I haven't been writing for a while. Been in school in the evening. I finally concluded that it is better to take advantage of the brains out there in improving if I want to be better. Well, I enrolled at Proudphotography.com:  I also upgraded my arsenal. I now have the following lenses along with appropriate filters: http://www.photoafricana.com/product.sc?categoryId=1&productId=11 and http://www.photoafricana.com/product.sc?productId=13. We also have them in stock and for sale at our store - www.photoafricana.com.
