Fujifilm Acros II: The Case for the Finest-Grain Black and White Film Available
PhotographyThe conversation around black and white film grain almost always lands on Kodak T-Max 100 as the reference point. Fujifilm Acros II offers a meaningful counterargument — and the RMS numbers back it up.
Why This Category Matters
Fine-grain black and white films are experiencing renewed demand among photographers using medium format and 35mm alongside digital systems. The drivers are consistent: tonal range, archival quality, and the haptic experience of a workflow that forces slowing down. For shooters committed to that workflow, the choice of film stock at ISO 100 is a real decision with measurable differences.
What Makes Acros II Different
RMS granularity: 7. This is the headline number. RMS (Root Mean Square) granularity measures the statistical variation in density across a film surface — lower numbers mean finer, more uniform grain. T-Max 100, long considered the fine-grain reference for 35mm, measures RMS 8. Acros II at RMS 7 is measurably finer.
ISO 100. Acros II is a daylight-speed film, which means it performs best in bright conditions or with longer exposures. The fine grain is a consequence of the slow speed — the same tradeoff as T-Max 100, Delta 100, or Rollei RPX 100.
Reciprocity behavior. This is where Acros II genuinely earns its reputation among long-exposure shooters. For exposures between 2 and 16 minutes, Acros II requires only a 1/2 stop of additional exposure compensation. Most black and white films require significantly more — often 1 to 2 full stops for exposures beyond a few seconds, plus a compensating development adjustment. The reduced reciprocity failure makes Acros II unusually forgiving for nightscapes, architecture, and any work involving exposures beyond a few seconds.
Available formats: 35mm and 120. Acros II is not available in 4x5 or larger sheet film formats. Large-format shooters working in black and white at ISO 100 will need to look elsewhere — T-Max 100 remains the leading option with 4x5 availability.
Who It’s For
Acros II is a strong choice if you’re shooting predominantly 35mm or 120, working in conditions where ISO 100 is adequate, and want the finest grain available in those formats. The reciprocity advantage makes it particularly compelling for any long-exposure work — if you’re shooting cityscapes at night, architectural details with ND filters, or landscapes at dusk, the 1/2 stop reciprocity compensation simplifies your exposure math considerably.
It’s not the right choice if you need 4x5 availability, regularly shoot in lower light where push processing would be necessary, or prioritize speed over grain.
The So What
Acros II has a specific set of properties that are best-in-class: finest RMS granularity available in 35mm and 120, exceptional reciprocity behavior for long exposures, and excellent tonal range at ISO 100. For photographers whose work fits those conditions, the film is difficult to beat. T-Max 100 remains a strong alternative — especially where 4x5 is needed — but Acros II’s grain advantage is real and consistently reproducible.
