1. ആമുഖം
The Hama UV Filter 390 HTMC Multi-Coated 67mm is an essential accessory for DSLR camera lenses. It serves a dual purpose: protecting your valuable lens and improving image quality by managing ultraviolet light.
പ്രധാന സവിശേഷതകൾ:
- UV Absorption: Effectively absorbs ultraviolet rays up to 390 nm, reducing haze and preventing fuzziness in photographs.
- ലെൻസ് സംരക്ഷണം: Acts as a physical barrier, safeguarding the front element of your camera lens from scratches, dust, fingerprints, and minor impacts.
- HTMC Multi-Coating: Features an 8-layer HTMC (High Transmission Multi-Coating) on each side, ensuring high light transmission and minimizing reflections.
- Neutral Colour: Designed to be color-neutral, ensuring no color cast is introduced into your images.
- നീണ്ടുനിൽക്കുന്ന നിർമ്മാണം: Made with high-quality lens glass and a robust metal mount.

3. സജ്ജീകരണവും ഇൻസ്റ്റാളേഷനും
Installing the Hama UV Filter 390 is a straightforward process. Ensure your camera lens has a 67mm filter thread for proper compatibility.
ഇൻസ്റ്റലേഷൻ ഘട്ടങ്ങൾ:
- Identify Lens Thread Size: Locate the filter thread size on your camera lens. This is usually printed on the front of the lens barrel or on the inside of the lens cap. Confirm it is 67mm.
- ലെൻസ് ക്യാപ്പ് നീക്കം ചെയ്യുക: Carefully remove the front lens cap from your camera lens.
- Align Filter: Hold the Hama UV Filter 390 with the threaded side facing the lens. Align the filter's threads with the threads on the front of your lens.
- സ്ക്രൂ ഓൺ: Gently turn the filter clockwise. Ensure it threads smoothly without forcing it. If you encounter resistance, unscrew, realign, and try again. Cross-threading can damage both the filter and your lens.
- Tighten Gently: Once the filter is fully threaded, tighten it just enough so it is secure. Avoid over-tightening, as this can make it difficult to remove later.
The filter is now installed and ready for use. You can typically attach your lens cap or lens hood directly onto the filter's front thread.
4. പ്രവർത്തന തത്വങ്ങൾ
The Hama UV Filter 390 operates by selectively absorbing ultraviolet light, which is invisible to the human eye but can affect photographic images, especially in bright, outdoor conditions or at high altitudes.
ഇത് എങ്ങനെ പ്രവർത്തിക്കുന്നു:
- UV Light Reduction: The filter's specialized glass and coating absorb UV radiation, preventing it from reaching the camera sensor. This reduces atmospheric haze and improves clarity and contrast in distant subjects.
- ശാരീരിക സംരക്ഷണം: Beyond optical benefits, the filter acts as a sacrificial layer. In the event of accidental bumps, scratches, or exposure to dust and moisture, the filter bears the brunt, protecting the more expensive front element of your lens.
- Multi-Coating Benefits: The HTMC (8x) multi-coating minimizes internal reflections and flare, ensuring that the filter itself does not degrade image quality by introducing unwanted light artifacts.

5. പരിപാലനവും പരിചരണവും
Proper maintenance ensures the longevity and optimal performance of your Hama UV Filter 390.
ക്ലീനിംഗ് നിർദ്ദേശങ്ങൾ:
- പൊടി നീക്കം: Use a soft lens brush or a blower to remove loose dust particles from the filter surface.
- വിരലടയാളങ്ങൾ/അടയാളങ്ങൾ: For stubborn marks, apply a small amount of lens cleaning solution to a clean, soft microfiber cloth. Gently wipe the filter surface in a circular motion from the center outwards.
- കഠിനമായ രാസവസ്തുക്കൾ ഒഴിവാക്കുക: Do not use abrasive cleaners, solvents, or harsh chemicals, as these can damage the multi-coating.
- Clean Cloths: Always use clean, lint-free cloths specifically designed for optical surfaces.
സംഭരണം:
- When not in use, store the filter in its protective case to prevent dust accumulation and accidental damage.
- Keep the filter in a dry, cool environment, away from direct sunlight and extreme temperatures.
6. പ്രശ്നപരിഹാരം
If you encounter issues with your Hama UV Filter 390, refer to the following common problems and solutions.
| പ്രശ്നം | സാധ്യമായ കാരണം | പരിഹാരം |
|---|---|---|
| Filter will not screw onto lens. | Incorrect thread size or cross-threading. | Verify lens thread size is 67mm. Realign the filter carefully and turn gently to avoid cross-threading. |
| Image quality appears degraded (e.g., blurry, soft). | Dirty filter surface or excessive reflections. | Clean the filter thoroughly using recommended methods. Ensure the filter is securely attached. |
| Filter is stuck on the lens. | Over-tightened or thermal expansion/contraction. | Try using a rubber grip or a filter wrench for gentle removal. Avoid excessive force. |
| Vignetting (dark corners in images). | Using multiple filters or a wide-angle lens. | This filter has a slim mount to minimize vignetting. If it occurs, consider removing other filters or using a wider lens hood. |
