I will be in Prague, Vienna, and Budapest.

Plan to take the following:

- E-M1 and E-M5. Don't plan to use both often, but want to have a backup.

I like walking around with two bodies. It saves changing lenses.

- Olympus 9-18. While I have both 7-14s, I like the small size and ability to use regular filters.-

The 9-18 is a good choice.  As you said, it's small, and the wide angle will serve you well.

Panasonic 14-140 Mk II. I'm slightly torn here, because the option is to take the Panasonic 35-100. Both take 58mm filters, so I can use my Canon 58mm 500D close up lens. This is the lighter of the two, and it can also be an all-around lens when I'm traveling light.

I would lean toward the 14-140mm.  Honestly, it depends on exactly where you are going.  I find the flexibility my Oly 14-150 indispensable when I get away from urban areas  -- on hikes and balloon rides and such.  And I don't shoot much at the long end in urban areas.

- Olympus 12mm f/2 prime. I like some faster lenses for shooting indoors, and this is one of them.

It's not that much faster than 12-35mm.  I would skip it.

- Panasonic 25mm f/1.4. My second fastest lens (and I'm not going to take the Nocticron 42.5 f/1.2 due to size and weight considerations). Plus, it uses the same 46mm filters as the 12mm. I could bring the Olympus 25mm f/1.8, but I like the extra ~1/2 stop and shallower DOF. I did swap that stupid lens hood with the shorter one for the 45mm.

Yep.  Good choice.

- Olympus 45mm f/1.8. Good for indoors and portrait. Small and light. Not bringing the 75mm f/1.8, again due to size and weight considerations.

Good thinking.

Bringing some flash gear (FL300R is great for food, FL36R is great for portraits and macro because I can use diffusers). Bringing a 42" ultra-light travel tripod and extensions to mount on.

I took the tiny Oly flash on my last trip and never touched it.  Your mileage may vary.

Bringing a Sirui T-005X tripod (2.3 lbs, <12" long) for night shots and panoramas. Also bringing a panoramic head, nodal slide, L-bracket, and radio trigger with remote shutter cable.

I have taken small, tabletop tripod on trips and never used them.

I won't be carrying all at once (in case you are wondering). The joy of m4/3 is that I can lock this all up in a hotel room safe and just take what I need for a given outing.

That's what I usually do, and it has worked well for me.

Looking forward to getting lots of great shots.

Have a great trip!
