This is the lowest price I have seen on a new, USA warrantied, Nikon D750 so far. As a bonus they include a $250 Audio Technica camera mount microphone for no extra charge. I've you've been waiting for a price drop on the D750 this might be what you've been waiting on.
Do I like the D750? I have one packed in my bag for my upcoming shoot. It's a great, full frame camera that is really good at high ISOs and killer at ISO 100.
