LENS MOD: Replacing The OM Mount for a Nikon Mount, Olympus Zuiko 75-150/4

I'm using a Nikon D5200, which uses the Nikon F mount with its flange distance of 46.50mm. It is the longest flange distance of any existing digital SLRs today, so adapting lenses from other mounts, which have shorter flange distance, makes those lenses 'short-sighted'.

In simple words, they cannot focus to infinity.

The easy solution is to use an adapter with correctional optical glass. However, this glass makes the maximum aperture of the lens 1 stop darker. When you set to f/2, the light is more like f/2.8. Set to f/2.8, it becomes more like f/4, and so on.

That's why I always make an effort to modify the mount of the non-Nikon mount lenses that I could get my hands on.

Fortunately, it's an easier case with Olympus lenses, the old ones that use OM mount. There are mount replacement parts that can be bought from abroad (not adapters!). You simply swap the original OM mount of the lens for this OM-Nikon mount replacement. 


Notes:

1) This adapter is for OEM Olympus lenses only, not the third party lenses.

2) This is not compatible with some Olympus lenses. I originally bought this for the Olympus 65-200/4 but not compatible. Fortunately, I could use it on my Olympus 75-150/4, which I'm going to demonstrate here.
