What is the best all-around travel lens for Micro Four Thirds systems?

Question

I’m finally planning a long-awaited trip to Japan this autumn, and I really want to stick to my Micro Four Thirds setup to keep my pack as light as possible. I’m currently using an OM-5 body, but I’m having a hard time deciding which lens should be my primary "walk-around" glass for the duration of the trip.

I’ve been eyeing the Olympus 12-100mm f/4 IS PRO because the reviews are incredible, but I’m a little concerned about the weight and whether it makes the kit feel too front-heavy for all-day trekking through cities. On the other hand, the Panasonic-Leica 12-60mm f/2.8-4 seems like a fantastic, more compact alternative, but I wonder if I’ll constantly miss the extra reach of a true superzoom. My travel style usually involves a mix of wide landscape shots, busy street scenes, and the occasional low-light temple interior. Weather sealing is also a major priority for me since I want to keep shooting even if it starts drizzling.

I’ve spent hours comparing charts, but I’d love some real-world feedback. For those of you who travel extensively with MFT, what is your go-to "one lens" solution that balances image quality with portability, and how does your choice handle those tricky dimly-lit situations?

In my experience, I’d actually go with the Panasonic Leica DG Vario-Elmarit 12-60mm f/2.8-4.0 ASPH. POWER O.I.S.. Over the years, I've tried the Olympus M.Zuiko Digital ED 12-100mm f/4.0 IS PRO, but on a small OM-5, it feels SO front-heavy. That extra light at f/2.8 is basically essential for dim temples, plus the size is just more balanced for 20k-step days. Trust me, your neck will thank you! gl!

For your situation, I'd actually suggest looking at the OM SYSTEM M.Zuiko Digital ED 12-45mm f/4.0 PRO. I know the Panasonic Leica DG Vario-Elmarit 12-60mm f/2.8-4.0 ASPH. POWER O.I.S. and the 12-100mm were already brought up, but for an OM-5 body, the 12-45 is basically the technical winner for portability. It weighs just 254g—thats literally half the weight of the Olympus M.Zuiko Digital ED 12-100mm f/4.0 IS PRO. On a long trip to Japan, that balance matters more than you'd think. The 12-45 is IP53 weather-sealed, so it’ll handle the drizzle no problem. Tbh, f/4 isn't the fastest for low light, but since the OM-5 has such insane IBIS, you can usually just drop your shutter speed for those temple shots. Its much sharper than the superzooms, too. If youre really worried about low light, maybe throw a tiny Olympus M.Zuiko Digital 17mm f/1.8 in your pocket for nights. Honestly, keeping the kit light is the best way to enjoy the trip. gl!

I'd actually suggest a different approach - honestly, I've been in ur shoes before. I once lugged a massive, expensive 'pro' zoom through Kyoto all day and by the afternoon, my neck was killing me... I literally ended up just using my phone lol. It kinda ruined the vibe. For a body as small as the OM-5, dropping serious cash on a heavy lens seems counterintuitive if u want to stay light. Basically, u're looking at a huge price tag for reach u might only use 10% of the time. Before I dive into more technical specs, what's ur actual budget for this trip? Also, r u planning on carrying a tripod for those temples, or r u relying purely on the camera's stabilization? I've found that for low light, even a constant f/4 can be a struggle if u dont wanna crank the ISO too high. Sometimes two smaller, cheaper lenses actually provide better value than one heavy 'do-it-all' glass... anyway, let me know!
