Not only does online dating allow you meet people from anywhere in the world, but you can do it at your leisure, which is perfect for people who are always on the go or have busy schedules that make it difficult to go out and meet people the traditional way.

If the register of the lens system is SMALLER, or EQUAL (less than 1mm difference) than the camera system, the adaptor requires an optical element to make infinity focussing possible.

Otherwise such an adaptor would act as a macro tube, putting the lens further away from the body than designed!

Also, the above non-optics formula only works if the lensmount is a bit smaller than the camera mount.

Other options/differences are in the shape of the 'drain-channels' of the tap, for normal holes straight channels are fine, for blind holes you need spiral channels, to get the metal shavings out. However, even custom order adaptors have to obey an optical law: the register of the lens system should be LARGER than the camera system.
