Nikon F-Mount to Micro Four Thirds

2
The Vello
Accelerator Lens
Adapter is for
attaching Nikon
F-Mount lenses to
Micro Four Thirds
cameras. It allows a
wider field of view
on Micro Four Thirds
sensor cameras by
magnifying the angle
of view by 0.7×.
This also provides
an extra stop of light
without decreasing
image quality. For
example, mounting
a 50mm f/.4 lens
to a Micro Four
Thirds sensor will
usually give you a
00mm angle of
view. By adding the
Accelerator, you
eectively produce a
focal length of 7mm
with a stepped-down
f-stop of f/.0. This
is a great advantage
for the widely
accepted Micro Four
Thirds format.
The Vello
Accelerator aords

half-stop increments.
It has five elements
in four groups to
maintain image
quality. And the
detachable tripod
foot will work with
most /4-20 mounts
as well as Arca-type
head assemblies.
Note: Although the
lens will fit physically,
there is no electronic
communication
between the adapter,
lens, or the camera.
Automatic diaphragm
(AE metering) and
some other functions
will be disrupted
by the adapter.
