Bad Issues About Canon EOS 7D
Canon has said it is investigating an issue with its recently released EOS 7D digital SLR. In a service notice it says there is an occasional issue where traces of a preceding frame may be visible in images captured in continuous shooting mode. The company says it will release a firmware update to resolve the problem. [ Source ]
By any measure, the new Canon EOS 7D is a worthy successor to the EOS line of APS-C sensor DSLRs. I believe it finally levels the playing field for many Canon shooters envious of Nikon DXXX shooters.
