I use a Lowepro Messenger 100 for when I want to carry a few more stuff, but I feel sometimes it does not fit enough stuff.
I can fit in it the Fuji X-E2 with maybe the 35mm mounted, on the side I can fit the 60mm or the XC 50-230mm and in the front pouch, with the extra batteries and a few more things I can fit in also the 27mm.
I've also been able to fit the X-E2, 60mm, 27mm, 35mm and the XC 50-230 but, without the lens hoods monted on any of them. You can also put the X-E2 with the 18-55 and the 60 and 35 for example.
It has 2 main compartments, and sometimes when carrying more lens I'd think the 150 would leave more space to put all of them.
I should take some photos to show the configurations, but I don't have that now, sorry.
When I want to shoot street and want to take just the camera with one lens, I use the Black Rapid Snapr 35. It fits the X-E2 with either the 27mm or the 35mm, without the hood. And a couple of batteries on one side and a small joby tripod micro 250 on the other side.
I'll take photos later to share.
