DPRvived should add addtitional subforums for each lens mount - ie in the Nikon forum, adding an F-mount lens subforum and maybe a Z-mount one now or in the future - as many of the lens questions will crossover different camera bodies types and may not fall into ONE type - ie an F-mount FX lens can be used on a FX body as well as a DX one so what happens with the user has a both bodies and has a question about the lens? Do they create TWO post - one in the FX subforum and another in the DX one?
On the flip side, mounts that really don't have many users - ie Nikon's 1 mount - really don't need another subforum was those lenses are used exclusively for the 1 mount eco-system so they can be discussed in the 1 mount forum.
