I have a Cannon Digital Rebel XT, and need a digital zoom lense that will work for taking indoor swim meets. What are the points I should consider when purchasing a lense.
Answer
The requirements you have spelled out comes under sports photography. Most people do not realize it is not the lens but how and were it's used. It's unlikely that you will be aloud to get very close to the athletes and the lighting environment is going to be bad to say the least. If you want to focus in on one athlete you will need a long focal length lens , say, 400mm to 600mm. On the other hand, if you want a photograph of the entire venue, a wide angle lens is what is called for, 18mm to 28mm. I have yet to meet a lens that zooms from 18mm to 600mm. But if one does exist, the price will that of a small new car.
The best advice I can offer is: RENT a 400.mm f5.6 lens and a tripod with a ball head that can hold it up without collapsing. A fixed focal length wide angle lens around 24mm will do for your panorama photographs of the entire pool. Now for the bad news,
your automatic light meter in the camera will be completely confused by the bright reflections off the water surface and underexpose your photographs, you will need to figure out an exposure for neutral grey using the fastest shutter speed you can get away with. Manually set the exposure as per your camera manual instructions and do not change it no matter what your camera says, Set It And Forget It.
To see these high performance lenses in action, turn on your TV and tune into live sports events and pay attention to the sidelines, you will see the Pros hard at it, to take the perfect photo it in time for the morning edition.

How do I take a picture in which each water drop could be seen in a picture ? Slr camera or digital both ?
Answer
Your question sounds very odd.... "the water effect"?
I am guessing you might be asking about how to freeze action. That's when the shutter speed is so fast that you "freeze" movements such as individual water drops in a water fall..... is that what you mean?
In that case, all you need is fast shutter speed, which is possible with ANY camera, just as long as there is plenty of light around. DSLRs give you a lot more scope with their fast lenses and higher ISOs, but it can be done with a P&S, too. Of course, it can be done with SLRs (i.e. film), as well.
However, if you're trying to catch action such as in sports, then the P&S's shutter lag would drive you crazy.
