The champagne waterfall is a standard event in some cruise lines. They stack up a few hundred stemware glasses then pour champagne in the top. On my recent cruise I spent very enjoyable time getting used to my new Sony gear. On this one I used the Sony 55mm f1.8 Sonnar and my A7ii. The first image shows the whole champagne waterfall and the second is a much closer crop of the top of the first image. I think being able to see the bubbles in the champagne illustrates character of the lens. This was autofocus, little thought, just grab the shot at the moment. This lens is amazing.
