I currently use Canon EOS RP bodies with Canon EF 16-35mm f/4L IS USM (07/2019), RF 24-240mm f/4-6.3 IS USM, RF 35mm f/1.8 Macro IS STM, RF 50mm f/1.8 STM, RF 85mm f/2 IS Macro STM and RF 600mm f/11 IS STM lenses.
In the past, I have used Canon EOS 1D Mark III, 5D Mark III, 5D Mark II, 5D, 7D Mark II, 7D, 80D, 70D, 60D, 50D, 30D, SL1, M3 and M bodies, and too many Canon and third party lenses to mention. The gear list part of my profile on DPReview is usually up to date. You can check it out here.
I [rarely] use 430EX II, 270EX II and 90EX Canon Speedlites with various light modifiers.
I currently am using Black Rapid Double Breathe and Cross Shot camera slings that attach to the cameras' tripod mounts.
I use Bogen 3021 tripod legs w/Manfrotto Midi Ball Head (488RC0) and a Manfrotto 290 Aluminum Monopod.
My primary storage bag is a Think Tank Photo Airport Commuter backpack which has been de-backpacked by cutting off those straps. I use several smaller Think Tank and Lowepro bags and holsters for various situations.
I process my RAW images on a 13 inch MacBook Air (2015) with Canon's Digital Photo Professional, Apple's Photos app and/or HDRSoft's Photomatix Pro.
