<p>I tried ISO12800 and even <em>ISO</em> 25600 for a few night shots and I've got reasonably good results.<br>

To get the best results, I slightly overexpose (1/2 stop), and later, doing post-processing I correct the exposure,<br>

apply some noise reduction to the RAW file and finally rescale/downsize the image.</p>

<p>I got my 5d2 from www.pixmania.com (price may vary if you select different countries on the web site).<br>

I also have a Sigma 24-70 f2.8 and it is the main lens I use on the 5D2.<br>

I keek reading bad things about this lens here on photo.net but I'm very happy with my copy - maybe I got a good copy or my expectations are too low...</p>

<p>My 5D2 LCD already has some scratches...<br>

And what about dust protection ?<br>

This weekend (http://www.inocam.com/~fjp/RP2009/) I've seen some persons that completely covered their 5D2s with adhesive plastic sheets...</p>

<p>There is some information about EF signals on the WEB.<br>

For instance http://www.birger.com/Merchant2/merchant.mvc?Screen=ef232_home<br>

I think you have motor power / motor ground and then you have logical power + logical ground followed by a SPI interface (CLOCK, DATA-IN and DATA-OUT).<br>

Then you have a lot of SPI commands to read lens type/version, read aperture, set aperture, read current focal length, read focus position and several commands to set/move the focal position.</p>

<p>I had seen this effect on some of the pictures shot with my 400D, but in my case it only happens when the battery is almost empty.<br>

When I replace/charge the battery, it doesn't happen any more.<br>

<p>I've been using the freeware UFraw program and like it a lot.<br>

Version 0.15 will open your 5D2 files.</p>

The 3.9 fps rate is probably

related to compact flash write bandwidth limit

and increased file size due to higher resolution.

I'm just a begginer but I'm already starting to feel some of the limitations in my Rebel XTi,

so I'll probably be buying one by Christmas :-)

<i>I wonder if any of the posters in these threads are actually Canon marketing people. Sure Canon might not like leaks, but I suspect they like the idea of nobody noticing their camera even less.</i>

And I wonder if anyone here have already received marketing info and/or sample copies and are already quietly reviewing it under NDAs ?
