Nikon High Performance Genuine Lens Protection Filter ARCREST PROTECTION FILTER 77 mm AR - PF77 Alcest Protection Filter
Ultra low reflection AR coating and high optical performance realize high performance protection filter to the utmost limit to the lens's original drawing power Adopt ultra low reflection AR coat "zero one AR coat" pursuing about 0.1% single side reflectance Nikon original The mounting technology to the development frame "Flat Plane System" greatly reduces the load on the glass Reduces the high image quality as compared with the case of shooting without a filter
Adopt high-quality optical glass that is also used for NIKKOR lens Adoption of water-repellent / oil-repellent coat which is hard to stain dirt such as water droplets, oil, fingerprints, etc. and can be wiped easily even if it adheres Not formerly unprecedented Flat accuracy Prevents vignetting even with wide angle lenses Thin frame design Suppresses ghost and flare during backlighting Made in Japan
Adopt ultra-low reflective AR coat "zero one AR coat" pursuing about 0.1% single sided reflectance High performance protective filter realizing high optical performance to minimize the influence on images while protecting important lenses . To polish high quality optical glass with high precision and maintain its flatness, mount it on a filter frame with Nikon's unique mounting technology "flat plane system". Ultra low reflection AR coat "zero one AR coat" adopting ultra low reflection AR coat which suppresses occurrence of factors which adversely affect optical performance to the utmost limit, reflectance variation is small in the whole visible light range, and single sided reflectance approaches about 0.1%. Reducing the color balance disturbance to the minimum, reducing the occurrence of ghosts and flares leading to degradation of the drawing performance, high image quality comparable to that obtained when photographing without a filter is obtained.
Even in harsh shooting environments it is difficult for dirt to stick to it, even if it is attached, it can be wiped off with ease, with a water repellent / oil repellent coat with shooting with a super high pixel camera with little influence on image quality, various shooting scenes It is characterized by being able to use with confidence at.
High quality optical glass diagram adopted also for NIKKOR to realize excellent transparency and homogeneity) Comparison of planar accuracy by original tool
With the newly developed high precision polishing technology, we achieved extremely high planar accuracy with less than 1 interference fringe. The highly accurate flatness of the glass surface suppresses the wavefront disturbance of the incident light to the utmost limit and does not impair the original descriptive power of the lens.
When air enters between the filter glass and the prototype, interference fringes are generated. Uneven disturbance occurs in the interference fringe as the planar accuracy is low (surface distortion is large), but ARCREST is a stripe Almost no occurrence or disturbance is seen.
Material, polishing technology, mounting technology, high optical performance achieved by sticking to everything
Comparison of resolution (enlargement within red frame)
ARCREST can describe the detail part of landscape photography with high resolving power close to the original imaging force
Comparison of ghosts (enlarging the inside of the red frame)
The nightscape cityscape with a strong light source, due to the effect of zero one AR coat, ghost is suppressed in ARCREST.
Adopted excellent water and oil repellent coat We adopt our own water and oil repellent coat developed for the filter. Dirt, such as water droplets, oil, and fingerprints are less likely to stick, and even if it adheres, it can be easily wiped off, demonstrating high antifouling performance. It also has high durability that passed the wiping test * of 1000 times or more with a test load of 200 g. Water repellent and oil repellent coat is applied to both sides of the glass, so you can concentrate on shooting with peace of mind even in harsh shooting environments.
* According to ARCREST test conditions. It is different from the test condition of fluorine coating of NIKKOR lens.
