I don't know these cameras very well. Are they point and shoot cameras? They will probably be fine as long as you don't need to take rapid shots. What I always do when I want to know if something is decent enough to purchase is I do a Google Review search (i.e. "Nikon Coolpix P100 Reviews" on Google). You will find lots of reviews from actual users. That's how I made my choice on my camera.

Both of those cameras are good point and shoot cameras. Always remember you get what you pay for. Both those cameras will serve the needs of most amateurs, or aspiring serious hobbyists. I've taken some pretty neat sports photos with point and shoot cameras. Their main advantage is ease of use, size and weight, convenience. Disadvantages are they are slightly slower and have smaller sensors than a DSLR. (by slower I am talking fractions of seconds) Your newer DSLR cameras will give you more latitude in shooting in low light and speed, and larger sensors and interchangable lens.

A good photographer can take any camera and take a great picture. A poor photographer can have the most expensive camera on the market and take a bad picture.

You can get unbiased camera reviews of the most popular cameras on some of these sites:

OK. I´m a poor photographer, LOL. I have a Sony W35 and I like it, I can carry it in a pocket and the photos are fine. But I´d like a camera wich I could take photos with more zoom, in example, in a theatre from the seat 10. And I´d like if it would shoot faster, my camera is pretty slow (I shoot but then the dog is not in the scene, hopefully only his tail, LOL). I don´t understand the technical specifications. I would not want to buy a camera and that the photos be lower quality than with my old Sony or equal... How do I know if some of this two can shoot faster than mine? Thank you so much for your help.

By faster we mean the camera's reaction time from the time you push the shutter down all the way to the time you can take the next picture. Either of the cameras you mentioned will be able to shoot fast shutter speeds, however some cameras take longer to process that picture before letting you take another. You can also take on what they call continuous mode. This allows you to take a few pictures while holding the shutter down, and some will take 3 - 5 while others might take 6 - 7. What you need to do to find out what a specific camera is capable of, you need to read the Specifications and reviews when looking them up. Hope this helps you.

I have a panasonic lumix FZ28 an amazing camera and well worth a look at..18x optical zoom..photos are amazing...
