I attached 2 pictures of my son in Karate. 1st pic My Son is on of his top of his karate partner Grappling. 2nd pic my Son is throwing a kick at his sparring partner. I used a Nikon Z9 w/70-200. 2.8 lens. ISO 2800 Aperture f4 Shutter 1/250. No flash was used. The lighting is fluorescent and is very different depending on where my son is on the mat. Hopefully this helps.
I see you responding to Hoggers and you still haven’t posted any pictures. So I’m not sure that this isn’t a scam. So I’m no longer interested in the Nikon 28-70mm f/2.8 lens. Good luck.
