I guess it depends on what you are doing. The Nikon is 5 megapixels, which is overkill unless you want really large prints (a 3mp can do 8x10s fine) or if you want to crop photos and make them seem 'closer'...it's also 2x the price of the 3 mp Olympus. We have a Nikon SLR camera, no complaints. Also had an Olympus digital camera, but the model was years and years old, so it's not really relevant now. If I had the money, I would buy the Nikon (they usually have great macro capabilities)
Something to know about high zoom, though. The higher the zoom, the more prone the image is to blurring from camera shake. I have a 10x optical zoom digital camera (Canon pro90 IS), and it's great. However, it does incorporate image-stabilization...here's an example...
Here's with the image stabilization...

Here's without...

These are just crops of the full picture, no resizing. The quality's a bit low, because the pics were too dark and I had to lighten them a little. But you get the picture.
Here's some headshots I took:


^Just resized. The only problem I have with my camera is that there is no built-in macro function. The above shots were taken with the optional close-up lens.
