...One of the new features stated in the ability to switch from manual to bulb automatically instead of prompting you to change it on the Canon 5D Mark II.
Thanks for the link. I looked at the website and did not see any updated reference to the bulb function with the 5D Mark III, which I have. And one of my favorite HDR shooting situations is around twilight and later, requiring shutter speeds below and above 30". I read the manual that was unzipped with the firmware upgrade and I am still not clear on whether the Promote Control would work automatically with the 5d Mark III.
Can I assume, if it will now work with the 5DII that it will with the 5DIII?
