I got two of these bags from the 'Mystery Box' deal, and they're great. I'm not 100% sure I'll keep both, might re-gift one and get another color or size, but the 6L is fantastic. From measurements I thought I could get my camera/lens in sideways, but some reviews made it sound like the bag was tighter than they expected, so I wasn't sure. Turns out, it fits PERFECT. Also, I'm happy with the color. Since I didn't know what I would get, I took a risk, but the yellow looks really cool.
Oh, btw my camera/lens combo is a Canon EOS R6 mk 2 and the RF 100-500 L lens
