7D strange issue

<p>This is an very strange but reproducible issue with out new 7D. I noticed that sometimes my video buffer fills in just a few seconds and recording stops. If I start the recording again, it records with out issue and the buffer preforms as expected. This exact order of operation will cause the issue without fail.<br>

1. Turn on camera<br>

2. Switch to video mode<br>

3. press record<br>

If if take a still or view images on the card between steps 1 and 2, no problem.<br>

I am using a 8 gig UDMA Delkin card. Any ideas? Can you reproduce the same issue? Should I call Canon? Your help is much appreciated.</p>

<p>I'd call Canon. Perhaps it's a known issue to them (though I haven't heard of it).</p>

<p>I've used the video mode straight away many times on my 7D without any such issue, but with 8GB SanDisk Ultra (30MB/s) instead. Perhaps you have a defective Delkin card? Or maybe your 7D needs service? The 7D has been out for 3 months so bleeding edge photogeeks would have screamed bloody murder long ago if such a glitch existed.</p>

<p>Same happens to me but while I am taking video(sandisk extreme IV 30mb/sec) 24P, 1080P, slowest shutter speed, widest aperture, and high ISO. Buffers fill up rapidly after I take a snapshot while taking video. But also has happened with previous condition just shooting video for less than 4min. I think its due to the slowest shutter speed, aperture and high ISO combination takes up much more memory than shooting in bright sunny conditions.</p>

<p>I will call canon about this one as well.</p>

<p>What you are experiencing is how quickly your 7D has become obsolete. I will gladly take it off your hands for 100 bucks. No seriously, Call Canon right away, like the fellow posters have said. The issue is probably know to Canon already.</p>
