Question about Nikon 28-70mm F2.8 ED-IF AFS Lens
Nikon AF-S Nikkor 28-70mm f/2.8D First, the aperture diaphragm is stuck at small aperture setting and aperture diaphragm blades do not open up when you adjust the aperture ring. Second, the AF-S motor makes squeaking noise when you start the autofocus but the noise will go away after some use. The autofocus functions well but because the aperture is stuck at small setting, there is not enough light going through the lens, thus the camera can not lock the focus

I just had the same exact problem! However, in my case I was finishing up a photo shoot at work, went to switch lenses, and when I picked up my 55-200mm zoom lens, the tip of it fell off!! I was able to put it back into the end of the lens, but now I am having the same autofocus problem and sound effect. I think it is because it is off track inside the lens. But I have only had mine for 5 months! I'm preparing to send it to Nikon for warrenty repair.

I have the Canon 24-70 f2.8 L lens, and there's no way you could ever get me to exchange it for a sigma lens. There's no question that this is a very excellent lens.
Why are you considering the sigma lens?

Is the switch on the side of the lens set to manual or auto? Sometimes it's the little things like this that we don't notice.

You might like to check if the A/M slider switch on the lens by the Nikon label is set to A.
It sometimes gets moved accidently.
Set to M the lens will not autofocus.

the lens internally has a electrical circuit ribbon that contracts when you adjust the lens everytime. They are prone to get crease causing a short in the auto mode.b It can be checked and replaced bt most camera technicians
