I pulled an old Nikon lens brochure from 1985 and counted 78 lenses, and a latest Nikon lens brochure and counted a whopping 88 lenses; counting each TC as a lens, and including still-in-production MF. So there are 8 overlapping lenses between 1985 and 2017. And yes Dave you have a point here - you have to pare down when you own the entire current production lenses, or some combination of old and new.
Gee, how many do I have? My last count was 66 and I definitely added at least 2 more!
Dave I need to know why 44? Why not 66? Or 68? Then I don't have to pare down!
But if you do count the latest Nikon lens lineup, there is an insane 16 normal zooms! The 18-xxx alone 8 models (including the 17-55 and the latest 18-300). There are five (5) 24-xx zooms, and two 16-xx zooms.
Makes you wonder why Nikon cannot devote time to update some lenses... O they are updating the 18-xxx zoom!
