Hama 70077 – UV and Protection Filter

The Hama 70077 is a premium UV protection filter designed for 7.7 cm (77 mm) camera lenses. Crafted from high‑quality optical glass, it delivers reliable ultraviolet absorption while preserving image clarity and contrast.

Key Features at a Glance

• Diameter: 7.7 cm (77 mm)
• Material: Optical glass
• Color: Black (neutral)
• Coating: Dual‑layer anti‑reflection, O‑Haze technology
• UV Absorption: UV‑390 (filters wavelengths below 390 nm)
• Protection: Shields lens from dust, fingerprints and accidental scratches
• Compatibility: Fits standard 77 mm front‑thread lenses for both photography and videography

Optical Design & Performance

The filter’s optical glass is engineered to match the refractive index of typical camera lens elements, ensuring minimal distortion or chromatic aberration. The dual‑layer anti‑reflection coating reduces flare by up to 90 %, while the O‑Haze layer further suppresses ghosting and enhances contrast.

Dual‑Layer Anti‑Reflection Coating

The two‑coat system is specifically calibrated for 77 mm lenses. The first coat minimizes surface reflections, whereas the second coat provides additional protection against environmental factors such as moisture and dust. Together they maintain a high transmission rate of visible light, preserving sharpness and color fidelity.

UV‑390 Absorption

The filter blocks ultraviolet radiation below 390 nm, which can otherwise cause haze or degrade image quality over time. By absorbing these wavelengths, the Hama 70077 protects both the lens coating and the sensor from potential UV damage.

Design & Build Quality

The filter’s black finish offers a neutral aesthetic that blends seamlessly with any camera setup. Its robust construction ensures durability during field use, while the smooth front thread allows for quick attachment or removal without compromising alignment.

Compatibility Overview

• Lens Types: Prime and zoom lenses with a 77 mm front thread
• Camera Formats: Full‑frame, APS‑C, APS‑S, and mirrorless systems that accept 77 mm filters
• Video Lenses: Suitable for both still photography and video recording due to its optical clarity and anti‑flare properties

Installation & Usage Tips

1. Clean the Lens Thread: Before attaching, wipe the lens front thread with a microfiber cloth to remove dust.
2. Screw On Carefully: Align the filter’s threads with the lens and rotate clockwise until snug. Avoid over‑tightening to prevent damage.
3. Check for Alignment: Ensure the filter sits flush against the lens surface; any gap can introduce vignetting.
4. Use a Lens Hood: Pairing the filter with a compatible hood further reduces flare and protects from accidental contact.

Care & Maintenance

• Cleaning Solution: Use distilled water or a mild lens cleaning solution. Avoid household cleaners that may contain alcohol or ammonia.
• Soft Cloth: Apply gently with a microfiber cloth in a circular motion.
• Storage: When not in use, store the filter in its protective case to prevent scratches.

Frequently Asked Questions

Does this filter affect color balance?

No. The dual‑layer coating and O‑Haze technology are designed to preserve natural colors while eliminating UV interference.

Can I use it on a 77 mm lens with a different brand?

Yes, the filter is compatible with any standard 77 mm front‑thread lens regardless of manufacturer.

Will it introduce flare in low‑light conditions?

The anti‑reflection coating significantly reduces flare, making it suitable for both bright and dim environments.

Is there a risk of scratching the filter surface?

While the glass is durable, avoid contact with abrasive materials. Use a protective case when transporting.
