I own the Nikon Coolpix 4500, and now that baseball season is here, I can't wait to get out and take some close ups, and since i won't be sitting on the first row, I need to be able to zoom closer. my camera has a sorry 4x optical zoom. i have a telephoto lens by digital optics, but i'm not at all impressed by the addition of zoom.
does 2x mean that it effectively converts the camera into 8x instead of four?
am i missing some of that because it is a cheap lens?
also are there lens out there that would give me 10 times zoom for my camera?
also one more question i saw a close up kit advertised.
what is a diopter and what does 1x 2x 4x mean?
i know these are noob questions, but if someone could answer a few of them even it would be greatly appreciated. thanks

I dont know how helpful this will be but heres what i know.

Yes. Depending on the quality of the lense will determine how crisp and clear the pictures will turn out. There is a great difference in brands of lenses.
also one more question i saw a close up kit advertised.
what is a diopter and what does 1x 2x 4x mean?
i think the diopter is a knob or button on your camera that adjusts the eyepiece veiwfinder to be in focus. Its usually right above the eyepiece.
Basically these kits are only for use for macros. 1x 2x 4x magnifies the subject being photographed by that many times.
Its like holding a magnifying glass in front of your lense. You have to get a good brand of these as well to get good shots. I bought a $20. set and the pics didnt turn out so great.

The quality of your telephoto lens may be worse than the original optics, but also I think camera shake may be the culprit. I bought my first camera, an Olympus C720Z, on the strength of its 8x times zoom. What I found is that the sharpness of hand-held shots at maximum zoom length rapidly deteriorated, because even the slightest movement, even things like breathing magnified the camera shake - you can't see it on the LCD screen, only when you view the picture on your computer. So I couldn't use the full zoom effectively without a tripod.
Obviously if you are taking sports pictures you are in a hurry to grab a shot, you move a camera ever so slightly - with dire results. So there may be nothing wrong with your digital optics telephoto extension, you just need to adjust your shooting technique.
I do not know if they allow to bring a monopod to a baseball game (have never been to one), but they are normally compact and expandable and great to stabilize the camera in telephoto. Otherwise try to be absolutely still, do not shoot looking at the screen, press you elbows closer to your chest and look through the viewfinder, take a deep breath before taking a picture, that's sort of thing.
Cheers

The other thing you can do to help with camera shake is to shoot in shutter priority mode. This way you can set what the shutter speed should be and the camera will set the aperture to try and maintain that.
The general rule of thumb is that your shutter speed should be faster than the reciprocal of the 35 mm equivalent focal length of the lens.
So if you have a 100mm equivalent lens, you need to shoot at about 1/250s or faster to avoid camera shake issues. If you zoom in to an equivalent of 200mm, you need to shoot at about 1/250s to avoid shake and so on. The longer you've zoomed, the more it magnifies shake and the faster your shutter speed needs to be to compensate. If you are shooting sports indoors, this speed can be quite hard to achieve, with an acceptable ISO value. Monopods help somewhat, but mainly to support a heavy camera - you need the speed to try to stop the motion of the players anyway - something a monopod obviously doesn't help with.

i'm thinking about an outdoor park, so i'm thinking those shutter speeds are definitely attainable on a clear day.
my question about the telephoto extension mainly is will a higher quality lens give a better zoom possibly?
