The brand new Ultra Hard Coating (UHC) UV features all the latest and greatest optics and coatings in an aluminium frame at an excellent price. NiSi is coming out of an intense period of R&D, which has seen them rise to the top of the filter market thanks to their True Colour and other technologies.

This new filter offers several features normally found in much more expensive filters.

  • UHD Technology for high resolution sensors | Double-sided high precision polishing ensures a perfect surface, which delivers uncompromised detail, even on the latest medium format sensors.
  • Water White Pro Optical Glass | Extremely high 99.3% light transmittance and perfectly neutral colour.
  • Double-Sided Ultra Hard Hydrophobic nano-coatings | Easy to clean and difficult to scratch
  • Ultra-Slim Knurled Frame | These filters are thinner and lighter than their predecessors.
  • Cheaper than predecessors | The new UHC UV filters are 20% cheaper than the HUC Protector range.

While the aluminium frame of the Ultra Hard Coating (UHC) UV offers a benefits in both weight and pricing, we still stock a minimal amount of the HUC UV for those who insist on brass. Brass doesn't jam easily as it's a very malleable material and is more resistant to temperature changes. This means it won't get stuck as easily in extreme temperatures. The only drawback is the weight, brass is 3.5x times the density of aluminium, which means the HUC UV is heavier and a bit pricier.



About UV Filters

 

UV filters eliminate the ultraviolet light, which we cannot see, but affects our images. One of the first issues to take note of is that the light we as humans see and that is critical to our images' colour capture is around 400-750nm. Anything below is considered UV and anything higher is considered IR.

Most camera's sensors can potentially see a massive spectrum, ranging from 200nm to 900nm, which contains a lot of light that is detrimental to the colour integrity of any photo. For this reason, most cameras have an IR and UV filter that limit the range from around 250nm to 780nm. What remains between this range and the visible range can affect colour, but it is very seldom noticeable in images. It used to be a much bigger problem in the film days when UV filters were considered a must-have accessory. One can't absolutely make the argument that UV filters serve no optical purpose in the digital age, as there are situations in which they do help as they cut out the range between the built-in filter and the visible spectrum; 280-395nm. Their real purpose lies in something much simpler - as a protective element for the lenses that cost us so much money. 

In the film days, this was a secondary benefit to the filters, but with the advent of digital sensors and built-in UV filters, their secondary property has become their primary purpose. 

All NiSI circular filters ship with a hard plastic storage case. If you are purchasing multiple circular filters, the circular caddy pouch is a great addition for quick, safe and easy transport, storage and access.
