<p>[QUOTE=&quot;rmpsrpms, post: 1540518, member: 31773&quot;]For each camera, the degradation between Live View and Normal is due to Mirror Slap vibration. The vibration is happening within the camera itself, so no way to dampen it externally. </p><p><br /></p><p>The Normal sequence is: Shutter release (time delay, PC tether, wireless remote, etc); Mirror rises, inducing &quot;Mirror Slap&quot; vibration; first shutter curtain opens, inducing &quot;Shutter Shake&quot; vibration which adds to the overall vibration; exposure; second shutter curtain closes; mirror drops.</p><p><br /></p><p>In contrast, the Nikon Live View sequence is: Shutter release; first shutter curtain closes; photo sites are extinguished; first shutter curtain opens; exposure; second shutter curtain closes; mirror drops; mirror rises. </p><p><br /></p><p>The Canon Live View sequence is: Shutter release; photo sites are extinguished; exposure; second shutter curtain closes; mirror drops; mirror rises.</p><p><br /></p><p>D300 and D7000 have similar shutter mechanisms, so should produce the same amount degradation. I believe both have a single motor that runs the shutters and the mirrors, hence the need for the mirror to cycle even in Live View. I further believe that most or all Nikon and Canon full frame cameras have independent motors such that in Live View only the shutters actuate. </p><p><br /></p><p>The amount of degradation due to vibration is very dependent on shutter speeds. If the shutter is very fast, the effect is smaller, but can create a &quot;smear&quot; effect since the vibration may not have many cycles to average out the effect and the fast shutter can catch just a single or even partial cycle.[/QUOTE]</p><p><br /></p>
