This is the first video of two I made for a Side By Side between the Canon 1D MarkIII and the 1D MarkIV.The idea is to show you some outer side comparatives between the two of them without getting into much of a review. I'm pretty sure there will be plenty of places to check for reviews but the idea here was to see the side by side as a all and identify the shell differences and improvements that Canon brought us.Hope you enjoy and check the lightingmods.blogspot.com for more information.
