Yesterday, I bought this very beautiful Olympus F.Zuiko Auto-S 50mm f/1.8 that I randomly saw in a shop. I know this was special and wanted to take the challenge of converting it for use on Nikon DSLRs. 




So today, I did...

OM mount only has a difference of 0.50mm from Nikon's (see Flange Distance), so working this out shouldn't be much challenge. Aside from flange distance being a factor, the simple design of OM lenses makes it the easiest lens to convert for Nikon.

The first step was to clean the fungus inside, there was only a thin hairline of fungus to clean.

The next step was to remove the mount and also to disassemble the other parts for cleaning.

After cleaning and restoration, they look squeaky clean and like new now!

There's a little lever that keeps the aperture from closing. This lever is dependent on the mount that I just removed. Without the original mount, there's nothing to manipulate the aperture blades to close and open.

So my solution... I got one of those broken springs that I've been keeping for emergencies like this. That spring was used to keep that lever pulled. I tested the aperture ring to see if the blades would close without problem. Once the connection was stable, I added a drop of super glue to permanently fix the lever in place.

With some spare Nikon mount on hand, I just drilled holes so that it could be securely patched to the mount of the lens. We're not done yet!

Last step... the group of glass at the rear was adjusted and then I made some test shots at f/1.8 to see whether it focuses accurately when at infinity (∞).

There are some gaps at the side, where the original mount's DOF preview buttons used to be. We need to patch that up to prevent light leaks. There... we're done!

First impressions... it's a tiny pancake lens. I learned that there's a 3-digit alphanumeric code right under the focus ring rubber grip. It says 'A93'. Meaning, it was made in factory A at around 1979, March. According to my research, this code means that it was made before 1983, which lenses began to be treated with multicoating.

The images look truly beautiful at f/1.8, there's a special pearly look to it. Colors are neutral and very natural on digital cameras. It's not a razor sharp lens, not one I would use for product shots, macros and little details. But the bit of softness in contrast is what gives its special personality. It sweet spot is at f/11, where it is sharpest.

All of my sample images below are unedited. See for yourself the quality of this lens.

As a Nikon camera owner, I really love the quality glass of Nikkor lenses. But of course, I do love the challenge of having to convert and try lenses other than the Nikkor ones. Which is why this OM lens felt very special on first look. This is my first Olympus lens, hopefully not the last!

Tomorrow, the 25th, I must go out to make some lens porn...
