do you mean on organizing your photos?
lightroom is a very good photo organizing suite.

or you mean putting your copyright/label/keyword inside your photo's EXIF?
if so, then you can try program called Exifer. it's free and it does what you want to.

hope it helps

First thing first, what system you are at? and what is your budget as well. Try posting in http://forum.lowyat.net/topic/1247191 instead. You will get better responses there.

Well, back to the topic

Here's my little pet project called mylensdb.com

You can explore some of the photos taken by those zoom lenses grabbed from flickr at my project site here. By then you may get the rough idea on what you can expect from the particular lens. Also, you can find photos by body as well as by lenses. You may also check prices there too.

Hopefully it will help you somehow someday sometimes.

read up and you will know what you need to know

UV
A multi-purpose fine-weather filter
Absorbs the ultraviolet rays which often makes outdoor photographs hazy and indistinct. A multi-purpose,
fine-weather filter for color as well as black and white films. Also serves as a permanent lens protector.

CIRCULAR PL
Color and contrast enhancement
Light rays which are reflected by any surface can become polarised so polarising filters are used to select which light rays enter your camera lens. CIRCULAR PL filters allow you to remove unwanted reflections from non-metallic surfaces such as water, glass etc. They also enable colors to become more saturated and appear clearer with better contrast. This effect is often used to increase the contrast and saturation in blue skies and white clouds. HOYA's polarising filters do not affect the overall color balance of a shot.

I don't see why not. It's all about the person behind the camera!
