M3/M5 I assume is Canon but they are not PnS. They are mirrorless in case you missed that. Though they are small, you still need to carry lenses. If mirrorless are your way to go, Olympus or Pana would be in favor for me as lenses is exchangeable between them. 2K budget might be limited lah.

If 2k is your budget, PnS you can a Olympus Tu range of cameras (slim) or hyper-zoom cameras (bulky). I guess slim one better since you use it for travel.

I just bought RX100-3 recently after my 100-2 spoiled after 3 yr, I am using it only for traveling casual shooting purpose. Yes I am a happy return customer to RX100.

Reason for not going for mk5:
1. cost (!!!)
2. not really need all those feature, end result quality not too much different.(for my skill level)
3. Mk5 battery life is crappy compare to my deceased Mk2, I just can't accept that nor i willing to carry more battery during traveling.

I would recommend the RX100 m3 for budget + reliability + quality. It's been my go-to travel camera... until I got myself the Google Pixel 2 phone. I've been trying to just rely on my phone to take photos these days. Hence, if you're keen on a 2nd hand RX100 M3, let me know it's just sitting in my drawer not using it - don't mind selling it to someone who would use it more

I'm using RX100, my sister using Canon G7x

I think you can consider RX100 III, G7X or Panasonic LX10 or LX100.

RX100, G7x Mark I or Mark II & LX10 have same sensor size (1")
LX100 has micro4/3 sensor size, which is almost double of 1", with very bright lens (F1.7-2.8, focal length 24-75mm) but 12MP resolution output, and this model quite old.

? How u planning still when skiing?

Mirrorless (unless lastest A7 sony series) battery kinda suck in cold. Would probably consider old mirror dslr for the job.

Like i said, any mirrorless (unless the lastest model with bulky grip) will have same problem. However i believe if worse come worse probably reduced to 200 shots in freezig temperature (have to check specs) so should be enough as long you dont go trigger happy. However i belive rx comes with usb charging so bringing a powerbank would help.

Secondly......may have to take note, if you wearing glove, have to take out everytime using that smallist rx100. Or get a add on grip.
