Second body for kit?

With X-E cameras being my main gear, I'll be slightly biased, but I agree with what some others have commented.

Unless you need/want the hybrid viewfinder or WR sealing of the X100V (if you can find one), an X-E body is a good alternative. When it comes to dimensions, an X-E body with a 27mm is very close to an X100V indeed.

Comparison from camerasize.com.

I try to bring an X-E3 with the 27/2.8 WR wherever I go. In a little pouch I'll carry it with an OTG SD card reader either on its own, or add it to any non-photo backpack I might be carrying on the day.

While I don't often carry two X-E bodies at once, I use my bodies to have ready-to-go kits.

• My every-day X-E3 will transition into my street and travel kit, when the 27mm tends to be replaced by XC15-45, and 23/2.0, 50/2.0. I might also add a grip
• The other X-E3 is mostly equipped with an L bracket, and stored with my landscape lenses (esp. 14/2.8, XC 50-230), square filters and tripod

Very rarely, I'll carry two bodies with a lens on each. Sometimes for environments where lens changes are impractical, and sometimes for street shooting if I want to quickly go between 23/27mm and 50mm. It's nice to have handling consistency when it comes to controls, and Fuji X Acquire allows me to mirror settings between my two X-E3 bodies.

Obviously, it's also nice to have a fail-safe, and on any once-in-a-lifetime trip I would bring both bodies.

With that said, neither an X-E nor an X100 will ever be as pocketable as cameras like a Ricoh GR or Sony RX100.
