So I recently bought a used Nikon D100 with a Nikon AF Nikkor 28-105mm. I am in the process of selling my dad's Nikons N80 and N6006. One has a Tamron AF 28-200mm lens, the other has a Nikon Nikkor AF 35-70mm lens. These are both fairly old cameras (hence they are film), so the lenses are older too. Would you suggest that I switch out my 28-105mm that I recently bought for the Tamron 28-200mm and then sell the 28-105mm with the film cameras? I am nervous that although it has better range, it may not be as up-to-date at the one I already have. Also, would you recommend that I sell the lenses separate from the cameras? I would normally sell them together if they were digital cameras, but I am afraid that more people may want to by lenses than 35mm film cameras. Any help would be greatly appreciated!
