Hi,
I am looking to purchase one of three flashes canon has to offer. I could not find much reviews on them. I am looking at the Speedlite 420EX, 540EX and 550EX.
I only use flash in indoors, sometimes in low illuminated rooms like a dim restaurant for example. Is the 420 good enough or would I need to go to the 540 or 550?
Thanks,
Hugh
