I wasn't using a tripod at the time. I have in the past, but left it at home. As for grain in the pictures, I have it set for a very low recording quality so that I can keep the images somewhat larger.
To each their own, I will sacrifice less pics on the card for the best quality.
Honestly, the focus could have been better, but I had to switch to manual focus on my digital camera since the auto focus refused to "hit" the right target. It was very frstrating! My camera almost learned how to fly, before id decided to not throw it!
