The Soligor C/D 500mm f/8 is a compact, manual-focus, mirror (catadioptric) telephoto lens known for its long reach and distinctive "donut" bokeh, using mirrors instead of traditional glass elements, often featuring a T-Mount for wide camera compatibility (like Canon, Nikon, Olympus, Pentax via adapters) and sometimes marketed with close-focus/macro capabilities, requiring steady hands or tripods due to its fixed f/8 aperture and long focal length for sharp results, making it great for wildlife or distant subjects. 

Key Characteristics:

• Type: Mirror (Reflex) Lens.

• Focal Length: 500mm (long telephoto).

• Aperture: Fixed at f/8 (though some variants might show f/8-12), often with an f/8 setting for shooting.

• Focus: Manual Focus only.

• Mount: Typically uses a T-Mount system, requiring specific adapters for different camera brands (e.g., Nikon F, Canon FD/FL, Olympus OM).

• Design: Compact and lighter than traditional 500mm lenses due to its mirror design, producing unique out-of-focus highlights (bokeh).

• Use Cases: Excellent for birding, wildlife, sports, or even macro photography due to its close focusing ability, but needs good light and stability. 

What to Expect:

• "Donut" Bokeh: The circular mirrors create distinct ring-shaped out-of-focus highlights.

• Sharpness: Can be sharp, but requires careful manual focusing and often a tripod to overcome camera shake at 500mm.

• Versatility: Adaptable to many cameras, offering extreme magnification for compact size. 

Extremely nice near mint condition lens. Very carefully cared for. Barrel of lens is very clean and clear with no marks, dents, scratches or any noticeable damage.  You can only tell on the mount that it has been attached to a camera.  Glass is clean and clear.  No scratches, cleaning marks, fungus, separation or notable dust.  A beautiful piece of equipment. The lens includes front cap, t-mouny to Pentax adapter and rear lens cap.
