I just bought a 400D recently
And was wondering what are the filters that are most commonly use and the one that i can try with?
And what are different filters for
Please educate me
You may want to take into account what kind of lens you have for the circular polarizing filter. If the front element of your lens rotates, then the CPL filter 'setting' will get affected.
be sure to get yourself one of better make and quality. there's no point cheapening out on a $40 filter in front of a lens that is way much more expensive. a poor piece of glass in front of a good glass only transmits poorer light to your sensor.
