\n How to make an Olympus Pen F\/FT\/FV to Nikon lens adapter\n
\n\n by Anonymous\n <\/p>\n

\n \n <\/p>\n

Having an Olympus Pen F\/FT\/FV camera is fun, but there are a limited \n number of lenses that were made and the availability of quality used lenses \n is not very high. My other 35mm SLR is a Nikon and I have quite a few \n lenses for it. I tried to find an Olympus factory Pen to Nikon lens adapter, \n but if you can find one the cost is very high. So I resigned myself to \n using the more readily available T-mount adapters that were made for the \n Pen F series (Vivitar, Accura and Tamron were some of the after market \n manufacturers of these adapters).<\/p>\n

I ordered an adapter from an internet camera shop that specializes in \n used and classic camera equipment. The cost was quite reasonable. The \n draw back with a T-mount adapter is that the mount is essentially dedicated \n to one lens. When I received the adapter, I noticed that the mount was \n quite large. So I looked into modifying it to fit my Nikon lenses. A Nikon \n BR3 lens-reversing mount would work well as a lens mount for the Nikon \n lenses and there appeared to be plenty of room to slide the BR3 over the \n T-mount barrel (after the serrated edge was removed).<\/p>\n

\n \n <\/p>\n

The Nikon film plane to lens flange distance is 46.50mm. The Olympus \n Pen F cameras have a film plane to lens flange distance of 28.95mm. This \n means that the adapter will have to have an Olympus flange to Nikon flange \n distance of 17.55mm ( Nikon lens-flange distance of 46.50mm – Olympus \n Pen F\/FT\/FV lens-flange distance of 28.95mm = 17.50mm adapter flange-to-flange \n distance).<\/p>\n

\n \n <\/p>\n

The height of the T-mount adapter is 26.00mm from flange face to top \n of the serrations and the lens-mounting bracket on the Nikon BR3 is 3.65mm \n thick (this is the lens mount and lens release tab held onto the BR3 barrel \n by four screws). So the T-mount adapter will need to be shortened by 12.10mm \n (present height of 26.00mm – final height of 17.55 + Nikon BR3 mounting \n plate of 3.65mm = 12.10mm).<\/p>\n

The outer diameter of the T-mount adapter is 49.96mm and the inner diameter \n of the Nikon BR3 is 49.48mm. So I enlarged the Nikon BR3 inner diameter \n by 0.48mm (49.96mm – 49.48m = 0.48mm). Also, the T-mount adapter release \n button area needs to be opened up on the Nikon BR3. This is what you end \n up with after machining the T-mount adapter, the cut off serrations and \n the remaining serrations turned down to the diameter of the T-mount barrel, \n and the machined BR3 with the notch for the T-mount adapter release button \n and the 3 set screws to hold the pieces together.<\/p>\n

The last step was to fit the pieces together and make sure that the Nikon \n lenses would focus at infinity. A little light filing was required in \n order to get an exact final flange-to-flange distance of 17.55mm. The \n finished adapter works very well and does focus to infinity. Total time \n was about 3 hours.<\/p>\n

This modification to a T-mount adapter could be done for the following \n camera lens mounts:<\/p>\n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n
