There are some excellent Nikon lenses that lack the aperture ring to operate the diaphragm. A normal adapter will not help us to use this lens properly on a Canon camera. |
|
Our Nikon-Canon mount for Nikkor-G lenses includes a special lever to overcome this limitation. | |
The Nikon lenses have at least three equidistant screws, those are the ones we are going to use. |
|
![]() |
Take the one in front the lens scale center as a reference, the other two form a equilateral triangle with it. |
First, check the screw length. This lens uses the 5.5mm long screws |
|
The one used for the Leitax mount has to be about 2mm longer. |
|
We have to remove the three screws that form an equilateral triangle from the Nikon mount. | |
![]() |
and save them in the provided small bag. |
![]() |
Now place the Leitax intermediate ring on top of the Nikon bayonet.... |
The sculpted recess of the ring goes near the aperture lever of the lens. | |
There is no need to remove the weatherproofing rubber ring of the G lenses, just help the Leitax ring to fit inside it with our plastic tool. | |
![]() |
The plastic tool is also handy to adjust the ring position until the holes coincide. |
![]() | Now we can use the three provided screws to securely attach the ring to the Nikkor lens. |
![]() | And we are ready to put our special lever in its place, just on the left side of the lens lever. |
![]() | Now put the Leitax mount on top of our ring. |
![]() | The position is easily determined for the bayonet lock slot, it has to be near the opposite side of the G-lever. |
![]() | Now attach the bayonet to the ring with the provided small screws. |
![]() | Our Leitax mount covers the Nikon bayonet with a flat black painted rim. This avoids flares in our pictures. |
![]() | Now the Nikon-G lenses will be as solid as a Canon lens on a Canon camera. |
![]() | Another view. |
![]() | It is very convenient to operate the iris with one hand and the zoom and focus rings of the lens with the other. |
