This is a lens profile for the Meike 50mm f1.7 lens that I created using Adobe Lens Profile Creator 1.0.4.
To use it you will need to add LensTagger to Lightroom. Why? It’s a manual lens that transmits no metadata to the camera to identify it. You can’t edit metadata directly in Lightroom, and to apply a lens profile, Lightroom needs to locate the lens name in the metadata. The lens name should be applied with Lenstagger as “Meike 50mm f1.7”.

Once the lens profile is added to Lightroom and the metadata is updated, go to Lens Corrections panel, change Make to Sony and the Meike lens should be applied automatically.
