I've got some business and family travel (to urban areas) coming up this year, and I've decided that I "need" a compact for this purpose. M4/3 is a lot smaller than my SLR was, but it still needs a bag with lenses and I just have a hard time bringing those along for meetings, etc, so I have it in the evening for walk-around sight seeing. And for family travel, I have 4 kids, so I really just am to the point where I can't have another bag or take time to swap lenses. It really ends up being a point of contention at times. I don't want to go over $700, so that kind of eliminates the RX100 IV/V. But I see major pros and cons for each of the remaining options. ZS100 has a great zoom range + EVF, but is it too slow aperture to be all-around? LX10 has a fast lens and great 4K features, but no EVF or ND filter. RX100 III has an EVF and fast lens, but no 4k. G9 X is cheap and super pocket friendly, but no EVF or 4K and lens is slower. Any advice on which one to choose? Again, this would be primarily just used for walk-around travel and family trips/outings. And if I was going somewhere that photos would be a primary purpose I'd still bring m4/3.
