Was about to upgrade my firmware for my Nikon D - 5300.
Then I read that a person that did it had caused his lens not to work on his camera.
I contacted Nikon, they said …
"we do not guarantee the use of 3rd party lens's on their cameras".
Since I am using a Sigma lens, I now have concern's of upgrading my firmware.
Sooo, what is your opinion on this ??
Has anyone else had this happen ??
Please advise.

I had this happen to me last year when I downloaded an update for my Nikon D800 camera. After the firmware update my 35mm Sigma 1.4 Art Lens would not autofocus. I contacted Sigma and they suggested two options : they would update the lens for a small fee or buy the Sigma docking station to update the lens software myself. I decided to buy the docking station and now the lens has full autofocus function again.
