Nikon D5200 owners .... Help please

[bbg404]

Afternoon all I've posted about this problem before ISO noise but I've just done a test in the house and I'm wondering if any of you kind D5200 owners would do the same to compare results before I contact Nikon

Thanks

What exactly is it you're asking?

Basically take a photo with the lens cap on using these settings

RAW
F22
30 seconds
ISO 3200

Just just zoom in as far as you can then move as far to the bottom left and see if it shows pink noise!
I think mines showing a lot more than it should
