) |
Technical Variables of the Film
- Contrast and Tonal Range: It presents a very balanced medium-high contrast. It doesn't block shadows easily, allowing exquisite detail in dark areas if metered correctly.
- Spectral Sensitivity: Being panchromatic, it records all colors of the visible spectrum naturally, with an excellent response to red or yellow filters for dramatic skies.
- Grain Structure: It uses a traditional but refined emulsion technology. The grain is barely perceptible in large medium format enlargements.
- Acutance: Very high. It defines the edges of objects with a clarity that highlights the depth of field in 6×4.5, 6×6 or 6×7 cameras.
- Resolution: Capable of recording up to 150 lines per mm, which guarantees that you won't lose a single detail of skin or foliage texture.
- Flexibility (Push/Pull): Although its nominal ISO is 100, it responds wonderfully to pushing up to ISO 400 (Push +2) while maintaining a very aesthetic visual noise.
- Antihalation Layer: It incorporates a highly efficient layer that prevents light bleeding in strong backlight situations, keeping edges clean.

Development Times for Rollei RPX 100 (20°C)
The secret to a perfect negative lies in the development time. Based on data from DigitalTruth and our own tests in the Camera Market lab, here are the standard times for ISO 100.
| Developer | Dilution | Time (Min) | Expected Result |
|---|---|---|---|
| Kodak D-76 | Stock | 8:00 | Optimal contrast and fine grain. |
| Rodinal (R09) | 1+25 / 1+50 | 6:00 / 12:00 | Maximum acutance (sharp edges). |
| Ilford ID-11 | 1+1 | 10:00 | Smooth tonal transitions. |
| Kodak HC-110 | Dilution B | 5:00 | Fast and with dense shadows. |
Camera Market Pro Tip: Avoid Drying Marks
A common problem when developing Rollei RPX 100 in 120 format is its polyester base. Being a stiffer and more transparent base than traditional acetate, water droplets are more visible after drying. If you don't use a wetting agent (such as Ilfotol or Photo-Flo) in the final rinse, limescale marks will "stick" to the base and will be a nightmare to remove when scanning.
The correct technique: Use distilled water for the final bath with wetting agent. Do not run your fingers or sponges over the wet emulsion; let gravity do its work in a dust-free place. Rollei RPX 100 dries exceptionally flat, take advantage of it.

Physical Behavior and Scanability
Flatness (Film Curl)
Rollei RPX 100 is a blessing for those who scan at home. Thanks to its polyester base, the film stays as flat as a board. Forget the fight against the "tile" effect that other films have. This means that your scanner's focus (whether flatbed or with a digital camera) will be uniform across the entire medium format negative.
Inversion profiles (Scanning)
When inverting with Negative Lab Pro, select the "Frontier" or "Noritsu" profile to obtain neutral colors. Since its base is very clear, it doesn't have that dominant orange or purple mask. We recommend adjusting the Black Point carefully so as not to lose the wealth of detail that this film holds in the shadows.
At the Limit: Extreme Exposure and the Zone System
Reciprocity Failure
In night or long exposure photography, Rollei RPX 100 behaves predictably. If your light meter indicates 1 second, expose for 2 seconds. If it indicates 10 seconds, you'll need to go up to 30 seconds. It is vital to compensate for the loss of sensitivity to avoid negatives that are too "thin".
Pushing and Underdevelopment
Need more speed? Rollei RPX 100 handles a push to ISO 400 with incredible dignity. Grain increases slightly in size, but contrast becomes more dramatic and "rock 'n' roll", ideal for low-light street photography.
Dynamic Range Map
- Highlights: Retains detail even in skies overexposed by 2 stops.
- Shadows: Very solid down to Zone III. Below that, detail disappears quickly.
- Midtones: Zone V is pure silk, ideal for skin tones in portraiture.

Tip on loading 120 film
We know how frustrating it is to have a film roll fogged due to a handling error. The Rollei RPX 100 120 comes with a high-quality protective paper, but even so, it is sensitive to light fogging from the side if the spool isn't tightened well when taking it out of the camera.
At Camera Market we always recommend loading and unloading the film in dim light or in the shade. When you finish the roll, make sure to lick the adhesive strip well and tighten the roll firmly. This small gesture will save the edges of your photos from those annoying orange flares (or white ones on the negative) that usually ruin frames 1 and 12.

Frequently Asked Questions about Rollei RPX 100 120 (FAQ)
Is the Rollei RPX 100 the same as the old Agfa APX 100?
Not exactly. Although it inherits the philosophy of the legendary Agfa, the RPX 100 is a modern formulation manufactured for Rollei that offers greater base stability and improved acutance. It is a film optimized for digital workflows and high-resolution scanning.
Can I use it in 6×6, 6×7 or 6×9 format cameras?
Absolutely. As it is a standard 120 format film roll, it is fully compatible with any medium format camera on the market, whether a Hasselblad, Mamiya, Bronica, Pentax 67 or even pinhole and toy cameras like the Holga.
What happens if I expose the film roll at ISO 200 by mistake?
Don't worry, it can be fixed. You just have to let us know when sending it to our lab so that we carry out push processing (+1 stop). The RPX 100 emulsion has enough latitude to absorb this adjustment without a significant loss of quality in the negative.
How long does this film roll last once expired?
If stored in a fridge or freezer, it can maintain its properties for years. However, at Camera Market we always send units with ample expiration dates to guarantee that the emulsion does not lose sensitivity or gain base fog over time.
Is it a film suitable for beginners in medium format?
It is, in fact, highly recommended. Its ISO 100 allows shooting in full sun with wide apertures to achieve beautiful blur, and its noble and predictable behavior greatly facilitates learning both in shooting and in home developing.
