Olympus Zuiko 80mm f/ 4 Auto Macro. Adaptation on any DSLR Camera




Olympus Zuiko 80 mm f / 4 Auto Macro - a good macro lens, macro shooting is apply to a reproduction ratio of 1: 1 or more. See also Olympus Zuiko 80mm f/ 4 Auto Macro review and samples. The lens is specifically designed for use with a special telescopic auto extension tube and constructively has a long rear ledge, like in old rangefinder lenses. But in spite of such a constructive the lens has a long flange distance. About 65 mm. With such long it can be mounted on any camera with infinity safe, and even with a minimum "surgery." I will describe below how to adapt.  

 

Finalizing aperture control

The lens has an automatic aperture control, which works with cameras Olympus OM only and with telescopic auto extension tube. On any other system, it will not work, so it must be removed, but leave the manual control. Open the aperture so that it stood on the value f/ of "4". Remove the tail and pull ring. Next, remove the ring with extra details that provide automatic aperture control mechanical connection with a camera, they fixed screws. Now the ring should look like this.

Next, insert the other end into place, and check how the diaphragm. To adhere to this ring by hand and cover the aperture manually. If everything is inserted correctly, it will close properly and comply with the values on the barrel. Olympus Zuiko 80mm f/ 4 Auto Macro Adaptation

Now take glue, once again pull ring and smear with glue. Put back into the correct position. Keep a few seconds. Now the ring is fixed, and we can control the aperture manually. Also when pulling the extra parts pressing buttons fail automatic aperture control. Glue them to the frame to maintain the aesthetic appearance. Reassembling lens all back.

 

Mounting the lens to the camera to the correct flange distance

To install the lens on Nikon F camera I used two sets of Chinese extension rings, which buy on Ebay. One for Nikon, and the other for Olympus OM. They are absolutely identical and differ only in the bayonet mounts.

Match the desired configuration for the required length. I get that. Now, on one end of the cheat Nikon mount and on the other - Olympus OM. Olympus Zuiko 80mm f/ 4 Auto Macro Adaptation

The result is such an adapter. Mount with it’s help the lens on your camera. Now we can use the lens to the fullest. By varying the number of rings, we select the desired length of the focus to infinity to the closest distance. Olympus Zuiko 80mm f/ 4 Auto Macro Adaptation

If we need to shoot close-up, just enough wind the additional ring, we now have two sets of them, and we can provide the scale greater than 1: 1. But is also the use of a minor inconvenience - if you want to go from infinity to close range, you need to remove the lens and cheat additional rings, but overall it's not such a problem.
