Removing Dust from a Leitz Elmarit 90mm Lens
The Leitz Elmarit 90mm lens is a popular choice for photographers due to its sharpness, portability, and versatility. However, its design, with the lens set deep within a narrow tube, can make dust removal challenging. This blog post will guide you through a safe and effective technique for removing dust from the rear lens surface of a Leitz Elmarit 90mm lens.
Understanding the Challenge
The rear element of the Leitz Elmarit 90mm lens is recessed deep within the lens barrel. This recessed design, while aesthetically pleasing, makes it difficult to access the lens surface for cleaning. Traditional methods like using a lens brush or blower can be ineffective and even risky, as they may dislodge dust particles further into the lens, potentially causing damage.
The Solution: Filtered Compressed Air
The most effective and safest method for removing dust from the rear element of a Leitz Elmarit 90mm lens is using a controlled stream of filtered compressed air. This technique requires a few essential tools:
- Filtered Compressed Air Canister: Use a high-quality canister specifically designed for electronics and photography. Avoid using household air compressors, as they may contain moisture and contaminants that can damage the lens.
- Lens Cleaning Brush: A soft-bristled brush is helpful for removing dust from the lens barrel and surrounding areas.
- Microfiber Cloth: A clean microfiber cloth is useful for wiping away any remaining dust particles.
Step-by-Step Guide
- Prepare the Lens: Before cleaning, ensure the lens is off the camera and the lens cap is removed. Gently brush the lens barrel and surrounding areas with a soft-bristled brush to remove any loose dust.
- Apply Filtered Air: Hold the compressed air canister upright and gently direct a stream of air towards the rear element of the lens. Do not hold the canister too close to the lens, as this can force dust particles further into the lens.
- Angle the Air: To ensure all dust particles are removed, direct the air stream at different angles. Slowly move the canister around the lens, focusing on the recessed areas where dust may accumulate.
- Check for Remaining Dust: After applying compressed air, carefully examine the lens surface for any remaining dust particles. If you see any, repeat steps 2 and 3.
- Final Wipe: If there are still stubborn dust particles, use a clean microfiber cloth to gently wipe the lens surface. Be careful not to apply excessive pressure, as this can damage the lens coating.
Important Considerations
- Avoid direct contact: Never touch the lens surface with your fingers. Oils and fingerprints can damage the lens coating.
- Use filtered air: Always use a filtered compressed air canister designed for electronics and photography. Unfiltered air can contain moisture and contaminants that can damage the lens.
- Gentle pressure: Apply gentle pressure when using compressed air and a microfiber cloth. Excessive force can damage the lens.
- Professional cleaning: If you are unsure about cleaning your lens or if the dust particles are stubborn, consult a professional lens cleaning service.
Conclusion
Removing dust from the rear element of a Leitz Elmarit 90mm lens can be a delicate task. By using filtered compressed air and following these steps, you can effectively remove dust particles without damaging the lens. Remember to always handle your lens with care and seek professional assistance if you are unsure about any cleaning procedure.
