I just recently bought a new sony a300 dslr and am now in the market for a few decent filters to add to my bag. I currently have a CP and UV filter and was thinking about buying a ND, diffuser, and maybe a cross star 8 point filter. I am not looking to break the bank with these filters so i am looking for a good trade off of value and quality. I am by no means a professional photographer and really only need these filters to add moderate effect to my pictures. If anyone knows of a good brand or place to get some of these filters cheap please feel free to share some advice . Or if anyone can think of an important filter that i forgot to mention that i might need.Thank!!
