Joseph, No Worries, it's just money <vbg>. I have to say that I really do think that Canon's lens quality has done down some since the advent of digital. It to me is an afterthought. Digital cameras are based on an old design, the 35mm SLR. I can't wait to see what the future brings in size and shape and capabilities of new gear. I really do think that the optical viewfinder needs to go. It takes up too much space with the mirror box and such. if our cameras did not have optical viewfinders we wouldnot need mirrors and lenses could be alot smaller in size and weight. If the chip is smaller why build this huge darn camera around it? We would have far fewer dust bunnies inside without haveing to change the lenses so much. Just think we could have a camera nody with a 10mm to 600mm lens builtin with a a frame rate of 24fps and each file is 60 megs or better 1gig!! Not so far away I think just modify a video camera....

As you will have the chance to see, I have posted a message to the group earlier today that actually explains the solution I've found to the problem. Your suggestions have been very helpful and I will follow some of the suggestion you have shared with me here. My setting for sharpening is also set for the factory's default but I am going to look at it and see if changes can actually improve the results I am obtaining. Very good point.
