not really.. i'm easy both ways, maybe the only small factor is
that i'm used to my nikon (altho a dSLR would be different again)
and i have an sb80... but that can be sold and then top up for a
550!
i've read a few reviews comparing the two cams.. the general
concensus is that canon produces better out of cam pics, but if u
know wat u're doing in ps (or other photo editing software) the
d100 will be more powerful?? man no idea lar.. i'll research more
when the time comes.
oh one up for 10d, it has a better burst/continuous mode. bigger
buffer i think?
