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.
