Moving to Mirrorless: G7, GX7, E-M10 II, E-M5, A6000

Recently sold all of my camera DSLR gear and making the move to Micro Four Thirds / Mirrorless. The primary reason for this move, as I think is one of the huge benefits of this system, is size. I enjoyed my DSLR, but I hate carrying it and the lenses everywhere. I end up using nothing but my camera phone on hikes because I never want to lug all the gear.

I primarily photograph portraits, street, and landscape. The camera systems mentioned are in the price range I'm looking for (including refurbished)..

G7

GX7

OM-D E-M10 II

OM-D E-M5

A6000

I've used the A6000 previous on a trip to Utah, Colorado, and California... the size was great, I enjoyed the system very much, but the lenses just don't seem to be there. Aside from the kit lens and a few primes, anything else seems to be quite expensive.

Being able to utilize adapters is also great, but won't be the main range of lenses I'm looking at. I like sticking to those 4/3 meant for the systems to keep the whole package small. However, ability to utilize an adapter for a nice wide angle lens or telephone down the line for specific shots would be great.

I know G7 excels at video, but video is not my primary use (however, I do want quality video for those few occasions). The articulating screen could be useful as well.

OM-D line seem to excel with image stabilization, which would be quite important in lowlight situations with lenses.

A6000 is great, like I said, but affordable lens selection seems to be the pitfall here.

Anyone with hands on experience or suggestions would be incredibly helpful! Thanks in advance
