I think reading reviews and users comments (if the lens is listed here) is a good starting point.

See the 2 forums here on Lens Review Database

I guess if you stick to the known brands you wont go far wrong, it all depends what it is your trying to achieve.

It's very easy to get caught up in the whole lens thing, remember at the end of the day it's all about the image, not the equipment used.

Enjoy your photography.

f number is the most important thing (thats f/2.8 or whatever). it tells you how much light the lens gathers, so how good it is in the dark. Other than that it is very hard to tell how good a lens is.
The best advice probably is to go to a shop and try it all out!!!

I beg to differ. There's horrible fast lenses, and then there's the wonderful slower lenses. Optical quality is much much more important (IMO) than wider aperture.

Rule of thumb: Expensive lenses are better.
The game: find exceptions to the rule.

This thread hasn't quite run its course.

You can rely on measurements of optical characteristics from websites.

You can trust a brand and stick with them.

You can judge by sales rank and popularity.

Front element size is a good indication of light gathering ability.

Some lenses have better focusing mechanisms, such as SDM.

You can take photos of brick walls and search for distortion.

Many people will buy a lens and use it for a while and see if they like the pictures.

Some people think heavier lenses are better.

Some people judge a lens by its bokeh.

There are too many methods for this thread to be over so quickly.
