Ok, i just got a Tamron 75-300 f4-5.6 lens, and now i need a circular polarizer, in 62mm. I know there are a zillion different makes, but i need something inexpensive, but something thats going to work. I already have a tiffen UV filter on it (gotta protect it) I shoot 35mm if that makes a difference? i want to keep price as LOW as possible.. Also: need a good intro to photography book or even a little more advanced book to help me out. i used to see them everywhere, but it seems its all digital now untill digital sensors are same size as a 35mm frame, im not going to bother (shouldnt be too much longer) again, no 50 dollar books here, want to stay 20 or under if possible... I have a canon eos A2 on the way to replace my rebel G, i like some of the features on the A2 much better than my rebel, as well as having a little more camera to hold onto. well thanks everyone for help, Im waiting (patiently...) for spring to REALLY get here so i can go take pictures!!!
