I just recently purchased a Canon Xt, which is my first SLR. First off I am amazed at the difference between a $100-$200 point 'n shoot and a DSLR! I am still learning all of the functions of the camera, and am trying to learn proper ways to compose a picture instead of just taking snapshots of something. I know the affect of polarizers, and am looking at possibly buying one such as a Hoya Pro1 or a B+W multi coated circular polarizer. Is it too early for me to consider adding filters (other than a UV)? Should I just focus on just learning the camera first before getting into filters?
