I am looking for help, I wish to buy a new Canon Camera but I cannot decide between the foregoing cameras. I am looking to take photographs for pleasure, landscapes and Macro. Having looked at the PhotoPlus Buyers Guide I am looking at the Sigma range of Lenses. I can see the additional features of the Canon EOS 7D, but I wonder whether the body only price difference is worth paying. Can anyone please give me some help on this matter.
