Check out the Digidapter. It is advertised on several birding forums. It's fairly expensive for a digiscoping adapter, but it is well made and works well. It is not really 'quick' to set up, but once you have your camera connected, it is a solid attachment. I have a sony A6300 and a Swaro STS and it works well with my setup. Disclaimer, I am a novice at the remedial level when it comes to photography.
I use the Vortex adapter for my Sony RX100 III. I needed to attach the threaded filter adapter to my camera then the appropriate ring for the Vortex adapter. Fairly quick and works well.
