Thanks for the replies. I was curious about the sling bags I had already looked at a few online. Here is what I typically carry; 1 OMD body, 60mm macro, 7-14 zoom,12-60 zoom, 40-150 or 80-200 zoom The 12-60 is my walk-around lens so it is always on the body. I use the 80-200 the least and I don't carry it unless I'm planning on shooting wildlife or sports, otherwise the 40-150 (much smaller and lighter) is with me.
The 80-200 (2.8) is a big chunk of glass and won't fit in most bags while attached to the body and doesn't fit into most bag lens partitions. For most sling bags I would have to it keep in a soft case and stuff into the top compartment. For the other lenses, when I arrange all the pieces together, I doubt I could get everything comfortably into the Amazon bag. it would certainly exclude the 80-200. I also looked at several of Lowepro's sling bags liked them until I saw the Minspring The Mindshift looks the most promising. I like that it is a dedicated camera bag and not a multipurpose bag. It has a full length flap so everything is accessible. I could possibly get the body with big zoom (10" OA)in that bag. I don't care for having to stack lenses but that isn't a deal breaker. There is a competing bag made by Turnstyle I'm going to look at also.
