* Compatible FC focus gear required for manual focusing (can be used in conjunction with a compatible zoom gear).
* Until now, auto focus has been the only option available when using a
zoom gear. With the new Extension Ring 46 with Focus Knob, you can now
manually focus a compatible zoom lens. When your camera's AF frames do
not cover your subject, you can manually focus a compatible lens without
changing composition.
* This product is the ideal solution when you shoot fast-moving subjects
(which even the latest auto focus may not follow) or when you shoot in
dark environments and when there are lots of particles suspended in the
water; all situations where auto focus will not function correctly.
* The focus knob is located in an ideal position and angle to be easily operated with the index finger and thumb.
