My gut feeling is that you are correct Setiprime, when you say that we are used to the oversharp images from prosumer cameras. I think that in order to put this to rest, I will have to just buy myself a good lens. I am holding out for the Sigma 70-200 2.8 and maybe a prime lense like the Canon 50mm 1.8 I keep hearing so much about.
Thanks everyone for your comments. I have done a few side by side shot to compare my old Pro90 to my new 20D. I obviously lowered the resolution in photoshop to match the two closely. I cannot believe the difference. It is absolutely amazing! I will never recommend a consumer level camera to anybody semi-serious about photography. I have taken some pretty nice shots with my Pro90 but I think that when challenged with difficult contrasty lighting, the SLR really shines through. I will post some images shortly to show everybody my results.
