Hi,
I think the naming convention usually used by exiftool is broken for the Pentax DA* 60-250 lens.
I think it currently is named "smc PENTAX DA* 60-250mm F4 [IF] SDM" but should be named "smc PENTAX-DA* 60-250mm F4 [IF] SDM".
This kicks it out of its place in the metadata lens list in Lightroom (now listed before the A-lenses).
Thanks. I'll fix this in the next release.
