At one point when shooting Nikon I had the 24-70 2.8, a Sigma Art 35 1.4, Nikon 50 1.8G, 85 1.8G, a Sigma 150mm OS macro [had the Nikon 105 just before this] and the Nikon 300mm F4 - I had the 70-200 2.8 VR with a 1.7x TC also but sold those to buy the 300 F4 [and 35mm I think] - used to cart most of that around on my bike just going out for some casual photos
Man did I learn when my back gave in [not from carrying all of that, but a work accident] - Now it's compact and simplistic and i take more photos, enjoy it more too. Others seem to be able to manage their mounds of gear better than I could, I hated leaving anything behind. And it was affecting my photography, I'd get frustrated missing shots while changing lenses. Just how I prefer it now, rather have a couple decent lenses than a bag full of so-so ones that would just wreck my head ... and back!
When i had all of that some people thought I was a 'pro' and i was getting asked to do weddings, which I did because I felt I should probably make use of it all and get something back - but I detested doing photography as a 'job' on side, takes the fun out of it for me. I see it as more a therapy
