Yes but Don, the Sony A100 is not a professional dslr. I think it's more comparable to the XTi. Besides, many will point out the image stabalization of a Sony isn't as good as lens IS. Such things as composing a shot are different with in-camera stabalization.

For the prosumer market, your advice is great. The Sony A100 with it's IS is better than no IS but I feel it's useless to compare it to a Canon IS setup. Sony hasn't yet made a camera with in-body IS that is comparable to a pro camera. Until they do, professionals will choose Canon (or Nikon).
