Hi Derek. Welcome to justanswer.
Try another lens and then check if the issue is still there
How old is your camera?
The spot is caused by the dust which has got trapped inside the camera and onto the CCD sensor. You will need to get it cleaned.
You can get it cleaned at any local camera repair shop. If you want to do it yourself then I can provide you a video for guide. Let me know if you need one.
