Not good action shots but wanted to share some high ISO shots. First time ever using with ISO 25600.
This one is a more than 50% crop. Perhaps somebody could do a better job in NR.
D700 70-300f4.5-5.6VR. 1/500s f7.1. Usually ISO 3200 would do the job but not this gym. Light was very poor but wanted to keep shutter speed at 1/500s and so bumped the ISO as much as I needed to.
Zoomed in 100% noise is everywhere. Sharpness looks ok to me though. I think overall, for not huge size web-display and prints of 4x6 or 5x7 should be OK.
