Boyer Paris Apo-Saphir 180mm f/10 – Apochromatic Large Format / Process Barrel Lens

Hailing from the workshops of Paris, the Boyer Apo-Saphir is a masterclass in French optical engineering. Originally designed as a process lens for ultra-precise reproduction, its symmetric Dialyte construction makes it a hidden gem for large-format photographers and macro enthusiasts. This lens doesn’t just capture light; it renders images with a clinical, apochromatic clarity and a flat field that modern “character” lenses often lack. It is a piece of functional history that provides a bridge between early 20th-century technical precision and contemporary large-format art. The Technicals (The “Specs”): Manufacturer: Boyer Paris (France). Model: Apo-Saphir (Apochromatic). Focal Length: 180mm. Maximum Aperture: f/10. Aperture Range: f/10 to f/90 (Ideal for deep depth-of-field work). Optical Design: 4-element, 4-group Dialyte type (Symmetrical). Condition: Excellent vintage barrel condition. The iris moves smoothly via the external lever, and the 12 blade diaphragm creates a perfectly circular aperture for exquisite out-of-focus highlights. Glass: Clear and free of fungus or separation. Typical internal micro-dust consistent with age, which does not impact optical performance. Mounting: This is a barrel lens; it requires a shutter (like a Packard or behind-the-lens shutter) or can be adapted for digital macro use via bellows. Shipping: Tested and shipped securely from the Netherlands.
