This has probably been asked before but I really don't understand what products support what features of canon Flashes when browsing BH and Adorama. I want to play with off camera flash but I current only have a 430ex on my 50D. I was going to buy the Canon ST-E2 but I am wary of the range and directivity issues.
So my question is what is generally accepted as an affordable way of, I assume, radio controlling my flash off camera. What features will I be able to use and what limitations do they have. Thanks!
