Good advice, though I would probably stop far short of the EM in
my selection of my one-and-only Nikon body, and there is a good
selection of new and used mid-priced bodies available (though I
must admit to having a soft spot in my head (;-) for the F3....)
I do like the Sigma 90mm macro, and the Sigma 8mm fisheye, but that
should not be taken as an endorsement of other Sigma lenses.....
Hope This Helps
