Hey guys, First post here but have read countless posts here! Now I need some specific help. I used to shoot with an E-PL2 but recently picked up a OMD E-M5 and loving it. The compact body of the E-PL2 and the Pany 20mm f1.7 I had was a great setup for travel, but now I am looking to get the Oly 12-40mm for the E-M5. This setup makes it a bit bigger so it won't fit in my old Timbuk2 messenger bag (which I adore but must get something else). I travel quite a bit for work (I'm an airport regular) plus I do one or two international trips across the world a year (for vacation). So here are my needs: 1) Must fit a 13" Macbook Air 2) Must fit the E-M5 with the Oly 12-40mm lens 3) Must have pockets big enough to fit passport and other travel docs 4) Must have a pocket for a water bottle (or interior space big enough to slide one in) 5) Must have some additional luggage space for other things (books, magazines, etc) but cannot be too big 6) Must be somewhat weather proof 7) Must be a messenger bag 8) Under $150 would be ideal Niceties: 1) Handle on top 2) Loop around the back to slip through carry-on luggage 3) Doesn't look like a regular old camera bag The one that has caught my attention so far is the Tenba Messenger bag. Not sure if I'd get the Mini or Small, but it has many of the features I'm looking for. http://www.tenba.com/products/Messenger-Photo-Laptop-Bag-Small-Black.aspx#Overview Do you guys have any other recommendations? Thanks for the help in advance!
