Thank you for choosing a Vello Lens Adapter. This model allows you to
mount older Canon FD lenses onto Canon EOS bodies. This is a mount
adapter and an optical adapter. It acts as a short teleconverter, increasing
focal length by a factor of 1.25 and reducing the lens aperture by
approximately one f/stop. Auto Focus will be unavailable when pairing auto
focus cameras with older manual focus lenses. Vello Lens Adapters are
manufactured to t securely to the lens but not so tightly that they are
difcult to remove. Please follow the instructions below to mount and
remove your Vello Lens Adapter.
Although the lens will t physically, automatic diaphragm (AE metering), and other functions
dependent on communication between the camera body and lens, will be disrupted by a lens
adapter. You will need to set exposures manually or meter in aperture priority (stop-down)
mode. If the lens does not have a manual aperture collar, the aperture will be stopped to its
smallest f/stop. Focusing to innity is retained.
