This gallery is strictly so others can compare different lens. I have the Canon Pro90IS, which has a 10X optical zoom. Additionally, I have an Olympus B-300 and Olympus TCON 14. Both are very good lenses. You will see here examples of using the camera with just the B-300 and also with it stack with the TCON 14 (order is Camera, then TCON 14 then B-300). I just barely bought the TCON 14 (January 2003), so these are purely experimental, not high quality. When I do get some higher quality, I will put them under the appropriate Gallery. For exact comparisons, distance has remained the same (from subject).
