Rodenstock's Rodagon 210mm — premium for very large format enlarging.
The Rodagon 210mm f/5.6 covers 5×7in and 8×10in large format negatives, representing the upper end of the Rodagon range for fine-art large format printing. This focal length requires a tall enlarger column and a dedicated darkroom space for the print distances involved.
210mm focal length, f/5.6 maximum aperture, Rodenstock multi-coated, M39 thread mount, designed for 5×7in to 8×10in large format negatives.
For 8×10in large format printing, the Rodagon 210mm is among the larger premium options. The image projection geometry at this focal length demands precise alignment of the enlarger head. Sharpness at f/8–f/11 is excellent. Competes with the Schneider Componon 210mm for professional large format work.
Inspect for fungus and haze — large element lenses are more susceptible. Confirm M39 thread and lensboard compatibility. Aperture blades should be clean and operate smoothly.
