Not very often, but once in a while I will snap a pic for a post I've done on TPF, like this one, showing how I typically carry my smaller prime lenses with two older-style Nikon rear lens caps, the ones with the interlocking ridges on the back end. With so many interlocking ridges, these caps basically fit together kinda' like Lego's do, and with a couple of wraps of tape, they are realllllly stuck together. This makes it possible to pull two lenses out of a fanny pack, camera bag slot, or out of a jacket pocket at one time. It makes it easy to carry the 70-300 + 24 on top, or 70-300 + 35 on top, or the 24+50mm pair, as shown.
