I am looking for a medium sized sling bag...something that ideally can hold my 70D with the 70-300L on it, and/or the 17-55 and then have space to store the other lens and a 430 EX II. I have a couple of backpacks but they don't play so nice with the Cinch, and I would like something in between the huge fastpack 350 and the very small 100..
Any suggestions?
