Just changed spotters from a Meopta S2 to the Swaro ATX. Had been using my Novagrade without too much issue, but doesn't seem to work as well with the Swaro due to eyecup and size. I am looking for a good adapter that I can use without having to change my iPhone XS Rockform case, and can also be used with my wife's iPhone 12. What is best in the multi phone models that allow me to hook up to the Swaro ATX. Prefer not to buy phone case specific setups. Have considered buying the crazy priced Swaro adapter for my Sony A6000, but like the phone flexibility.
