Are there any Ona Prince or Berlin Owners here? I use mainly inserts in my messengers bag but they often do not carry enough. I am wondering if the following would be fit in these bags: E-M5 ii, O12-40 (both mounted and unmounted), 2 - 3 of: O12, O17, O25 & O45. iPad Air. Sunglasses cases, etc. The problem that I have my current system is that if have more than one prime with me I too often have to rearrange the dividers when I mount or unmount the 12-40. I think that it is time to go back to a dedicated camera bag. I do have a Timbuk2 Snoop that works but I prefer the size and looks of the Ona bags.
