Eric, my need for a true catalog is not very strong. Between my Mac search capabilities and PM I have had very few problems managing and accessing my images, but I am also use keywords extensively. I do want to be sure I understand your answer on edited Lightroom images. One of the nice features of PM/NX2 is that NX2 generates a "edited" preview image that I can extract in PM and I frequently use these jpgs for email, etc. My understanding is that in Lightroom, as in NX2, the edited view is based on side car files. Are you saying that the behavior of nef files edited in Lightroom and viewed in PM is the same as with NX2?
