With a nominal sensitivity of ISO 25/15°, this orthochromatically sensitised film excels in various demanding applications. It has an impressive sensitivity reserve of up to two apertures, depending on the development process, making it a versatile choice for both scientific and artistic photography.

This film is particularly well-suited for situations where detail and accuracy are paramount. It produces strong contrast and high tonal sensitivity, especially in medium format. Whether you’re capturing technical images, charismatic portraits, high-contrast still lifes, or stunning landscapes, the Rollei Ortho 25 Plus delivers outstanding results.

Joshua L. ★★★★★

Shot this at box speed on a bright day and the tonality is just beautiful — those midtones really pop. The lack of grain even in the shadows surprised me for such a slow film.

Mia Q. ★★★★★

The grain is virtually non-existent in my enlargements, the sharpness is incredible for a slow film. I shot a few test rolls at ISO 25 and the tonal range in bright sun was exactly what I wanted for fine art prints.

Hazel ★★★★★

I was skeptical about a 25-speed film at first, but the sharpness on my negatives is honestly stunning. It handled fine-grained detail better than I expected, though you'll definitely want a tripod or bright sunlight to get the most out of that ISO.
