Often, photographers ask whether protective lens filters are really necessary. While it is true that lens filters protect the surface of your lens against scratches, dust, moisture and fingerprints, it is important to buy quality filters as ordinary, cheap filters may produce unwanted side effects or reduce image quality.
Premium, clear protective filters
The Benro Super High Digital (SHD) UV range of premium, clear filters are more than just hardened glass. Made from high-quality optic glass with low reflectivity, these filters ensure crisp and clear results. Unlike CPL filters, they have no effect on the image – in fact, a quality protective filter shouldn’t alter the image in any way.
- High-quality optical glass
- High transmittance
- Low reflectivity
- Ultra-thin metal frame
Strong, slim design minimises vignetting
Every element of the design ensures that your lens is protected. It starts with a brass metal ring that is stronger and more durable than the aluminium rings on more affordable filters. They are lens prone to denting and will protect your front element from side impacts too. The thin, 3mm profile of the metal frame minimises the vignetting (dark corners) that is often caused by filters with thick frames.
Multiple coatings for crisp and clear results
Protected within this strong, metal frame is 1.6mm of German-engineered high-quality optic glass. With 16-layers of UCLA (ultra-low chromatic aberration) coatings, every effort has gone into its design to prevent reflection and glare. The multiple coatings absorb harmful UV rays and produce a uniform reflectance curve that does not disrupt the natural colour balance of the image. The coating also repels moisture and oil, making the lens easy to clean.
A wise, reliable investment
Invest in a good quality filter to protect your lens investment. Benro SHD UV lens filters are available in thread sizes ranging from 49mm to 82mm, of which the 77mm filter is most popular as it fits these staple zoom lenses: 16-35mm, 24-70mm and 70-200mm. With multiple, waterproof coatings and an anti-scratch formula, an SHD UV filter is an essential lens accessory.
