pro master HGX PRIME User manual

Congratulations on your purchase of a ProMaster HGX Prime Variable Neutral Density Filter. It is a useful tool
and a precision instrument for both still photography and videography. It allows you to reduce the amount
of light entering your camera’s lens with a range of 1.3 to 8 f-stops. For still photography this can be helpful
for creating longer shutter speeds to create a special eect such as blurring the motion of running water.
For videography, it is a great aid which allows you to use a large lens aperture (thereby achieving your
desired depth-of-eld) in bright lighting conditions. Please read through all of these instructions so you can
condently employ this VND lter in your creative process.
BASIC OPERATION
1) Attach the lter to the front of your lens using its lter threads.
2) Rotate the VND lter to its Min point.
3) Slowly rotating the lter away from its Min point and towards its Max point increases the lter’s neutral
density factor and decreases the amount of light passing through your lens.
4) The lter will stop at the Max point to avoid going beyond its useable limit.
We recommend composing and focusing your lens with the lter at its Min point because it can be more dicult
to see, compose, and focus with increased density. Consider setting your lens/camera to manual focus so it will
not try to autofocus once the lter is set to a higher density.
ADDITIONAL OPERATIONAL NOTES
“X” Pattern:
All variable neutral density lters have certain limitations due to the laws of physics. Cross Polarization, also
known as the “dreaded X”, can occur when higher densities are used in combination with a wide-angle lens.
This eect begins as a darkening at the edges of the image; and, it can manifest itself as the appearance of a
letter X over the image at the highest density setting. To aid your use of this lter a white letter“X” has been
inscribed on the outer ring showing point where cross polarization begins with most wide-angle lenses.
With almost every lens you will not see any image degradation when the lter is set between the Min point
and the X point. Once you move the lter beyond the X point towards the Max point you might see some
image degradation due to cross polarization. Whether or not you see this aect will be unique to the lens
you are using. Therefore, the white X is a guide.
Note: Cross polarization does not generally appear
when using a normal or telephoto length lens. And
not all wide angles may experience the same aect.
Each lens and camera combination presents a
unique situation. Use the X mark as general guide
while paying close attention to the image in your
viewnder.
DENSITY MARKS
You will notice a series of white lines along the lter’s rim. There are 8 in total, including those at the Min and
Max points. Each of these lines represents a specic density of the lter. They go like this:
| | | |…. |…|.. |. |
1.3 stops 2 3 4.. 5.. 6.7 8 stops
USING THE TACTILE CONTROL KNOB
Your lter comes with a small, knurled knob attached to its outer
rim. This control knob provides a tactile experience when rotating
the lter through its density range. It allows you to feel the lter
and rotate it while keeping your eye on your subject through
the viewnder. You can also use the knob to change the lter’s
density, and therefore the exposure, while capturing video to
create a special eect. Finally, this tactful knob can be unscrewed
and removed if you prefer.
