NEW 77mm Hoya PRO-1 Digital DMC (Digital Multicoated) ND4 Filter
Neutral Density (ND) filters help reduce the amount of light entering the lens, but have no affect on color balance. The main uses are:
1. To enable slower shutter speeds so as to emphasize movement, such as waterfalls, clouds, the sea, automobiles, etc.
2. To enable wider aperatures to be used so as to decrease the depth of field, which is very desirable in protraiture or macro work.
The ND 4 filter has a filter factor of 2-stops, so you are able to slow down the shutter speed or increase the aperature by 2-stops.
Pro1 Digital Filter Series are filters designed exclusively for Digital Cameras. The Pro1 Digital filter series is the top of the line filter for digital cameras. The Hoya Pro1 Digital filter series key features:
- Digital Multi Coated (DMC) - These filters greatly reduce lens flare and ghosting caused by reflections
- Black Almite Frame (BAF) - A black matte aluminum satin finish almite frame for reducing reflections
- Black Rimmed Glass (BRG) - Black rimmed glass reduces light reflection around the filter edge
- Low Profile Frame (LPF) - Ultra thin filter frames to help avoid vignetting on super wide angle lenses
- Knurling Edge Frame (KEF) - Equipped with a knurling edge for easy attachment and removal
- UV Protected Case (UVC) - Filter cases are UV protected to further lengthen the life of filters
Digital Cameras need Multicoated filters.
Digital camera CCD or CMOS sensors are hightly susceptible to reflections - this stray light can ruin your photographs! Don't risk your valuable photos by using bare-glass filters.
The Clear Advantage.
Take a bare glass filter, hold it so that light reflection off the surface can be seen. Then take a long, very thin object like a pin or the tip of a pen and hold it over the filter so that its reflection can be seen. There will actually be two reflections of the pin on the surface, one a little more pronounced than the other. The more pronounced reflection is from the front surface and the lighter one is from light reflecting off the rear surface. Now try it with a HOYA Digital Multi-Coated filter and see how much more dim the reflection is, a dimmer reflection means less light is reflected off the surface of the glass.
