@lisahans Absolutely not Lisa - I have ISO set on auto with an upper limit of 12800... both my Sony and my various Fuji's handle this well as you can see. I could lower the ISO by shooting on a tripod but I like to shoot hand-held.
Wow amazing. And even more incredible that you can do this handheld. I very much doubt I could hold my Canon steady enough for a night time shot and get it anywhere near as sharp and clear as this is. Beautiful colours and reflections
