Note to owners of D40, D40x, D60, D3000 series, D5000 series bodies and the D7500: No conversion is needed to mount virtually any old lens on these bodies. Set your camera to M mode and make shutter speed and aperture settings manually.


Type A (limited) conversion: $25 per lens (so that old lenses can be used on most newer bodies. Note to Df owners: I have found that the meter coupling system on the Df is slightly different than other newer bodies. Please let me know if you have a Df when sending your lens(es).


Type B (full) conversion: $35 per lens (same as a Type A conversion but with additional work so that the lenses can also be mounted on the “Electronic Only” bodies such as the D90, D80, D70 and a few older ones.


Type C conversion: $35 per lens (installation of the traditional meter coupling yoke on AF or E styles so that these newer lenses can be used on old bodies with full aperture metering)


Upgrade from Type A to B is $10 per lens for my former customers but I recommend starting out with Type B
