I emailed Canon regarding lack of exposure compensation in manual mode on the 5D3. They sent me the reply below. Hoping for a firmware update to correct this issue. If anyone else has an issue with this, please consider letting Canon know your position. I find this seriously limits the camera's usefulness to me as a bird photographer.
"Thank you for contacting Canon product support regarding your EOS 5D Mark III. I understand you are interested in exposure compensation when shooting in manual mode. I am happy to assist you.
You are correct that this model does not have exposure compensation in manual mode. This is something that I can submit to our engineers for consideration and may be incorporated in a future firmware release. Please note that decisions to include a particular camera feature are made by our engineers and product designers in Japan, based on a number of factors. Consumer demand, technological limitations, and customer feedback are all taken in to consideration."
