Please don't hesitate to ask me any doubt regarding this conversion.
|This is the Olympus OM-System Zuiko 21/3.5 lens.|
|It has three screws at the bayonet base, let's remove them.|
|And just lift the mount.|
|Now make a spring like this one from a piece of 3.50mm|
|We have to unscrew this screw just the necessary to pass the spring under it.|
|This way, here I've used a tweezers and the plastic tool.|
|Now, with the hook, pass the other side around this aperture lever.
Again, the plastic tool was useful to keep the aperture lever on position.
|Ready, it is important to check if the iris close until the smaller position, if not, it means the spring too long.
It is a good idea to drop a small quantity of nail varnish on that screw, so it will not get loose. Please let the varnish dry completely before mounting the lens on the camera: the smell must disappear.
|I've painted the white metal screws with my flat black marker from Micro-tools.|
|All the screws are black now.|
|Now install the Leitax mount using the provided screws, the orange line goes in front the scale center.|
|And you can use this Zuiko lens on any Nikon F-mount or Pentax camera.|
