Here is the small kit I'm taking for this weekend. Plans are to shoot family indoors, a concert at a park, and hopefully a few decent landscape images.
The camera is an e-M1 and Olympus 17/2.8 lens. For indoors and lightly cramped family the 35mm/e should do fine. A small RRS-style plate is attached to the camera.
In the small bag is the Laowa 10mm/2, Oly 14-150ii and TTArtisan 23/1.4. Those will cover any low light and long images if we're late to the concert and must hang out in back. Included in the bag are a polarizing filter, two batteries and a plug-in microphone whose mount is sticking out in the photo. I should bring the flash for extra security - luckily I have a spare pocket on one side that's doing nothing :^).
This plus a tripod or monopod should be sufficient!
