After I bought 6000 I unfortunately had the eye cup for my Sony alpha notice that not a single adapter for the Sony case was .... Apart from that the other adapter all together are cheaper scrap !!! Although I was an exchange offered by the seller ... but for 13 EUR parcel printing, packaging, bring to the post office and ship does not pay. Property me then even marked an adapter and printed with the 3D printer ... now the eye cup fits perfectly on the Sony Alpha 6000 :) The rest will come in the bin !! Unfortunately, you can not be '0' star ... about 1 out of 5
