I have a question regarding light levels while zooming with a DX7590. I do a lot of shooting in high-school gymnasiums, they are well lit with flourescent light. When I am zoomed out the picture in the viewfinder and LCD is fine and the shots that result are fine. When zoomed in the shots in the viewfinder/LCD are fine, but the resulting shots are very dark. Is this normal? Why the disparity between the viewfinder/LCD and the resulting shots?

Are you using the flash on these shots? If you are the difference is in the flash range! The flash is only good for around 20 ft. or so. Also the F-stop wil change as you zoom in cutting the available light that can reach the sensor. You might be a F-2.8 at the widest angle but only a F-3.2 or 3.7 at the zoom.

For the best photos, when using your flash on any Kodak camera, keep your subjects no farther than 12 feet from the camera.

I think Dawg may be right about what is happening is due to the change in f-stop between wide angle and telephoto - less light at the telephoto setting. Your stating that the gym is well lit makes me think you are not using flash. The built in flash is useless anyways over 10 or so feet. Are you using the AUTO setting - is the lighting bright enough? If using one of the other settings such as Aperture or Shutter Priority make sure your exposure settings are correct - no underexposure at Telephoto setting. The LCD viewfinder in my Z7590 is always bright no matter what the ambient lighting is, but the picture taking CCD will only see the available light.

You can use it in manual mode and set the ISO to 200 or 400 and then slow the shutterspeed till you get the photo you want. The camera will still only let you have a 3.2 or 3.7 F-stop with the tele zoomed outbut the faster ISO and the shutterspeed adjustment will allow you to shoot in even very low light. The higher the ISO, though the more noise will show up in the photo in the form of off color pixels distributed in the photo! Also the slower the shutter speed the worse the action shots will turn out as the shutter may no longer be able to stop action and shakey seemingly out of focus shots will occur if you don't have a steady hand or a tripod! Just a thought!
