Our entertainment last night was Cormorant’s Fancy. They were very good. You can click here to view their website and listen to their music.
My purpose in taking these pictures was to see how my 23mm F2 prime lens on my X-Pro2 camera worked in this setting. I was sitting in the middle of the audience for the one image but got up and walked to the back for the other. I then cropped them both a little. The closer image was taken at F2 and ISO 500 but the other was F5.6 at ISO 5000. No doubt that the ISO 500 had better detail and less noise. If there was only a single performer I would need to use a longer, but fast lens.
