I just found out about this site called lenshero. According to lifehacker it's a great catalog of digital camera lenses so you can easily compare them. That way you can see side-by-side all the information you'd need to make your next purchase...magnification, image stabilization, zoom range, focal length, really everything. If you're into cameras or looking to buy a new lens, it's definitely worth checking out. Plus they have a great contest going right now with really decent chances of winning a lens. I've only looked around a little bit on the site, but so far it looks prety simple too. You put in your price range, what kind of photos you want to shoot, and can select from various types of lenses. You can also filter the results that come up, pretty nice overall. Hope you enjoy!
