Chris has been pushing Leo to spend a weekend just shooting with the 50mm lens. It's a great lens. Why?
1) It's boring. It's not a special lens, so it forces you to compose better pictures. It's great for remembering the basics.
2) 50mm f1.8 or below gives you more light, and lets you take more natural photos.
3) Better image quality, and bokeh (that out of focus background to make your portraits so good)
4) You can add a few extension tubes and make it into a great macro lens.
Tips - Be deliberate with your photo composition. Don't just take a snapshot. Limit it to what's important to the image. Use manual focus. That forces you to think more about where you're standing, you may have to move forward to get a better, sharper image.
Don't forget our current assignment - "eyes". Take a photo of, about or otherwise concerning the concept of "eyes" and then post it to the Tech Guy Group on Flickr. Make sure to tag it with the word "eyes" as well! And if Chris likes it, it could end up on next month's photo contest review segment!
