is this normal?
At 300mm wide open, you have an aperture of f/9.86. Maybe you just don't have enough light to make the picture.
It's possible that the lens combo is simply underexposing, or maybe there's something else going on. We can speculate all day, but we won't know until you post samples with exif intact.
