<p>I have a Sony A7S camera and using a 28-70mm lens. I have been practicing filming fireworks looking for sharp HD type footage. <br> When I tried with the following settings and focus on Infinity the results were slightly out of focus. What can I do to get the crisp HD type video?<br> Settings:<br> MF set to infinity<br> ISO 200<br> F8<br> Shutter Speed - 1/80<br> Thanks for any help you are able to provide.</p>
