This week, I have been carrying: 70-200 f4IS, 85L, 40D (no grip) with 24-105mm attached, 77mm 500D in case, a set of kenko extension tubes, Panasonci LZ8, and msc small items..... All of this in my Boda bag!
I say this because I was ready to buy the Flipside 300 but at the last minute I saw the Boda and tried it. I am amazed at what will fit in the boda.
