As of now I'm carrying two camera bodies, 1 speed light, 1 50 1.2, and 1 24 1.4 a DJI Mini 3 and a few small pieces (memory cards etc)

Carry a wonderd 9L sling bag with an A7iv with a tamron 35-150, 24 1.4 gmaster and a second a7iii body as a backup. I carry 5 batteries, one godox flash and extra battery. One metal sd card case with backup cards. That’s all on me and accessible. In my car I have an “oh shit” small pelican case with another a7iii and a 24-70, and another flash backup. I shoot about 35-40 weddings a year.

My setup is 2 d850’s, 2 speed lights. 24-70, 35 1.4, 58 1.4, 24mm 2.8. Anything can break and it won’t leave a gap in what I can cover. I occasionally add a longer lens if it’s a church wedding and I need to be a bit more conspicuous. I also keep a d750, spare flash and 35mm f2 in my car as my ultimate everything went wrong backup. ie fell in a pond with my camera bag/got mugged.

One Rolleiflex, one Nikon F6 with a 35/1.4, one assistant to re-load the Rollei and manage rolls.

2 canon camera bodies, mounted with a 24-70 f/2.0 and a 105mm f/2.8 worn on a harness 90% of the day. In my case I keep a Godox flash, a 16mm lens for the dance floor, a 100mm macro lens for ring shots... & just for funzies, I carry around spare 50mm f/1.2 (which I almost never use but it's nice to have on hand)..... Spare batteries for everything, business cards, Advil 😉

Cardboard box pinhole camera.

Not a wedding photog, but my current event setup is Fuji x100 with the 35mm and a canon r6 with the 85mm. I have a wide, I have a tight, I can zoom with my feet, both cams are good in low light, Fuji has flash, I’m never messing with gear, I’m super comfortable on both cams and I can concentrate on connecting with people and finding my moments.
