I've had my Canon XSi (first DSLR) with 18-55 and 55-250 since Christmas of 08 and I'm loving it! But I am feeling the need for a better flash and a polarizing filter. I'm thinking the 430 EXII is going to be the way to go for me ... The next better canon brand flash is 120 bucks more and I don't think that money would be well spent on my amateur photography right now. . . Something I would really really like would be to use the flash off of the camera ... ie it sitting to the side of a subject and the camera angled from it ... but this doesn't sound possible unless I purchase some additional hardware. Is this correct or am I missing something? Is there a better flash than the 430 EXII or something comprable in the price range I should look at before buying it ? On the polarizing filter ... BHPhotovideo has 2 58mm canon polarizing filters Polarizer Filters | B&H Photo Video There is a 35 dollar price difference and I cannot see anything different about these two filters ... can anyone help me out on this? Thanks for any and all input !
