X lenses and lens profiles in LR4

Hello,

I currently own an X100, and am trying to decide between xe1 and xpro1.

With the X100 raw images, an application of the lens profile is necessary to correct some vignetting and distortion when the camera is used with and without the wide-angle adapter.

Is the correction necessary for interchangeable X lenses, like the 35 and 60?

If the correction is necessary, are the profiles available?

Thank you,

Dmitry.
