About 10 days ago I went to a music festival at which my granddaughter's high school String Symphony was performing. After I decided to use my NEX-6 and A6000 for video, I obviously needed to rent an A6300 for still photography, and here are some available light images taken with that camera and one of my old Minolta 70-210mm f:4.0 "beercan" lenses. When looking at the results later, I was quite surprised by the low noise of the A6300 images at ISO 6400. My very rough and unscientific estimate is that the A6300 is about 1.5 stops better in low light than my A6000. I have no idea what Sony is claiming for the camera, but that is what it looks like to my uncalibrated eyeball. BTW, it may be a real challenge, but guess which one is my granddaughter. FYI, all of these were shot with the lens wide open at f:4.0, which created the shallow depth of field, and my focus point was intentionally varied depending upon my goal. And finally - as a bit of irrelevant trivia - the piece they were performing at the time was Vivaldi's "Winter"
