Technical data

The difference between settings 8 and 4 is approximately
3 f-stops. Along with its zoom feature, it accepts a variety of
accessories including Barn Doors, Snoot, Grid and Filterholder
with 5°, 10° and 20° grids for a wide range of light shaping
possibilities. The Grid and Filterholder is the most versatile
accessory for the Standard Zoom Reflector.
Filters can be mounted between the light source and the
accessory. There is an air space between the filter and the
reflector which prevents the filter from being overheated.
Besides a Filter Cassette, there is a diffusion filter included.
It is a little known fact that grids are more efficient if a
diffusion filter is mounted behind the light source and the grid.
Light Control
Honeycomb grids narrow the light beam, and are available
in 20°, 10°, and 5° coverage. The four-sided Barn Door
mounts directly onto the Standard Zoom Reflector. It features
springs for mounting filters and/or honeycomb grids. It blocks
undesired light from striking the subject or the camera lens.
Mounted on the reflector, it can control stray light and add
additional control to the shadow areas. The Filterholder
mounts directly onto the Standard Zoom Reflector.
A gelatin filter or diffuser or 40x40cm (15.8x15.8”) diffuser
can be mounted. ASnoot, which is mounted into the Grid
and Filterholder and locked in place by the Filter Cassette,
provides concentrated light at a specific point.

but it doesn’t stop there. Highly specialized accessories like
the ProGlobe, ProBox, Hardbox and Profoto 5,7 and 8 foot
giant reflectors offer unique lighting solutions to any shooting
situation. Each tool offers a specific character of light
to create highlights and shadows in limitless combinations,
a broad palette that is easy to work with for the lighting
artist in you.
Unique Zoom Function
The versatile Standard Zoom Reflector is supplied with most
Profoto heads and is available separately. By pushing the
reflector forward or backward on the lamp head, the spread
and effect of the light can be greatly altered. Pushed back
(to setting 8), it gives very even lighting over a broad area.
The light-spread of 100 degrees, at a distance of 6.5'/2m
from a wall provides completely even illumination over an
area 13'/4m in diameter. At a setting of 7, the Standard
Zoom reflector offers a narrower beam that can evenly fill
an umbrella. At a setting of 4, the light is center weighted
with a gradual light fall off at the edges.
