Q
FD series adapter ring installation and operation steps.
A

There are two types of FD mounts
FD/FL Breech-Mount (with a silver ring, you need to rotate the silver ring when attachment and removal), breech-lock mounts are identified by the silver ring
New-FD Bayonet Mount, bayonet mounts are identified by a red dot next to the lens release button

Here are the steps to install breech-mount version

  1. Set your lens to smallest except for auto(bayonet mount only)
  2. Rotating the Lock-Open ring of the adapter on the OPEN side
  3. Line up the red dot with your lens and adapter ring(if yours is bayonet mount, just turn the adapter ring towards clockwise direction to make lens and adapter tight,then ignore the 4th step)
  4. Turn your lens ring towards counterclockwise direction to make the adapter ring tight with your lens
  5. Rotating the Lock-Open ring of the adapter on the LOCK side to engage the aperture closing pin

Operating the adapter

  1. If you'd like to operate the lens aperture with the adapter; on your lens, set the aperture to the smallest opening and use the adapter ring
  2. If you'd like to operate the lens aperture with the lens; place the adapter ring on the small aperture(Lock place) and control the aperture on the lens

 
Q
Pentax pk mount usually means pentax k mount which has a flange distance greater than m. is this adapter for adapting leica m lens to pentax q camera?
A
I actually have not received this adapter yet. It's shipping from China. Don't think that was disclosed in the ad. However, I do not believe this is for the Pentax Q body rather for digital and film cameras that take the Pentax K mount in its many variations. So I'm expecting to be able to mount my Leica M mount lenses on my digital and film Pentax K mount cameras, no autofocus or relay of exposure information, only to be used with manual focus and exposure. 
Q
Am I supposed to use an adapter to attach to a Nikon camera? If so, can you suggest an adapter?
A
No the other way this is to be able to mount the Nikon lenses onto the micro 4/3 camera body
