My ongoing search for a nice little u4/3 pack continues.. I know there are plenty of shoulder bags that would do the job, but unfortunately I have a few muscular issues in the neck and shoulder so I'd rather not have a strap hanging off either shoulder, which is where the bum bags come into it. The Lowepro Inverse bags look good, but which one is preferable? The 100 or 200? What I have to put in there: - E-P3 - 9-18, 20, 14-42, 40-150 (all u4/3) - Couple of memory cards, filters, adapter gins, hoods, and batteries My only issue with the Inverse bags (I've yet to see one in person), is that they look quite bulky for a bum bag? Can you have the bag on the side (hip) most of the time, rather than on the front or back? The other alternative I've seen is the Think Tank Pro Belt with the Hubba Hubba Hiney (great name!) or Speed Changer. It's a little more pricey but obviously has more flexibility down the track.. All thoughts appreciated!
