A photo I posted to TPF in april of 2013, in which I detailed the way I use a three-lens 24/35/50 Nikkor lens kit, with two rear lenscaps taped back-to-back, so that two lenses will easily fit into one compartment in a bag, fanny pack, or easily fit in a jacket pocket. Older style Nikon lens caps have interlocking ridges that makes this tape connection super-secure and strong!
