Canon EF Lens to Sony E-Mount
THANK YOU FOR CHOOSING VELLO
The Vello Accelerator AF
Lens Adapter is for attaching
full-frame Canon EF lenses
to Sony’s E-mount. It allows
a nearly full-frame field of
view on APS-C crop 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,
2
mounting a 50mm f/.4 lens
to an APS-C sensor will
usually give you a 75mm
angle of view. By adding the
Accelerator, you eectively
keep it close to the original
focal length of 50mm with a
stepped-down f-stop of f/.0.
This is a great advantage
for the widely-accepted
APS-C crop format.
The Vello Accelerator
aords additional benefits
by maintaining autofocus
and auto exposure with
AF-compatible Canon
lenses. It has four lens
elements in four groups
to maintain image quality.
And the detachable tripod
foot will work with most
brands of ball heads.
When using the Accelerator
on Sony full-frame
cameras, you must switch
to crop (APS-C) mode
for compatibility. Refer to
your camera’s user manual
for information on APS-C
mode. Some cameras will
do this switch automatically.
Note: The LAG-NEX-CEF
autofocus and auto exposure
will not work with the Sony
PXW-FS7 XDCAM camcorder.
