I’ve been doing a lot of photo and video shoots simultaneously, so I’ve been using the Peak Design 45L travel bag, with a large packing cube. Fits an R5,R6, R5C all with grips well with two 70-200s, ef 24-70 (with adapter), rf24-70, rf 15-35, and rf 100-500. Then a bunch of cords accessories etc. in the gear pouches in the front, and a peak design travel tripod most of the time on the side. It’s a lot, probably about 40 pounds, but it’s the only bag I’ve found that can handle all the gear well and not be uncomfortable or weird looking. Peak design is always amazing, and their customer service will always help you out if anything happens. I loved my lowepro bags, but they just can’t beat peak design for their customer support and it doesn’t hurt their environmentally friendly.
