Which M to E-mount adapter are you using?
I've been using the Fotodiox PRO lens adapter for the last 10 months on my A7SII. I'd actually bought it a few months before I bought the camera, when I was hoping to buy a used A7S. I've generally been happy with it, but lately have been irritated by the lens wobble. In fact, I was going to post a question about repairs in Canada for the Zeiss wobble, but then realized most (though not all) the wobble is from the adapter. Noticeable on both my 50mm Sonnar and Planar lenses.
I'm not that interested in close-focus options; a regular adapter would be fine.
Not sure if the wobble has gotten worse, or if I've become less patient about it. My sense is that it has gotten worse.
Who is happy with their adapter, and which one are you using?
