This time the references concern the Canon EOS 50D Digital Camera and its companion the Canon BG-E2N Battery Grip
Both were depicted and referred to, in many of the illustrations of my articles about Panoramic heads, Nodal Rails and Macro Rails.
Besides detailed illustrations, there you may also find more information and reviews in the "Relevant Readings" section at the end of the article.
Update May 2013
However, the very recent announcement from the Magic Lantern add-on software team about unlocking the hidden RAW video capabilities of this fine camera will bring it forward once again.
I hope you find the references useful, thank you for viewing.
