Question about Sony Np-Fz100

No or not directly. However, you can use the battery with the multiple battery adapter set (NPA-MQZ1K) with the A7 II (unfortunately not available at Digitec). However, you will have to decide for yourself whether this makes sense in terms of price (at least CHF 400) and connection technology (huge part).
