Hi ats-david, congratulations on your purchase. To get the most out of your full frame camera be sure to experiment with different exposure modes. I'd recommend starting off with aperture/shutter priority and then moving on to manual mode once you're familiar with the camera.
If you're already used to using manual exposure modes, then be sure to take advantage of the increased low light capabilities that full frame sensors offer. You'll be able to drastically increase the ISO with minimal image degradation, this will allow you to use a faster shutter speed for action or wildlife shots, resulting in sharper images.
There are many more tips that I don't have the space to include here, but I may well write a blog concerning "getting the most out of your camera" in the near future, be sure to look out for it. I hope you enjoy your purchase.
