Hey Peter!
Did you see that Canon released the firmware fix yesterday for the Black Dot conundrum? Yahoo!
Andrew Yip, a nature photographer from the Pacific Northwest, did a side-by-side of images before and after installing the firmware update, and the black dots are GONE.
I have the link to his comparison and the firmware on my site.
Thanks Paul! What are you waiting for? Scoot on over to canon5dmkii.net and check out the Andrew Yip’s side by side comparison.

Hi Peter!
My site, Canon5DMKII.Net, is officially kaputz now. I want to thank you for featuring it so often! I’d like to spend my spare time (the little there is) shooting my 5D2, and learning Premiere CS4. I’ll let you know when my first movie done!
Paul
Thanks for all the cross-linking and support Paul! Hope you have fun shooting with your 5dmarkii!
