Color Correction

The Rodenstock 100mm f/4 Apo-Sironar HR Digital Lens is a **large format prime** designed for use with **technical and view cameras**, mounting via a **Lens Board (Technical Camera)** system. With a fixed **100mm focal length** and a **maximum aperture of f/4**, this lens is built for deliberate, high-precision photographic work where image quality and control take priority. Focus is entirely **manual**, in keeping with large format shooting discipline. The lens is notably compact for its format at just **250g**, and its **49mm filter thread** makes it straightforward to attach polarizing or ND filters. There is **no image stabilization**, so use with a stable support system is expected. This is a purpose-built optic for professionals operating within the large format and technical camera ecosystem, particularly those working alongside digital backs.

Apochromatic correction minimizes chromatic aberration across the frame, critical for extracting full detail from high-resolution digital backs.

Fixed 100mm focal length sits in the standard range for large format, making it versatile across studio, architectural, and product photography.

Large Format Prime, 100mm

The HR (High Resolution) designation indicates the optical formula is specifically corrected for the micro-lenses and sensor characteristics of modern digital backs.

Optimized for Digital Backs

Provides a practical balance of light gathering and depth of field control for technical camera workflows typically used on a tripod or studio stand.

f/4 Maximum Aperture

Mounts via a standard lens board system, ensuring broad compatibility with technical and view cameras from makers such as Linhof, Arca-Swiss, and Cambo.

Lens Board Mount

Deliberate manual focus control is standard for large format photography, supporting precise focus placement for demanding commercial and architectural work.

Manual Focus Construction

Accepts standard 49mm filters, making it straightforward to add polarizers, ND filters, or other accessories without specialist adapters.

49mm Filter Thread

Relatively lightweight for a large format lens, reducing strain on the camera's front standard and overall system weight.
