hey don't. It is an additional cost option, at least here in the U.S.

apologies for the misleading mini-rant, I removed that last point. Though the tap-in calibration puck remains an important Issue.

From what I recall Pentax in camera AF calibration does not work well with zoom lenses with wide FL ranges.

Truth is, it sort of sucks even with zooms having moderate range. I am hoping that the new APS-C will feature something like Nikon's automated AF adjust feature along with the ability to save focal-length-specific corrections.

On a related note, my question with this new lens compared to the non-Pentax Tamron version is, will it require firmware updates to camera bodies and DCU allowing them to recognize it and apply the proper lens corrections and profiles? If it does, I would expect to see firmware updates released very soon. I suppose for Lightroom, ACR, and other editing programs one could just manually apply one of the Tamron profiles, if needed, until they add the Pentax profiles, if they ever do.
