So late next week im off to New York, Philly and Washington. Im taking my 7D, 10-22 and 70-200 f4 IS, while im there Im picking up a 17-55 IS . Since i had to put a value to all of my camera stuff when i got my travel insurance i can bring either my 50 f1.4 (Canon) or a my 430 EX (and still have it all insured).
Since im picking up my 17-55 while there, i dont really know what the difference in IQ is between them and how the extra light v IS on the prime compares.
So in my position, would you bring the 50 f/1.4 or the 430 EX to supplement my gear?
