Thanks Dave and David, I tried the E20 on a simple construction boot product shot on white at a 3/4 angle. I was never quite able to get the front of the boot and the rear of the heel completely in focus. No matter where I tried to focus (one third into the image etc.) there was always some part of the boot slightly soft. I also tried to used the zoom lens in less of a telephoto length but found it distorted or exaggerated the lines of the product too much. I finally ended up using a Fuji S1 with a 24 to 120 zoom (I cannot really remember the lens) and had none of the above mentioned problems.
