To the best of my interpretation is is not a roadmap lens but a lens roadmap. This probably refers to a line of lenses usually aimed at a single lens mount such as Nikon or Canon lenses for their R or RP cameras. I suppose that it is a listing of lenses that fit a particular camera. But you are right I think. Another “fancy” word for something that did not need a “new” word. cheerio, Andy > On Dec 27, 2019, at 7:50 PM, PhotoRoy <photoroy6@xxxxxxx> wrote: > > What is a roadmap lens?
