You are in luck.....both cameras have been reviewed by the same reviewer.
Here is a link:
Notice the green link right under the photo of the camera.
That takes you to a full (multi page) review of the cameras.
Also notice the red stars in each column.
That is the rating given to the camera by owners of the camera.
Right under the red stars is a link that takes you a page where you can read what the owners have to say about the cameras.
Which camera should I get? Casio Exilim EX-V7 or Panasonic Lumix TZ3?
I know that the Panasonic has 10x optical zoom and the Casio only has 7x, but there are pros and cons to everything.
I would prefer is be small enough to fit in my pocket, the Panasonic won't, but it isn't a must. Also, which one has the best image quality? I don't care for the Panasonic as much because it doesn't have as many manual controls on the outside of it. Or as many modes. I also like on the Casio that the lens stays inside the camera and is still a pretty good 7x optical zoom. Just please give me your opinion and the reasoning behind it, and I thank you very much!!
