My Kata LighTri 312 DL sling bag arrived today. While I was able to fit my T3i (with attached 18-55) and a 55-250, I can't figure out how to adjust the straps to make this bag fit well.
Also, the bag came with a rain cover. Despite my efforts in folding this rain cover as tightly as possible, it takes up valuable space inside the bag. Is there a special hidden compartment or or method to hiding the rain cover?
I checked You Tube and Google, but there is little, if any, info on how to wear/use this bag.
p.s. Looks like it is designed to fit only on my left shoulder. Is there a way to adjust it to fit on my right shoulder for when I get tired of carrying it on my left shoulder all day?
