When I'm traveling (touristing), I'm usually using the E-M5 mk I and the Oly 14-150. I've been using various shoulder bags (worn cross-body), but have been thinking about a waist bag. Any recommendations? Ease of access and minimizing bulk are considerations. I was looking at the Think Tank Digital Holster 5, but it's so hard to judge things without seeing them in person. (The Hubba Hubba Hiney -- seriously, who came up with that name? -- looks too bulky for what I want.) For part of my next planned trip, I may be carrying the Pana 100-300 as well. I was thinking about an add-on lens bag for that.
